After the Seat List Is Changed

Feature Overview

The app backend can view microphone position list change messages in real-time through this callback.

Notes

To enable the callback, a callback URL must be configured and the switch corresponding to this callback protocol activated. For configuration methods, see Third-party Callback Configuration document.
During this callback, the Room 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.

Scenarios that may trigger this callback

App user mutes/unmutes microphone.
Operate microphone position lock.

Callback Trigger Time

After microphone position information changes.
