Get events from an event queue

GET https://cs6170-23.zulipchat.com/api/v1/events

This endpoint allows you to receive new events from a registered event queue.

Long-lived clients should use the event_queue_longpoll_timeout_seconds property returned by POST /register as the client-side HTTP request timeout for calls to this endpoint. It is guaranteed to be higher than heartbeat frequency and should be respected by clients to avoid breaking when heartbeat frequency increases.

Usage examples

#!/usr/bin/env python3

import sys
import zulip

# Pass the path to your zuliprc file here.
client = zulip.Client(config_file="~/zuliprc")

# If you already have a queue registered, and thus have a `queue_id`
# on hand, you may use `client.get_events()` and pass in the below
# parameters, like so:
result = client.get_events(queue_id=queue_id, last_event_id=-1)
print(result)

const zulipInit = require("zulip-js");

// Pass the path to your zuliprc file here.
const config = { zuliprc: "zuliprc" };

(async () => {
    const client = await zulipInit(config);

    // Retrieve events from a queue with given "queue_id"
    const eventParams = {
        queue_id,
        last_event_id: -1,
    };

    console.log(await client.events.retrieve(eventParams));
})();

curl -sSX GET -G https://cs6170-23.zulipchat.com/api/v1/events \
    -u BOT_EMAIL_ADDRESS:BOT_API_KEY \
    --data-urlencode queue_id=fb67bf8a-c031-47cc-84cf-ed80accacda8 \

  • When the value of a user's delivery email as visible to you changes, either due to the email address changing or your access to the user's email changing via an update to their email_address_visibility setting.

    Changes: Prior to Zulip 7.0 (feature level 163), this event was sent only to the affected user, and this event would only be triggered by changing the affected user's delivery email.

    • user_id: integer

      The ID of the user affected by this change.

    • delivery_email: string | null

      The new delivery email of the user.

      This value can be null if the affected user changed their email_address_visibility setting such that you cannot access their real email.

  • When a user is deactivated or reactivated. Only users who can access the modified user under the organization's can_access_all_users_group policy will receive this event.

    Clients receiving a deactivation event should remove the user from all user groups in their data structures, because deactivated users cannot be members of groups.

    Changes: Prior to Zulip 10.0 (feature level 303), reactivation events were sent to users who could not access the reactivated user due to a can_access_all_users_group policy. Also, previously, Clients were not required to update group membership records during user deactivation.

    New in Zulip 8.0 (feature level 222). Previously the server sent a realm_user event with op field set to remove when deactivating a user and a realm_user event with op field set to add when reactivating a user.

    • user_id: integer

      The ID of the user affected by this change.

    • is_active: boolean

        "avatar_url": "https://secure.gravatar.com/avatar/6d8cad0fd00256e7b40691d27ddfd466?d=identicon&version=3",
        "avatar_url_medium": "https://secure.gravatar.com/avatar/6d8cad0fd00256e7b40691d27ddfd466?d=identicon&s=500&version=3",
        "avatar_version": 3,
        "user_id": 10

    The description of the channel in text/markdown format, intended to be used to prepopulate UI for editing a channel's description.

    See also rendered_description.

  • rendered_description: string

    The description of the channel rendered as HTML, intended to be used when displaying the channel description in a UI.

    One should use the standard Zulip rendered_markdown CSS when displaying this content so that emoji, LaTeX, and other syntax work correctly. And any client-side security logic for user-generated message content should be applied when displaying this HTML as though it were the body of a Zulip message.

    See also description.

  • date_created: integer

    The UNIX timestamp for when the channel was created, in UTC seconds.

    Changes: New in Zulip 4.0 (feature level 30).

  • creator_id: integer | null

  • invite_only: boolean

    Specifies whether the channel is private or not. Only people who have been invited can access a private channel.

    A null value means the value of this setting should be inherited from the user-level default setting, enable_stream_desktop_notifications, for this channel.

  • email_notifications: boolean | null

    A boolean specifying whether email notifications are enabled for the given channel.

    A null value means the value of this setting should be inherited from the user-level default setting, enable_stream_email_notifications, for this channel.

  • wildcard_mentions_notify: boolean | null

    A boolean specifying whether wildcard mentions trigger notifications as though they were personal mentions in this channel.

    A null value means the value of this setting should be inherited from the user-level default setting, wildcard_mentions_notify, for this channel.

  • push_notifications: boolean | null

    A boolean specifying whether push notifications are enabled for the given channel.

    A null value means the value of this setting should be inherited from the user-level default setting, enable_stream_push_notifications, for this channel.

  • audible_notifications: boolean | null

    A boolean specifying whether audible notifications are enabled for the given channel.

    A null value means the value of this setting should be inherited from the user-level default setting, enable_stream_audible_notifications, for this channel.

  • pin_to_top: boolean

    A boolean specifying whether the given channel has been pinned to the top.

  • is_muted: boolean

    Whether the user has muted the channel. Muted channels do not count towards your total unread count and do not show up in the Combined feed view (previously known as All messages).

    Changes: Prior to Zulip 2.1.0, this feature was represented by the more confusingly named in_home_view (with the opposite value, in_home_view=!is_muted).

  • in_home_view: boolean

    Legacy property for if the given channel is muted, with inverted meaning.

    Changes: Deprecated in Zulip 2.1.0. Clients should use is_muted where available.

  • is_announcement_only: boolean

    Whether only organization administrators can post to the channel.

    Changes: Deprecated in Zulip 3.0 (feature level 1). Clients should use stream_post_policy instead.

  • is_web_public: boolean

    Whether the channel has been configured to allow unauthenticated access to its message history from the web.

  • color: string

    The user's personal color for the channel.

  • stream_post_policy: integer

    Policy for which users can post messages to the channel.

    • 1 = Any user can post.

    • 3 = Only full members can post.
    • 4 = Only moderators can post.

    Changes: New in Zulip 3.0 (feature level 1), replacing the previous is_announcement_only boolean.

  • message_retention_days: integer | null

    Number of days that messages sent to this channel will be stored before being automatically deleted by the message retention policy. There are two special values:

    • null, the default, means the channel will inherit the organization level setting.
    • -1 encodes retaining messages in this channel forever.

    Changes: New in Zulip 3.0 (feature level 17).

  • history_public_to_subscribers: boolean

    Whether the history of the channel is public to its subscribers.

    Currently always true for public channels (i.e. "invite_only": false implies "history_public_to_subscribers": true), but clients should not make that assumption, as we may change that behavior in the future.

  • first_message_id: integer | null

    The ID of the first message in the channel.

    Intended to help clients determine whether they need to display UI like the "show all topics" widget that would suggest the channel has older history that can be accessed.

