A CancelledBooking is a read-only snapshot of a booking that was removed from the calendar. When a booking is cancelled, the system preserves its details — resource, coworker, time range, price, and cancellation metadata — so they remain available for reporting and auditing.Cancelled bookings cannot be created or modified through the API; they are generated automatically when an active Booking is cancelled. Use list and get to query cancellation history.The CancellationReason field indicates why the booking was removed. Possible reasons include the customer no longer needing the booking, cost concerns, rebooking for a different time, failure to pay upfront, automated cancellation due to not checking in, and others.
