Callback After the Group Owner Changed

Last updated: 2024-05-14 14:30:33

    Feature Overview

    The app backend can use this callback to view group owner change information in real-time. The app backend can perform operations such as data synchronization based on this callback.

    Notes

    To enable the callback, you must configure a callback URL and toggle on the corresponding protocol switch. For detailed configuration methods, see Third-party Callback Configuration document.
    During this callback, the Chat backend initiates an HTTP POST request to the app backend.
    After the callback request is received, the app backend must check whether the SDKAppID contained in the request URL is consistent with its own SDKAppID.
    For other security-related matters, please refer to the Webhook Overview - Security Considerations document.

    Scenarios That May Trigger This Callback

    An app user successfully transfers the group owner via the client.
    An app administrator successfully transfers the group owner via the REST API.

    Callback Trigger Time

    After you successfully transferring the group owner.