    Is null for channels with no message history.

  • stream_weekly_traffic: integer | null

    The average number of messages sent to the channel per week, as estimated based on recent weeks, rounded to the nearest integer.

    If null, the channel was recently created and there is insufficient data to estimate the average traffic.

  • can_remove_subscribers_group: integer

    ID of the user group whose members are allowed to unsubscribe others from the channel.

    Changes: Before Zulip 8.0 (feature level 197), the can_remove_subscribers_group setting was named can_remove_subscribers_group_id.

    New in Zulip 6.0 (feature level 142).

Example

{
    "id": 0,
    "op": "add",
    "subscriptions": [
        {
            "audible_notifications": null,
            "can_remove_subscribers_group": 2,
            "color": "#76ce90",
            "creator_id": null,
            "description": "",
            "desktop_notifications": null,
            "email_notifications": null,
            "first_message_id": null,
            "history_public_to_subscribers": true,
            "in_home_view": true,
            "invite_only": false,
            "is_announcement_only": false,
            "is_muted": false,
            "is_web_public": false,
            "message_retention_days": null,
            "name": "test",
            "pin_to_top": false,
            "push_notifications": null,
            "rendered_description": "",
            "stream_id": 9,
            "stream_post_policy": 1,
            "stream_weekly_traffic": null,
            "subscribers": [
                10
            ],
            "wildcard_mentions_notify": null
        }
    ],
    "type": "subscription"
}

Event sent to a user's clients when that user has been unsubscribed from one or more channels.

• id: integer

  The ID of the event. Events appear in increasing order but may not be consecutive.

• type: string

  The event's type, relevant both for client-side dispatch and server-side filtering by event type in POST /register.

• subscriptions: (object)[]

  A list of dictionaries, where each dictionary contains information about one of the newly unsubscribed channels.

  • stream_id: integer

    The ID of the channel.

  • name: string

    The name of the channel.

Example

{
    "id": 0,
    "op": "remove",
    "subscriptions": [
        {
            "name": "test",
            "stream_id": 9
        }
    ],
    "type": "subscription"
}

Event sent to a user's clients when a property of the user's subscription to a channel has been updated. This event is used only for personal properties like is_muted or pin_to_top. See the stream op: update event for updates to global properties of a channel.

• id: integer

  The ID of the event. Events appear in increasing order but may not be consecutive.

• type: string

  The event's type, relevant both for client-side dispatch and server-side filtering by event type in POST /register.

• stream_id: integer

  The ID of the channel whose subscription details have changed.

• property: string

  The property of the subscription which has changed. For details on the various subscription properties that a user can change, see POST /users/me/subscriptions/properties.

  Clients should generally handle an unknown property received here without crashing, since that will naturally happen when connecting to a Zulip server running a new version that adds a new subscription property.

  Changes: As of Zulip 6.0 (feature level 139), updates to the is_muted property or the deprecated in_home_view property will send two subscription update events, one for each property, to support clients fully migrating to use the is_muted property. Prior to this feature level, updates to either property only sent one event with the deprecated in_home_view property.

• value: integer | boolean | string

  The new value of the changed property.

Example

{
    "id": 0,
    "op": "update",
    "property": "pin_to_top",
    "stream_id": 11,
    "type": "subscription",
    "value": true
}

Event sent when another user subscribes to a channel, or their subscription is newly visible to the current user.

When a user subscribes to a channel, the current user will receive this event only if they have permission to see the channel's subscriber list. When the current user gains permission to see a given channel's subscriber list, they will receive this event for the existing subscriptions to the channel.

Changes: Prior to Zulip 8.0 (feature level 220), this event was incorrectly not sent to guest users when subscribers to web-public channels and subscribed public channels changed.

Prior to Zulip 8.0 (feature level 205), this event was not sent when a user gained access to a channel due to their role changing.

Prior to Zulip 6.0 (feature level 134), this event was not sent when a private channel was made public.

In Zulip 4.0 (feature level 35), the singular user_id and stream_id integers included in this event were replaced with plural user_ids and stream_ids integer arrays.

In Zulip 3.0 (feature level 19), the stream_id field was added to identify the channel the user subscribed to, replacing the name field.

• id: integer

  The ID of the event. Events appear in increasing order but may not be consecutive.

• type: string

  The event's type, relevant both for client-side dispatch and server-side filtering by event type in POST /register.

  Changes: New in Zulip 4.0 (feature level 35), replacing the stream_id integer.

• user_ids: (integer)[]

  The IDs of the users who are newly visible as subscribed to the specified channels.

  Changes: New in Zulip 4.0 (feature level 35), replacing the user_id integer.

Example

{
    "id": 0,
    "op": "peer_add",
    "stream_ids": [
        9
    ],
    "type": "subscription",
    "user_ids": [
        12
    ]
}

Event sent to other users when users have been unsubscribed from channels. Sent to all users if the channel is public or to only the existing subscribers if the channel is private.

Changes: Prior to Zulip 8.0 (feature level 220), this event was incorrectly not sent to guest users when subscribers to web-public channels and subscribed public channels changed.

In Zulip 4.0 (feature level 35), the singular user_id and stream_id integers included in this event were replaced with plural user_ids and stream_ids integer arrays.

In Zulip 3.0 (feature level 19), the stream_id field was added to identify the channel the user unsubscribed from, replacing the name field.

• id: integer

  The ID of the event. Events appear in increasing order but may not be consecutive.

• type: string

  The event's type, relevant both for client-side dispatch and server-side filtering by event type in POST /register.

• stream_ids: (integer)[]

  The IDs of the channels from which the users have been unsubscribed from.

  Changes: New in Zulip 4.0 (feature level 35), replacing the stream_id integer.

• user_ids: (integer)[]

    "stream_ids": [
        9
    ],
    "type": "subscription",
    "user_ids": [
        12
    ]
}

Event type for messages.

Changes: In Zulip 3.1 (feature level 26), the sender_short_name field was removed from message objects.

• id: integer

  The ID of the event. Events appear in increasing order but may not be consecutive.

• type: string

  The event's type, relevant both for client-side dispatch and server-side filtering by event type in POST /register.

• message: object

  Object containing details of the message.

  • avatar_url: string | null

    The URL of the message sender's avatar. Can be null only if the current user has access to the sender's real email address and client_gravatar was true.

    If null, then the sender has not uploaded an avatar in Zulip, and the client can compute the gravatar URL by hashing the sender's email address, which corresponds in this case to their real email address.

    Changes: Before Zulip 7.0 (feature level 163), access to a user's real email address was a realm-level setting. As of this feature level, email_address_visibility is a user setting.

  • client: string

    A Zulip "client" string, describing what Zulip client sent the message.

