Callback After Recalling a One-to-One Message

Last updated: 2021-12-01 16:40:08

    Feature Description

    This API is used by the app backend to monitor 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
