Invoke a Callback After Modifying Group Profiles

Last updated: 2020-07-01 17:39:32

    Feature Description

    The app backend uses this callback to monitor changes to group information (including the group name, group introduction, group notification and profile photo) in real time, including recording the changes of group information in real time (for example, recording a log or synchronizing the changes to other systems).

    Precautions

    • 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

    Content that may trigger the callback

    Group information includes basic group information and group-specific custom fields.
    Currently, this callback may be triggered when the group name, group introduction, group notification, or profile photo URL is modified. This callback is not triggered when other basic group information is modified.

    Callback triggering scenarios

    • An app user modifies group information through a client.
    • The app admin modifies group information through a RESTful API.

    Callback Triggering Time

    The callback is triggered after basic group information is modified.