  • content: string

    The content/body of the message.

  • content_type: string

    The HTTP content_type for the message content. This will be text/html or text/x-markdown, depending on whether apply_markdown was set.

  • display_recipient: string | (object)[]

    Data on the recipient of the message; either the name of a channel or a dictionary containing basic data on the users who received the message.

  • edit_history: (object)[]

    An array of objects, with each object documenting the changes in a previous edit made to the message, ordered chronologically from most recent to least recent edit.

    Not present if the message has never been edited or if the realm has disabled viewing of message edit history.

    Every object will contain user_id and timestamp.

    The other fields are optional, and will be present or not depending on whether the channel, topic, and/or message content were modified in the edit event. For example, if only the topic was edited, only prev_topic and topic will be present in addition to user_id and timestamp.

    Changes: In Zulip 10.0 (feature level 284), removed the prev_rendered_content_version field as it is an internal server implementation detail not used by any client.

    • prev_content: string

      Only present if message's content was edited.

      The content of the message immediately prior to this edit event.

      Only present if message's topic was edited.

      The topic of the message immediately prior to this edit event.

      Changes: New in Zulip 5.0 (feature level 118). Previously, this field was called prev_subject; clients are recommended to rename prev_subject to prev_topic if present for compatibility with older Zulip servers.

    • stream: integer

      Only present if message's channel was edited.

      The ID of the channel containing the message immediately after this edit event.

      Changes: New in Zulip 5.0 (feature level 118).

      The UNIX timestamp for the edit.

    • topic: string

      Only present if message's topic was edited.

      The topic of the message immediately after this edit event.

      Changes: New in Zulip 5.0 (feature level 118).

    • user_id: integer | null

      The ID of the user that made the edit.

      Will be null only for edit history events predating March 2017.

      Clients can display edit history events where this is null as modified by either the sender (for content edits) or an unknown user (for topic edits).

  • id: integer

    The unique message ID. Messages should always be displayed sorted by ID.

  • is_me_message: boolean

    Whether the message is a /me status message

  • last_edit_timestamp: integer

    The UNIX timestamp for when the message was last edited, in UTC seconds.

    Not present if the message has never been edited.

      Name of the emoji.

    • emoji_code: string

      A unique identifier, defining the specific emoji codepoint requested, within the namespace of the reaction_type.

    • reaction_type: string

      A string indicating the type of emoji. Each emoji reaction_type has an independent namespace for values of emoji_code.

      Must be one of the following values:

      • unicode_emoji : In this namespace, emoji_code will be a dash-separated hex encoding of the sequence of Unicode codepoints that define this emoji in the Unicode specification.

      • realm_emoji : In this namespace, emoji_code will be the ID of the uploaded custom emoji.

      • zulip_extra_emoji : These are special emoji included with Zulip. In this namespace, emoji_code will be the name of the emoji (e.g. "zulip").

    • user_id: integer

      The ID of the user who added the reaction.

      Changes: New in Zulip 3.0 (feature level 2). The user object is deprecated and will be removed in the future.

    • user: object

      Dictionary with data on the user who added the reaction, including the user ID as the id field. Note that reactions data received from the events API has a slightly different user dictionary format, with the user ID field called user_id instead.

      Changes: Deprecated and to be removed in a future release once core clients have migrated to use the adjacent user_id field, which was introduced in Zulip 3.0 (feature level 2). Clients supporting older Zulip server versions should use the user ID mentioned in the description above as they would the user_id field.

      • id: integer

        ID of the user.

      • email: string

        Zulip API email of the user.

      • full_name: string

        Full name of the user.

      • is_mirror_dummy: boolean

        Whether the user is a mirror dummy.

  • recipient_id: integer

    A unique ID for the set of users receiving the message (either a channel or group of users). Useful primarily for hashing.

  • sender_email: string

    The Zulip API email address of the message's sender.

  • sender_full_name: string

    The full name of the message's sender.

  • sender_id: integer

    The user ID of the message's sender.

  • sender_realm_str: string

    A string identifier for the realm the sender is in. Unique only within the context of a given Zulip server.

    E.g. on example.zulip.com, this will be example.

  • stream_id: integer

    Only present for channel messages; the ID of the channel.

  • subject: string

    The topic of the message. Currently always "" for direct messages, though this could change if Zulip adds support for topics in direct message conversations.

    The field name is a legacy holdover from when topics were called "subjects" and will eventually change.

  • submessages: (object)[]

    Data used for certain experimental Zulip integrations.

    • msg_type: string

      The type of the message.

    • content: string

      The new content of the submessage.

    • message_id: integer

      The ID of the message to which the submessage has been added.

    • sender_id: integer

      The ID of the user who sent the message.

    • id: integer

      The ID of the submessage.

  • timestamp: integer

    The UNIX timestamp for when the message was sent, in UTC seconds.

  • topic_links: (object)[]

    Data on any links to be included in the topic line (these are generated by custom linkification filters that match content in the message's topic.)

    Changes: This field contained a list of urls before Zulip 4.0 (feature level 46).

    New in Zulip 3.0 (feature level 1). Previously, this field was called subject_links; clients are recommended to rename subject_links to topic_links if present for compatibility with older Zulip servers.

    • text: string

      The original link text present in the topic.

    • url: string

      The expanded target url which the link points to.

  • type: string

    The type of the message: "stream" or "private".

• flags: (string)[]

  The user's message flags for the message.

  Clients should inspect the flags field rather than assuming that new messages are unread; muted users, messages sent by the current user, and more subtle scenarios can result in a new message that the server has already marked as read for the user.

  Changes: In Zulip 8.0 (feature level 224), the wildcard_mentioned flag was deprecated in favor of the stream_wildcard_mentioned and topic_wildcard_mentioned flags. The wildcard_mentioned flag exists for backwards compatibility with older clients and equals stream_wildcard_mentioned || topic_wildcard_mentioned. Clients supporting older server versions should treat this field as a previous name for the stream_wildcard_mentioned flag as topic wildcard mentions were not available prior to this feature level.

Example

{
    "flags": [],
    "id": 1,
    "message": {
        "avatar_url": null,
        "client": "test suite",
        "content": "<p>First message ...<a href=\"user_uploads/2/ce/2Xpnnwgh8JWKxBXtTfD6BHKV/zulip.txt\">zulip.txt</a></p>",
        "content_type": "text/html",
        "display_recipient": "Denmark",
        "id": 31,
        "is_me_message": false,
        "reactions": [],
        "recipient_id": 23,
        "sender_email": "user10@zulip.testserver",
        "sender_full_name": "King Hamlet",
        "sender_id": 10,
        "sender_realm_str": "zulip",
        "stream_id": 1,
        "subject": "test",
        "submessages": [],
        "timestamp": 1594825416,
        "topic_links": [],
        "type": "stream"
    },
    "type": "message"
}

Event sent to a user's clients when the user completes the OAuth flow for the Zoom integration. Clients need to know whether initiating Zoom OAuth is required before creating a Zoom call.

