After the Seat List Is Changed

Feature Overview

The App backend can view 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.
The direction of the callback is from the Room backend to the App backend via an HTTP POST request.
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

Pick App user on the seat/Kick user off the seat.
Lock the seat position.

Callback Trigger Time

After the seat position information changes.
