Hi,
AppWarpS2 provide support for RPC(Remote Procedure Call) at Zone and Room level.So you can define you own function on AppWarpS2 to use it as a RPC.
In your case you can use such RPC function that you have defined at Zone or Room level in AppWarpS2, and update information on database and can send response to user.
You can go through with the documentation that will help you in integration.
Let me know if more queries are concern.
Thanks & Regards
