Yes, but during appointment drag and drop, there are few validations to be done, an API will handle that.
If the request is asynchronous until we get the response from API, the appointment is moved back to the original position and after the response, the appointment is getting moved to the new position.

No need - our drag drop support async finalization, just need to read our docs a bit. Look at https://www.bryntum.com/docs/scheduler/#Scheduler/feature/EventDrag#event-beforeEventDropFinalize