• id: integer

  The ID of the event. Events appear in increasing order but may not be consecutive.

• type: string

  The event's type, relevant both for client-side dispatch and server-side filtering by event type in POST /register.

• value: boolean

  A boolean specifying whether the user has zoom token or not.

Example

{
    "id": 0,
    "type": "has_zoom_token",
    "value": true
}

A simple event sent when the set of invitations changes. This event is sent to organization administrators and the creator of the changed invitation; this tells clients they need to refetch data from GET /invites if they are displaying UI containing active invitations.

Changes: Before Zulip 8.0 (feature level 209), this event was only sent to organization administrators.

• id: integer

  The ID of the event. Events appear in increasing order but may not be consecutive.

• type: string

  The event's type, relevant both for client-side dispatch and server-side filtering by event type in POST /register.

Example

{
    "id": 0,
    "type": "invites_changed"
}

Event sent to all users in a Zulip organization when a new user joins or when a guest user gains access to a user. Processing this event is important to being able to display basic details on other users given only their ID.

If the current user is a guest whose access to a newly created user is limited by a can_access_all_users_group policy, and the event queue was registered with the user_list_incomplete client capability, then the event queue will not receive an event for such a new user. If a newly created user is inaccessible to the current user via such a policy, but the client lacks user_list_incomplete client capability, then this event will be delivered to the queue, with an "Unknown user" object with the usual format but placeholder data whose only variable content is the user ID.

Changes: Before Zulip 8.0 (feature level 232), the user_list_incomplete client capability did not exist, and so all clients whose access to a new user was prevented by can_access_all_users_group policy would receive a fake "Unknown user" event for such a user.

Starting with Zulip 8.0 (feature level 228), this event is also sent when a guest user gains access to a user.

• id: integer

  The ID of the event. Events appear in increasing order but may not be consecutive.

• type: string

  The event's type, relevant both for client-side dispatch and server-side filtering by event type in POST /register.

• person: object

  A dictionary containing basic data on a given Zulip user.

  • user_id: integer

    The unique ID of the user.

  • delivery_email: string | null

    The user's real email address. This value will be null if you cannot access user's real email address. For bot users, this field is always set to the real email of the bot, because bot users always have email_address_visibility set to everyone.

    Changes: Prior to Zulip 7.0 (feature level 163), this field was present only when email_address_visibility was restricted and you had access to the user's real email. As of this feature level, this field is always present, including the case when email_address_visibility is set to everyone (and therefore not restricted).

  • email: string

    The Zulip API email address of the user or bot.

    If you do not have permission to view the email address of the target user, this will be a fake email address that is usable for the Zulip API but nothing else.

  • full_name: string

    Full name of the user or bot, used for all display purposes.

  • date_joined: string

    The time the user account was created.

  • is_active: boolean

    A boolean specifying whether the user account has been deactivated.

  • is_owner: boolean

    A boolean specifying whether the user is an organization owner. If true, is_admin will also be true.

    Changes: New in Zulip 3.0 (feature level 8).

  • is_admin: boolean

    A boolean specifying whether the user is an organization administrator.

  • is_guest: boolean

    A boolean specifying whether the user is a guest user.

  • is_billing_admin: boolean

    A boolean specifying whether the user is a billing administrator.

    Changes: New in Zulip 5.0 (feature level 73).

  • is_bot: boolean

    A boolean specifying whether the user is a bot or full account.

  • bot_type: integer | null

    An integer describing the type of bot:

    • null if the user isn't a bot.
    • 1 for a Generic bot.
    • 2 for an Incoming webhook bot.
    • 3 for an Outgoing webhook bot.
    • 4 for an Embedded bot.

  • bot_owner_id: integer | null

    If the user is a bot (i.e. is_bot is true), then bot_owner_id is the user ID of the bot's owner (usually, whoever created the bot).

    Will be null for legacy bots that do not have an owner.

    Changes: New in Zulip 3.0 (feature level 1). In previous versions, there was a bot_owner field containing the email address of the bot's owner.

  • role: integer

    Organization-level role of the user. Possible values are:

    • 100 = Organization owner
    • 200 = Organization administrator
    • 300 = Organization moderator
    • 400 = Member
    • 600 = Guest

    Changes: New in Zulip 4.0 (feature level 59).

  • timezone: string

    The time zone of the user.

  • avatar_url: string | null

    URL for the user's avatar.

    Will be null if the client_gravatar query parameter was set to true, the current user has access to this user's real email address, and this user's avatar is hosted by the Gravatar provider (i.e. this user has never uploaded an avatar).

    Changes: Before Zulip 7.0 (feature level 163), access to a user's real email address was a realm-level setting. As of this feature level, email_address_visibility is a user setting.

    In Zulip 3.0 (feature level 18), if the client has the user_avatar_url_field_optional capability, this will be missing at the server's sole discretion.

  • avatar_version: integer

    Version for the user's avatar. Used for cache-busting requests for the user's avatar. Clients generally shouldn't need to use this; most avatar URLs sent by Zulip will already end with ?v={avatar_version}.

  • profile_data: object

    Only present if is_bot is false; bots can't have custom profile fields.

    A dictionary containing custom profile field data for the user. Each entry maps the integer ID of a custom profile field in the organization to a dictionary containing the user's data for that field. Generally the data includes just a single value key; for those custom profile fields supporting Markdown, a rendered_value key will also be present.

    • {id}: object

      Object with data about what value the user filled in the custom profile field with that ID.

      • value: string

        User's personal value for this custom profile field.

      • rendered_value: string

        The value rendered in HTML. Will only be present for custom profile field types that support Markdown rendering.

        This user-generated HTML content should be rendered using the same CSS and client-side security protections as are used for message content.

Example

{
    "id": 0,
    "op": "add",
    "person": {
        "avatar_url": "https://secure.gravatar.com/avatar/c6b5578d4964bd9c5fae593c6868912a?d=identicon&version=1",
        "avatar_version": 1,
        "date_joined": "2020-07-15T15:04:02.030833+00:00",
        "delivery_email": null,
        "email": "foo@zulip.com",
        "full_name": "full name",
        "is_active": true,
        "is_admin": false,
        "is_billing_admin": false,
        "is_bot": false,
        "is_guest": false,
        "is_owner": false,
        "profile_data": {},
        "role": 400,
        "timezone": "",
        "user_id": 38
    },
    "type": "realm_user"
}

Event sent to guest users when they lose access to a user.

