Parameters

Response

Return values

• stream: object

  Object containing basic details about the 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.

    Changes: New in Zulip 2.1.0.

  • 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.

    Is null for streams with no message history.

    Changes: New in Zulip 2.1.0.

  • 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: integer

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

    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 stream 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 stream 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.
