Feature Description

The app backend uses this callback to monitor information about users added to the blacklist 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 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 uses the client to initiate a request for adding a user to the blacklist.
  • The app backend initiates a request for adding a user to the blacklist through the RESTful API.

Callback Triggering Time

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

API Description

In the following example, the callback URL configured in the app is https://www.example.com.
