Feature Description

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

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 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.

Callback Triggering Scenarios

An app user uses the client to initiate a request for adding a user to the blocklist.
The app backend initiates a request for adding a user to the blocklist through the RESTful API.

Callback Triggering Time

The callback is triggered when the Chat backend receives a request for adding a user to the blocklist and successfully adds the user to the blocklist.
