The table below contains the room-related events, as well as the purpose of each event. If you want to execute actions based on room events, you can use any of the events mentioned below as an event interface.

Interface	Description
IPostRoomCreate	Handler after a room is created.
IPostRoomDeleted	Handler after a room is deleted.
IPostRoomUserJoined	Event interface that allows an app to register as a handler of the IPostRoomUserJoined event. This event is triggered after a user successfully joins a room. This event does not allow an app to prevent any action from happening. For that, see the IPreRoomUserJoined interface.
IPostRoomUserLeave	Event interface that allows an app to register as a handler of the IPostRoomUserLeave event. This event is triggered after a user successfully leaves a room. This event does not allow an app to prevent any action from happening. For that, see the IPreRoomUserLeave interface.

IPreRoomCreateModify	​​Handler called when an app wants to modify a room.

IPreRoomUserJoined	Event interface that allows an app to register as a handler of the IPreRoomUserJoined event. This event is triggered prior to a user successfully joining a room.

For that, check the IPreRoomCreate event.