Changes: As of Zulip 8.0 (feature level 228), this event is no longer deprecated.

In Zulip 8.0 (feature level 222), this event was deprecated and no longer sent to clients. Prior to this feature level, it was sent to all users in a Zulip organization when a user was deactivated.

• id: integer

  The ID of the event. Events appear in increasing order but may not be consecutive.

• type: string

  The event's type, relevant both for client-side dispatch and server-side filtering by event type in POST /register.

• person: object

  Object containing details of the deactivated user.

  • user_id: integer

    The ID of the deactivated user.

  • full_name: string

    The full name of the user.

    Deprecated: We expect to remove this field in the future.

Example

{
    "id": 0,
    "op": "remove",
    "person": {
        "full_name": "Foo Bot",
        "user_id": 35
    },
    "type": "realm_user"
}

Event sent to all users in an organization when a user comes back online after being offline for a while. While most presence updates are done via polling the main presence endpoint, this event is important to avoid confusing users when someone comes online and immediately sends a message (one wouldn't want them to still appear offline at that point!).

If the CAN_ACCESS_ALL_USERS_GROUP_LIMITS_PRESENCE server-level setting is set to true, then the event is only sent to users who can access the user who came back online.

Changes: Prior to Zulip 8.0 (feature level 228), this event was sent to all users in the organization.

• id: integer

  The ID of the event. Events appear in increasing order but may not be consecutive.

• type: string

  The event's type, relevant both for client-side dispatch and server-side filtering by event type in POST /register.

• user_id: integer

  The ID of the modified user.

• email: string

  The Zulip API email of the user.

  Deprecated: This field will be removed in a future release as it is redundant with the user_id.

• server_timestamp: number

• presence: object

  Object containing the details of the user's most recent presence.

  • {client_name}: object

    Object containing the details of the user's presence.

    Changes: Starting with Zulip 7.0 (feature level 178), this will always be "website" as the server no longer stores which client submitted presence updates.

    Previously, the object key was the client's platform name, for example website or ZulipDesktop.

    • client: string

      The client's platform name.

      Changes: Starting with Zulip 7.0 (feature level 178), this will always be "website" as the server no longer stores which client submitted presence updates.

    • status: string

      The status of the user on this client. Will be either idle or active.

    • timestamp: integer

      The UNIX timestamp of when this client sent the user's presence to the server with the precision of a second.

    • pushable: boolean

      Whether the client is capable of showing mobile/push notifications to the user.

      Changes: Starting with Zulip 7.0 (feature level 178), this will always be false as the server no longer stores which client submitted presence updates.

Example

{
    "email": "user10@zulip.testserver",
    "id": 0,
    "presence": {
        "website": {
            "client": "website",
            "pushable": false,
            "status": "idle",
            "timestamp": 1594825445
        }
    },
    "server_timestamp": 1594825445.3200784,
    "type": "presence",
    "user_id": 10
}

Event sent when a new channel is created to users who can see the new channel exists (for private channels, only subscribers and organization administrators will receive this event).

This event is also sent when a user gains access to a channel they previously could not access, such as when their role changes, a private channel is made public, or a guest user is subscribed to a public (or private) channel.

Note that organization administrators who are not subscribed will not be able to see content on the channel; just that it exists.

Changes: Prior to Zulip 8.0 (feature level 220), this event was incorrectly not sent to guest users a web-public channel was created.

Prior to Zulip 8.0 (feature level 205), this event was not sent when a user gained access to a channel due to their role changing.

Prior to Zulip 8.0 (feature level 192), this event was not sent when guest users gained access to a public channel by being subscribed.

Prior to Zulip 6.0 (feature level 134), this event was not sent when a private channel was made public.

• id: integer

  The ID of the event. Events appear in increasing order but may not be consecutive.

• type: string

  The event's type, relevant both for client-side dispatch and server-side filtering by event type in POST /register.

• streams: (object)[]

  • stream_id: integer

    The unique ID of the channel.

  • name: string

  • description: string

    The short description of the channel in text/markdown format, intended to be used to prepopulate UI for editing a channel's description.

  • date_created: integer

    The UNIX timestamp for when the channel was created, in UTC seconds.

    Changes: New in Zulip 4.0 (feature level 30).

  • creator_id: integer | null

    The ID of the user who created this channel.

    A null value means the channel has no recorded creator, which is often because the channel is very old, or because it was created via a data import tool or management command.

    Changes: New in Zulip 9.0 (feature level 254).

  • invite_only: boolean

    Specifies whether the channel is private or not. Only people who have been invited can access a private channel.

  • rendered_description: string

    The short description of the channel rendered as HTML, intended to be used when displaying the channel description in a UI.

    One should use the standard Zulip rendered_markdown CSS when displaying this content so that emoji, LaTeX, and other syntax work correctly. And any client-side security logic for user-generated message content should be applied when displaying this HTML as though it were the body of a Zulip message.

  • is_web_public: boolean

    Whether the channel has been configured to allow unauthenticated access to its message history from the web.

    Changes: New in Zulip 2.1.0.

  • stream_post_policy: integer

    Policy for which users can post messages to the channel.

    • 1 = Any user can post.
    • 2 = Only administrators can post.
    • 3 = Only full members can post.
    • 4 = Only moderators can post.

    Changes: New in Zulip 3.0 (feature level 1), replacing the previous is_announcement_only boolean.

  • message_retention_days: integer | null

    Number of days that messages sent to this channel will be stored before being automatically deleted by the message retention policy. There are two special values:

    • null, the default, means the channel will inherit the organization level setting.
    • -1 encodes retaining messages in this channel forever.

    Changes: New in Zulip 3.0 (feature level 17).

  • history_public_to_subscribers: boolean

    Whether the history of the channel is public to its subscribers.

    Currently always true for public channels (i.e. "invite_only": false implies "history_public_to_subscribers": true), but clients should not make that assumption, as we may change that behavior in the future.

  • first_message_id: integer | null

    The ID of the first message in the channel.

    Intended to help clients determine whether they need to display UI like the "show all topics" widget that would suggest the channel has older history that can be accessed.

    Is null for channels with no message history.

    Changes: New in Zulip 2.1.0.

  • is_announcement_only: boolean

    Whether the given channel is announcement only or not.

    Changes: Deprecated in Zulip 3.0 (feature level 1). Clients should use stream_post_policy instead.

  • can_remove_subscribers_group: integer

    ID of the user group whose members are allowed to unsubscribe others from the channel.

    Changes: Before Zulip 8.0 (feature level 197), the can_remove_subscribers_group setting was named can_remove_subscribers_group_id.

    New in Zulip 6.0 (feature level 142).

