Get events from an event queue

GET https://chat.onecount.net/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 above
# parameters, like so:
result = client.get_events(queue_id=queue_id, last_event_id=-1)
print(result)

More examples and documentation can be found here.

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://chat.onecount.net/api/v1/events \
    -u BOT_EMAIL_ADDRESS:BOT_API_KEY \
    --data-urlencode queue_id=fb67bf8a-c031-47cc-84cf-ed80accacda8 \
    --data-urlencode last_event_id=-1

Parameters

queue_id string required

Example: "fb67bf8a-c031-47cc-84cf-ed80accacda8"

The ID of an event queue that was previously registered via POST /api/v1/register (see Register a queue).


last_event_id integer optional

Example: -1

The highest event ID in this queue that you've received and wish to acknowledge. See the code for call_on_each_event in the zulip Python module for an example implementation of correctly processing each event exactly once.


dont_block boolean optional

Example: true

Set to true if the client is requesting a nonblocking reply. If not specified, the request will block until either a new event is available or a few minutes have passed, in which case the server will send the client a heartbeat event.

Defaults to false.


Note: The parameters documented above are optional in the sense that even if you haven't registered a queue by explicitly requesting the POST /register endpoint, you could pass the parameters for the POST /register endpoint to this endpoint and a queue would be registered in the absence of a queue_id.

Response

Return values

  • events: array

    An array of event objects (possibly zero-length if dont_block is set) with IDs newer than last_event_id. Event IDs are guaranteed to be increasing, but they are not guaranteed to be consecutive.

    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 subscribed streams.

    • name: string

      The name of a stream.

    • description: string

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

      See also rendered_description.

    • rendered_description: string

      The description of the stream rendered as HTML, intended to be used when displaying the stream 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 stream was created, in UTC seconds.

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

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

    • email_notifications: boolean | null

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

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

    • wildcard_mentions_notify: boolean | null

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

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

    • push_notifications: boolean | null

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

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

    • audible_notifications: boolean | null

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

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

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

    • email_address: string

      Email address of the given stream, used for sending emails to the stream.

    • is_muted: boolean

      Whether the user has muted the stream. Muted streams do not count towards your total unread count and do not show up in All messages view (previously known as Home view).

      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 stream 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 stream.

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

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

    • color: string

      The user's personal color for the stream.

      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 stream will be stored before being automatically deleted by the message retention policy. There are two special values:

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

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

    • history_public_to_subscribers: boolean

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

      Currently always true for public streams (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 stream.

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

      Null is used for streams with no message history.

    • stream_weekly_traffic: integer | null

      The average number of messages sent to the stream in recent weeks, rounded to the nearest integer.

      Null means the stream was recently created and there is insufficient data to estimate the average traffic.

    • can_remove_subscribers_group_id: integer

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

      Changes: New in Zulip 6.0 (feature level 142).

                10
            ],
            "wildcard_mentions_notify": null
        }
    ],
    "type": "subscription"
}

subscription op: remove

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

  • id: integer

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

    • stream_id: integer

      The ID of the stream.

      The name of the stream.

Example

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

subscription op: update

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

    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.

    The ID of the stream 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",

    • content: string

      The content/body of the message.

        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.

    • reactions: (object)[]

      Data on any reactions to the message.

      • emoji_name: string

        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

          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 stream or group of users). Useful primarily for hashing.

    • sender_email: string

      The Zulip display 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 stream messages; the ID of the stream.

    • subject: string

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

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

    • submessages: (string)[]

      Data used for certain experimental Zulip integrations.

    • 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.

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>",

        "type": "stream"
    },
    "type": "message"
}

  • type: string

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

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

Example

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

  • type: string

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

}

realm_user op: add

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

  • 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 unique ID of the user.

    • 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.

    • 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.

    • 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:

      • Organization owner => 100
      • Organization administrator => 200
      • Organization moderator => 300

    • 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 user filled in the custom profile field with id 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.

        "user_id": 35
    },
    "type": "realm_user"
}

presence

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!).

  • 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.

    "presence": {
        "ZulipAndroid/1.0": {
            "client": "ZulipAndroid/1.0",

}

stream op: create

  • 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.

    • rendered_description: string

      The short description of the stream rendered as HTML, intended to be used when displaying the stream 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 stream has been configured to allow unauthenticated access to its message history from the web.

    • stream_post_policy: integer

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

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

    • history_public_to_subscribers: boolean

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

      Currently always true for public streams (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 stream.

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

      Null is used for streams with no message history.

    • is_announcement_only: boolean

      Whether the given stream is announcement only or not.

