Callback After a User Leaves a Group

Last updated: 2022-08-22 14:35:41

    Feature Description

    The app backend can use this callback to view users who quit groups in real time, including recording users' quitting information (for example, recording a log or synchronizing the quitting information to other systems).


    • To enable this callback, you must configure the callback URL and toggle on the corresponding protocol. For details on the configuration method, see Third-Party Callback Configuration.
    • Callback direction: the IM backend initiates an HTTP POST request to the app backend.
    • After receiving the callback request, the app backend must check whether the SDKAppID contained in the request URL is consistent with its own SDKAppID.
    • For other security-related issues, see Third-Party Callback Overview: Security Considerations.

    Callback Triggering Scenarios

    • An app user quits a group through the client.
    • An app user removes a member from a group through the client.
    • The app admin removes a member from a group through a RESTful API.

    Callback Triggering Time

    The callback is triggered after a user quits a group or is removed from the group by the group owner or admin.
