Feature Description

The app backend uses this callback to monitor group dismissal in real time, including recording group dismissal information in real time (for example, recording a log or synchronizing the information 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

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

Callback Triggering Time

The callback is triggered after a group is dismissed.