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

  • name: string

    The name of the stream whose details have changed.

  • property: string

    The property of the stream which has changed. See /stream GET for details on the various properties of a stream.

      • first_message_id: integer | null

        The id of the first message in the stream.

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

default_streams

Event sent to all users in a Zulip organization when the default streams in the organization are changed by an organization administrator.

  • 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_streams: (object)[]

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

    • stream_id: integer

      The unique ID of the stream.

    • name: string

      The name of the stream.

    • description: string

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

    • date_created: integer

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

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

    • invite_only: boolean

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

    • rendered_description: string

      The short description of the stream rendered as HTML, intended to be used when displaying the stream 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 stream has been configured to allow unauthenticated access to its message history from the web.

    • stream_post_policy: integer

      Policy for which users can post messages to the stream.

      • 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 stream will be stored before being automatically deleted by the message retention policy. There are two special values:

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

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

    • history_public_to_subscribers: boolean

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

      Currently always true for public streams (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 stream.

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

      Null is used for streams with no message history.

    • is_announcement_only: boolean

      Whether the given stream 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_id: integer

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

      Changes: New in Zulip 6.0 (feature level 142).

        {
            "can_remove_subscribers_group_id": 2,
            "description": "Located in the United Kingdom",
            "first_message_id": 1,

            "rendered_description": "<p>Located in the United Kingdom</p>",
            "stream_id": 3,
            "stream_post_policy": 1
        }
    ],
    "id": 0,
    "type": "default_streams"
}

    The message_ids property will be present for clients that support the bulk_message_deletion client capability.

    An containing the IDs of the newly deleted messages.

  • message_id: integer

    The message_id property will be 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'. The other keys present in the event, necessary to update various frontend data structures that might be tracking the message, depend on the message type.

  • stream_id: integer

    Only present for stream messages.

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

  • topic: string

    Only present for stream messages.

    The topic to which the message was sent.

    "message_type": "private",
    "type": "delete_message"
}

muted_topics

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 stream 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.

    Changes: 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"
}

user_topic

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

    • 1 = Muted. Used to record muted topics.

Example

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

muted_users

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.

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

heartbeat

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.

{
    "hotspots": [
        {
            "delay": 0.5,
            "description": "Messages sent to a stream are seen by everyone subscribed to that stream. Try clicking on one of the stream links below.",
            "name": "intro_streams",
            "title": "Catch up on a stream"
        }
    ],
    "id": 0,
    "type": "hotspots"
}

update_message

Event sent when a message's content, topic and/or stream 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.

  • 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.

    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 stream 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 stream or topic changes encoded in this event should be applied.

    These messages are guaranteed to have all been previously sent to stream 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 stream 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.

  • 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 stream.

    The name of the stream 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 stream.

    The pre-edit stream 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 stream message. Previously, it was not present when only the content of the stream message was edited.

  • new_stream_id: integer

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

    The post-edit stream 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 stream.

    The choice the editing user made about which messages should be affected by a stream/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.

    This navigation makes it much more convenient to move content between topics without disruption or messages continuing to be sent to the pre-edit topic by accident.

  • orig_subject: string

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

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

  • subject: string

    Only present if this event moved messages to a different topic.

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

  • topic_links: (object)[]

    Only present if this event moved messages to a different topic.

    Data on any links to be included in the topic line (these are generated by custom linkification filter that match content in the message's topic.), corresponding to the post-edit 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.

  • orig_content: string

    Only present if this event changed the message content.

    The original content of the message with ID message_id immediately prior to this edit, in the original markdown.

  • orig_rendered_content: string

    Only present if this event changed the message content.

    The original content of the message with ID message_id immediately prior to this edit, rendered as HTML.

  • prev_rendered_content_version: integer

    Only present if this event changed the message content.

    The Markdown processor version number for the pre-edit message.

    Clients should ignore this field.

  • content: string

    Only present if this event changed the message content or updated the message content for an inline URL preview.

    The new content of the message with ID message_id, in the original Markdown.

  • rendered_content: string

    Only present if this event changed the message content or updated the message content for an inline URL preview.

    The new content of the message with ID message_id, rendered in HTML.

  • is_me_message: boolean

    Only present if this event changed the message content.

    Whether the message with ID message_id is now a /me status message.

Example

{
    "content": "new content",
    "edit_timestamp": 1594825451,

    • full_name: string

      The full name of the bot.

    • api_key: string

      The API key of the bot which it uses to make API requests.

