Feature Description

The app backend uses this callback to view information about friends added by users in real time.

Notes

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 Chat 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.
