After A One-to-One Message Is Recalled

最終更新日:2024-02-07 17:30:51

    Feature Description

    This API is used by the app backend to view the recalls of one-to-one messages in real time.

    Notes

    To enable this callback, you must configure the callback URL and enable the corresponding switch for this callback. For more information on the configuration method, see Callback Configuration.
    During this callback, the IM backend initiates an HTTPS 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 the SDKAppID of the app.
    For more security considerations, see the Security Considerations section in Third-Party Callback Overview.

    Callback Trigger Scenarios

    An app user recalls a one-to-one message on the client.
    An app admin recalls a one-to-one message by calling the admin_msgwithdraw API.

    Callback Trigger Timing

    After a one-to-one message is recalled successfully
