친구 추가 응답 전

Feature Description

This API is used by the app backend to:
View responses to friend requests in real time.
Block malicious responses to friend requests.

Notes

To enable this callback, you must configure a callback URL and toggle on the corresponding protocol. For more information on the configuration method, see Callback Configuration.
During this callback, 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 the SDKAppID of the app.
For more security considerations, see the Security Considerations section in Third-Party Callback Overview.

Callback Triggering Scenarios

An app user initiates a response to accept or reject a friend request.

Callback Triggering Timing

Chat backend receives a response from an app user to a friend request.
Caution:
Responses initiated via RESTful API calls to friend requests will not trigger the callback.