  • stream_weekly_traffic: integer | null

    The average number of messages sent to the channel per week, as estimated based on recent weeks, rounded to the nearest integer.

    If null, no information is provided on the average traffic. This can be because the channel was recently created and there is insufficient data to make an estimate, or because the server wishes to omit this information for this client, this realm, or this endpoint or type of event.

    Changes: New in Zulip 8.0 (feature level 199). Previously, this statistic was available only in subscription objects.

Example

{
    "id": 0,
    "op": "create",
    "streams": [
        {
            "can_remove_subscribers_group": 2,

        }
    ],
    "type": "stream"
}

Event sent to all users who can see a channel when it is deactivated.

This event is also sent when a user loses access to a channel they previously could access because they are unsubscribed from a private channel or their role has changed.

Changes: Prior to Zulip 8.0 (feature level 205), this event was not sent when a user lost access to a channel due to their role changing.

• id: integer

  The ID of the event. Events appear in increasing order but may not be consecutive.

• type: string

  The event's type, relevant both for client-side dispatch and server-side filtering by event type in POST /register.

  Array of objects, each containing details about a channel that was deleted.

  • stream_id: integer

    The unique ID of the channel.

  • name: string

    The name of the channel.

    Changes: New in Zulip 4.0 (feature level 30).

  • creator_id: integer | null

    The ID of the user who created this channel.

    A null value means the channel has no recorded creator, which is often because the channel is very old, or because it was created via a data import tool or management command.

    Changes: New in Zulip 9.0 (feature level 254).

  • invite_only: boolean

    Specifies whether the channel is private or not. Only people who have been invited can access a private channel.

  • rendered_description: string

    The short description of the channel rendered as HTML, intended to be used when displaying the channel description in a UI.

    One should use the standard Zulip rendered_markdown CSS when displaying this content so that emoji, LaTeX, and other syntax work correctly. And any client-side security logic for user-generated message content should be applied when displaying this HTML as though it were the body of a Zulip message.

  • is_web_public: boolean

    Whether the channel has been configured to allow unauthenticated access to its message history from the web.

    Changes: New in Zulip 2.1.0.

  • stream_post_policy: integer

    Policy for which users can post messages to the channel.

    • 1 = Any user can post.
    • 2 = Only administrators can post.
    • 3 = Only full members can post.
    • 4 = Only moderators can post.

    Changes: New in Zulip 3.0 (feature level 1), replacing the previous is_announcement_only boolean.

  • message_retention_days: integer | null

    Number of days that messages sent to this channel will be stored before being automatically deleted by the message retention policy. There are two special values:

    • null, the default, means the channel will inherit the organization level setting.
    • -1 encodes retaining messages in this channel forever.

    Changes: New in Zulip 3.0 (feature level 17).

  • history_public_to_subscribers: boolean

    Whether the history of the channel is public to its subscribers.

    Currently always true for public channels (i.e. "invite_only": false implies "history_public_to_subscribers": true), but clients should not make that assumption, as we may change that behavior in the future.

  • first_message_id: integer | null

    The ID of the first message in the channel.

    Intended to help clients determine whether they need to display UI like the "show all topics" widget that would suggest the channel has older history that can be accessed.

    Is null for channels with no message history.

    Changes: New in Zulip 2.1.0.

  • is_announcement_only: boolean

    Whether the given channel is announcement only or not.

    Changes: Deprecated in Zulip 3.0 (feature level 1). Clients should use stream_post_policy instead.

  • can_remove_subscribers_group: integer

    ID of the user group whose members are allowed to unsubscribe others from the channel.

    Changes: Before Zulip 8.0 (feature level 197), the can_remove_subscribers_group setting was named can_remove_subscribers_group_id.

    New in Zulip 6.0 (feature level 142).

  • stream_weekly_traffic: integer | null

    The average number of messages sent to the channel per week, as estimated based on recent weeks, rounded to the nearest integer.

    If null, no information is provided on the average traffic. This can be because the channel was recently created and there is insufficient data to make an estimate, or because the server wishes to omit this information for this client, this realm, or this endpoint or type of event.

    Changes: New in Zulip 8.0 (feature level 199). Previously, this statistic was available only in subscription objects.

Example

{
    "id": 0,
    "op": "delete",

        {
            "can_remove_subscribers_group": 2,

  The new value of the changed property.

• rendered_description: string

  Note: Only present if the changed property was description.

  The short description of the channel rendered as HTML, intended to be used when displaying the channel description in a UI.

  Note: Only present if the changed property was invite_only.

  Whether the history of the channel is public to its subscribers.

Event sent to all users in a Zulip organization when an organization administrator changes the organization's configured default channel groups.

Default channel groups are an experimental feature that is not yet stabilized.

• id: integer

  The ID of the event. Events appear in increasing order but may not be consecutive.

• type: string

  The event's type, relevant both for client-side dispatch and server-side filtering by event type in POST /register.

• default_stream_groups: (object)[]

  An array of dictionaries where each dictionary contains details about a single default channel group.

  • name: string

    Name of the default channel group.

  • description: string

    Description of the default channel group.

  • id: integer

    The ID of the default channel group.

  • streams: (object)[]

    Array containing details about the channels in the default channel group.

    • stream_id: integer

      The unique ID of the channel.

    • name: string

      The name of the channel.

    • description: string

      The short description of the channel in text/markdown format, intended to be used to prepopulate UI for editing a channel's description.

    • date_created: integer

      The UNIX timestamp for when the channel was created, in UTC seconds.

      Changes: New in Zulip 4.0 (feature level 30).

    • creator_id: integer | null

      The ID of the user who created this channel.

      A null value means the channel has no recorded creator, which is often because the channel is very old, or because it was created via a data import tool or management command.

      Changes: New in Zulip 9.0 (feature level 254).

    • invite_only: boolean

      Specifies whether the channel is private or not. Only people who have been invited can access a private channel.

    • rendered_description: string

      The short description of the channel rendered as HTML, intended to be used when displaying the channel description in a UI.

      One should use the standard Zulip rendered_markdown CSS when displaying this content so that emoji, LaTeX, and other syntax work correctly. And any client-side security logic for user-generated message content should be applied when displaying this HTML as though it were the body of a Zulip message.

    • is_web_public: boolean

      Whether the channel has been configured to allow unauthenticated access to its message history from the web.

      Changes: New in Zulip 2.1.0.

    • stream_post_policy: integer

      Policy for which users can post messages to the channel.

      • 1 = Any user can post.
      • 2 = Only administrators can post.
      • 3 = Only full members can post.
      • 4 = Only moderators can post.

      Changes: New in Zulip 3.0 (feature level 1), replacing the previous is_announcement_only boolean.

