Invoke a Callback After Deleting a Blacklist

Last updated: 2020-03-11 16:19:50


Feature Description

Through this callback, the app backend can monitor the deletion of user blacklists in real time.


  • 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 a client to initiate a blacklist deletion request.
  • The app backend initiates a blacklist deletion request through the RESTful API.

Callback Triggering Time

The callback is triggered after the IM backend receives a blacklist deletion request and successfully deletes the blacklist.