      The "Services" array contains extra configuration fields only relevant for Outgoing webhook bots and Embedded bots. It is always a single-element array.

      We consider this part of the Zulip API to be unstable; it is used only for UI elements for administering bots and is likely to change.

Example

{
    "bot": {
        "services": [
            {
                "base_url": "http://hostname.domain2.com",
                "interface": 2,

            }
        ],
        "user_id": 37
    },
    "id": 0,
    "op": "update",
    "type": "realm_bot"
}

        "user_id": 35
    },
    "id": 1,
    "op": "remove",
    "type": "realm_bot"
}

realm_bot op: delete

    },
    "id": 1,
    "op": "delete",
    "type": "realm_bot"
}

realm op: update

The simpler of two possible event types sent to all users in a Zulip organization when the configuration of the organization (realm) has changed.

Often individual settings are migrated from this format to the realm/update_dict event format when additional realm settings are added whose values are coupled to each other in some way. The specific values supported by this event type are documented in the realm/update_dict documentation.

A correct client implementation should convert these events into the corresponding realm/update_dict event and then process that.

  • 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.

  • property: string

    The name of the property that was changed.

  • value: string | boolean | integer

    The new value of the property.

  • extra_data: object

    Object containing extra data related to the changed property.

    • upload_quota: integer

      Note: Only present if changed property is plan_type.

      The new upload quota for the Zulip organization.

Example

{
    "id": 0,
    "op": "update",
    "property": "disallow_disposable_email_addresses",
    "type": "realm",
    "value": false
}

realm op: deactivated

Event sent to all users in a Zulip organization when the organization (realm) is deactivated. Its main purpose is to flush active longpolling connections so clients can immediately show the organization as deactivated.

Clients cannot rely on receiving this event, because they will no longer be able to authenticate to the Zulip API due to the deactivation, and thus can miss it if they did not have an active longpolling connection at the moment of deactivation.

Correct handling of realm deactivations requires that clients parse authentication errors from GET /events; if that is done correctly, the client can ignore this event type and rely on its handling of the GET /events request it will do immediately after processing this batch of events.

  • 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.

  • realm_id: integer

    The ID of the deactivated realm.

Example

{
    "id": 0,
    "op": "deactivated",
    "realm_id": 2,
    "type": "realm"
}

restart

Event sent to all the users whenever the Zulip server restarts.

Specifically, this event is sent whenever the Tornado process for the user is restarted; in particular, this will always happen when the Zulip server is upgraded.

Clients can use this event to know when they should get a new event queue after a server upgrade. Clients doing so must implement a random delay strategy to spread such restarts over 10 minutes or more to avoid creating a synchronized thundering herd effect.

  • 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.

  • zulip_version: string

    The Zulip version number, in the format where this appears in the server_settings and register responses.

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

  • zulip_merge_base: string

    The Zulip merge base number, in the format where this appears in the server_settings and register responses.

    Changes: New in Zulip 5.0 (feature level 88).

  • zulip_feature_level: integer

    The Zulip feature level of the server after the restart.

    Clients can safely avoid refetching their state and creating a new event queue when the API feature level has not changed, or when they know the specific feature level change is not relevant to the client (E.g. it just adds a new endpoint that the client doesn't use).

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

  • immediate: boolean

    Whether the client should fetch a new event queue immediately, rather than using a backoff strategy to avoid thundering herds. A Zulip development server uses this parameter to reload clients immediately.

  • server_generation: integer

    The timestamp at which the server started.

Example

{
    "id": 0,
    "immediate": true,
    "server_generation": 1619334181,
    "type": "restart",
    "zulip_feature_level": 57,
    "zulip_merge_base": "5.0-dev-1646-gea6b21cd8c",
    "zulip_version": "5.0-dev-1650-gc3fd37755f"
}

realm op: update_dict

The more general of two event types that may be used when sending an event to all users in a Zulip organization when the configuration of the organization (realm) has changed.

Unlike the simpler realm/update event format, this event type supports multiple properties being changed in a single event.

  • 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.

BAD_EVENT_QUEUE_ID errors

This error occurs if the target event queue has been garbage collected. A compliant client will handle this error by re-initializing itself (e.g. a Zulip web app browser window will reload in this case).

See the /register endpoint docs for details on how to handle these correctly.

The following is the error response in such case:

{
    "code": "BAD_EVENT_QUEUE_ID",
    "msg": "Bad event queue id: fb67bf8a-c031-47cc-84cf-ed80accacda8",
    "queue_id": "fb67bf8a-c031-47cc-84cf-ed80accacda8",
    "result": "error"
}