    • message_retention_days: integer | null

      Number of days that messages sent to this channel will be stored before being automatically deleted by the message retention policy. There are two special values:

      • null, the default, means the channel will inherit the organization level setting.
      • -1 encodes retaining messages in this channel forever.

      Changes: New in Zulip 3.0 (feature level 17).

    • history_public_to_subscribers: boolean

      Whether the history of the channel is public to its subscribers.

      Currently always true for public channels (i.e. "invite_only": false implies "history_public_to_subscribers": true), but clients should not make that assumption, as we may change that behavior in the future.

    • first_message_id: integer | null

      The ID of the first message in the channel.

      Intended to help clients determine whether they need to display UI like the "show all topics" widget that would suggest the channel has older history that can be accessed.

      Is null for channels with no message history.

      Changes: New in Zulip 2.1.0.

    • is_announcement_only: boolean

      Whether the given channel is announcement only or not.

      Changes: Deprecated in Zulip 3.0 (feature level 1). Clients should use stream_post_policy instead.

    • can_remove_subscribers_group: integer

      ID of the user group whose members are allowed to unsubscribe others from the channel.

      Changes: Before Zulip 8.0 (feature level 197), the can_remove_subscribers_group setting was named can_remove_subscribers_group_id.

      New in Zulip 6.0 (feature level 142).

Event sent when a message has been deleted.

Sent to all users who currently are subscribed to the messages' recipient. May also be sent to additional users who had access to it, including, in particular, an administrator user deleting messages in a stream that they are not subscribed to.

This means that clients can assume that they will always receive an event of this type for deletions that the client itself initiated.

This event is also sent when the user loses access to a message, such as when it is moved to a channel that the user does not have permission to access.

Changes: Before Zulip 9.0 (feature level 274), this event was only sent to subscribers of the message's recipient.

Before Zulip 5.0 (feature level 77), events for direct messages contained additional sender_id and recipient_id fields.

• id: integer

  The ID of the event. Events appear in increasing order but may not be consecutive.

• type: string

  The event's type, relevant both for client-side dispatch and server-side filtering by event type in POST /register.

• message_ids: (integer)[]

  Only present for clients that support the bulk_message_deletion client capability.

  A list containing the IDs of the newly deleted messages.

• message_id: integer

  Only present for clients that do not support the bulk_message_deletion client capability.

  The ID of the newly deleted message.

• message_type: string

  The type of message. Either "stream" or "private".

• stream_id: integer

  Only present if message_type is "stream".

  The ID of the channel to which the message was sent.

• topic: string

  Only present if message_type is "stream".

  The topic to which the message was sent.

Example

{
    "id": 0,
    "message_id": 37,
    "message_type": "private",
    "type": "delete_message"
}

Event sent to a user's clients when that user's set of configured muted topics have changed.

• id: integer

  The ID of the event. Events appear in increasing order but may not be consecutive.

• type: string

  The event's type, relevant both for client-side dispatch and server-side filtering by event type in POST /register.

• muted_topics: ((string | integer)[])[]

  Array of tuples, where each tuple describes a muted topic. The first element of the tuple is the channel name in which the topic has to be muted, the second element is the topic name to be muted and the third element is an integer UNIX timestamp representing when the topic was muted.

  Changes: Deprecated in Zulip 6.0 (feature level 134). Starting with this version, clients that explicitly requested the replacement user_topic event type when registering their event queue will not receive this legacy event type.

  Before Zulip 3.0 (feature level 1), the muted_topics array objects were 2-item tuples and did not include the timestamp information for when the topic was muted.

Example

{
    "id": 0,
    "muted_topics": [
        [
            "Denmark",
            "topic",
            1594825442
        ]
    ],
    "type": "muted_topics"
}

Event sent to a user's clients when the user mutes/unmutes a topic, or otherwise modifies their personal per-topic configuration.

Changes: New in Zulip 6.0 (feature level 134). Previously, clients were notified about changes in muted topic configuration via the muted_topics event type.

• id: integer

  The ID of the event. Events appear in increasing order but may not be consecutive.

• type: string

  The event's type, relevant both for client-side dispatch and server-side filtering by event type in POST /register.

• stream_id: integer

  The ID of the channel to which the topic belongs.

• topic_name: string

  The name of the topic.

• last_updated: integer

  An integer UNIX timestamp representing when the user-topic relationship was last changed.

• visibility_policy: integer

  An integer indicating the user's visibility preferences for the topic, such as whether the topic is muted.

  • 0 = None. Used to indicate that the user no longer has a special visibility policy for this topic.
  • 1 = Muted. Used to record muted topics.
  • 2 = Unmuted. Used to record unmuted topics.
  • 3 = Followed. Used to record followed topics.

  Changes: In Zulip 7.0 (feature level 219), added followed as a visibility policy option.

  In Zulip 7.0 (feature level 170), added unmuted as a visibility policy option.

Example

{
    "id": 1,
    "last_updated": 1594825442,
    "stream_id": 1,
    "topic_name": "topic",
    "type": "user_topic",
    "visibility_policy": 1
}

Event sent to a user's clients when that user's set of configured muted users have changed.

Changes: New in Zulip 4.0 (feature level 48).

• id: integer

  The ID of the event. Events appear in increasing order but may not be consecutive.

• type: string

  The event's type, relevant both for client-side dispatch and server-side filtering by event type in POST /register.

• muted_users: (object)[]

  A list of dictionaries where each dictionary describes a muted user.

  • id: integer

    The ID of the muted user.

  • timestamp: integer

    An integer UNIX timestamp representing when the user was muted.

Example

{
    "id": 0,
    "muted_users": [
        {
            "id": 1,
            "timestamp": 1594825442
        },
        {
            "id": 22,
            "timestamp": 1654865392
        }
    ],
    "type": "muted_users"
}

Heartbeat events are sent by the server to avoid longpolling connections being affected by networks that kill idle HTTP connections.

Clients do not need to do anything to process these events, beyond the common last_event_id accounting.

• id: integer

  The ID of the event. Events appear in increasing order but may not be consecutive.

• type: string

  The event's type, relevant both for client-side dispatch and server-side filtering by event type in POST /register.

Example

{
    "id": 0,
    "type": "heartbeat"
}

Event sent when the set of onboarding steps to show for the current user has changed (e.g. because the user dismissed one).

Clients that feature a similar tutorial experience to the Zulip web app may want to handle these events.

Changes: Before Zulip 8.0 (feature level 233), this event was named hotspots. Prior to this feature level, one-time notice onboarding steps were not supported.

• id: integer

  The ID of the event. Events appear in increasing order but may not be consecutive.

• type: string

  The event's type, relevant both for client-side dispatch and server-side filtering by event type in POST /register.

• onboarding_steps: (object)[]

  An array of dictionaries where each dictionary contains details about a single onboarding step.

  Changes: Before Zulip 8.0 (feature level 233), this array was named hotspots. Prior to this feature level, one-time notice onboarding steps were not supported, and the type field in these objects did not exist as all onboarding steps were implicitly hotspots.

  • type: string

    The type of the onboarding step. Valid value is "one_time_notice".

    Changes: Removed type "hotspot" in Zulip 9.0 (feature level 259).

    New in Zulip 8.0 (feature level 233).

  • name: string

    The name of the onboarding step.

Example

{
    "id": 0,
    "onboarding_steps": [
        {
            "name": "visibility_policy_banner",
            "type": "one_time_notice"
        }
    ],
    "type": "onboarding_steps"
}

Event sent when a message's content, topic and/or channel has been edited or when a message's content has a rendering update, such as for an inline URL preview. Sent to all users who had received the original message.

Changes: In Zulip 10.0 (feature level 284), removed the prev_rendered_content_version field as it is an internal server implementation detail not used by any client.

• id: integer

  The ID of the event. Events appear in increasing order but may not be consecutive.

• type: string

  The event's type, relevant both for client-side dispatch and server-side filtering by event type in POST /register.

• user_id: integer | null

  The ID of the user who sent the message.

  Is null when event is for a rendering update of the original message, such as for an inline URL preview.

  Changes: As of Zulip 5.0 (feature level 114), this field is present for all update_message events. Previously, this field was omitted for inline URL preview updates.

• rendering_only: boolean

  Whether the event only updates the rendered content of the message.

  This field should be used by clients to determine if the event only provides a rendering update to the message content, such as for an inline URL preview. When true, the event does not reflect a user-generated edit and does not modify the message history.

  Changes: New in Zulip 5.0 (feature level 114). Clients can correctly identify these rendering update event with earlier Zulip versions by checking whether the user_id field was omitted.

• message_id: integer

  The ID of the message which was edited or updated.

  This field should be used to apply content edits to the client's cached message history, or to apply rendered content updates.

  If the channel or topic was changed, the set of moved messages is encoded in the separate message_ids field, which is guaranteed to include message_id.

• message_ids: (integer)[]

  The list of IDs of messages to which any channel or topic changes encoded in this event should be applied.

  This list always includes message_id, even when there are no channel or topic changes to apply.

  These messages are guaranteed to have all been previously sent to channel stream_id with topic orig_subject, and have been moved to new_stream_id with topic subject (if those fields are present in the event).

  Clients processing these events should update all cached message history associated with the moved messages (including adjusting unread_msgs data structures, where the client may not have the message itself in its history) to reflect the new channel and topic.

  Content changes should be applied only to the single message indicated by message_id.

• flags: (string)[]

  The user's personal message flags for the message with ID message_id following the edit.

  A client application should compare these to the original flags to identify cases where a mention or alert word was added by the edit.

  Changes: In Zulip 8.0 (feature level 224), the wildcard_mentioned flag was deprecated in favor of the stream_wildcard_mentioned and topic_wildcard_mentioned flags. The wildcard_mentioned flag exists for backwards compatibility with older clients and equals stream_wildcard_mentioned || topic_wildcard_mentioned. Clients supporting older server versions should treat this field as a previous name for the stream_wildcard_mentioned flag as topic wildcard mentions were not available prior to this feature level.

• edit_timestamp: integer

  The time when this message edit operation was processed by the server.

  Changes: As of Zulip 5.0 (feature level 114), this field is present for all update_message events. Previously, this field was omitted for inline URL preview updates.

• stream_name: string

  Only present if the message was edited and originally sent to a channel.

  The name of the channel that the message was sent to. Clients are recommended to use the stream_id field instead.

• stream_id: integer

  Only present if the message was edited and originally sent to a channel.

  The pre-edit channel for all of the messages with IDs in message_ids.

  Changes: As of Zulip 5.0 (feature level 112), this field is present for all edits to a channel message. Previously, it was not present when only the content of the channel message was edited.

• new_stream_id: integer

  Only present if message(s) were moved to a different channel.

  The post-edit channel for all of the messages with IDs in message_ids.

• propagate_mode: string

  Only present if this event moved messages to a different topic and/or channel.

  The choice the editing user made about which messages should be affected by a channel/topic edit:

  • "change_one": Just change the one indicated in message_id.
  • "change_later": Change messages in the same topic that had been sent after this one.
  • "change_all": Change all messages in that topic.

  This parameter should be used to decide whether to change navigation and compose box state in response to the edit. For example, if the user was previously in topic narrow, and the topic was edited with "change_later" or "change_all", the Zulip web app will automatically navigate to the new topic narrow. Similarly, a message being composed to the old topic should have its recipient changed to the new topic.

Event sent to a user when message flags are added to messages.

This can reflect a direct user action, or can be the indirect consequence of another action. Whatever the cause, if there's a change in the set of message flags that the user has for a message, then an update_message_flags event will be sent with the change. Note that this applies when the user already had access to the message, and continues to have access to it. When a message newly appears or disappears, a message or delete_message event is sent instead.

Some examples of actions that trigger an update_message_flags event:

• The "starred" flag is added when the user chooses to star a message.
• The "read" flag is added when the user marks messages as read by scrolling through them, or uses Mark all messages as read on a conversation.
• The "read" flag is added when the user mutes a message's sender.
• The "read" flag is added after the user unsubscribes from a channel, or messages are moved to a not-subscribed channel, provided the user can still access the messages at all. Note a delete_message event is sent in the case where the user can no longer access the messages.

In some cases, a change in message flags that's caused by another change may happen a short while after the original change, rather than simultaneously. For example, when messages that were unread are moved to a channel where the user is not subscribed, the resulting change in message flags (and the corresponding update_message_flags event with flag "read") may happen later than the message move itself. The delay in that example is typically at most a few hundred milliseconds and can in rare cases be minutes or longer.

• id: integer

  The ID of the event. Events appear in increasing order but may not be consecutive.

• type: string

  The event's type, relevant both for client-side dispatch and server-side filtering by event type in POST /register.

  Old name for the op field in this event type.

  Deprecated in Zulip 4.0 (feature level 32), and replaced by the op field.

• flag: string

  The flag that was added.

• messages: (integer)[]

  Array containing the IDs of all messages to which the flag was added.

• all: boolean

  Whether the specified flag was added to all messages. This field is only relevant for the "read" flag, and will be false for all other flags.

  When true for the "read" flag, then the messages array will be empty.

    "all": false,
    "flag": "starred",
    "id": 0,
    "messages": [
