description: A booking moved. Exactly one event — never a cancelled/created pair — and the payload carries the previous time.
- event: booking.cancelled
description: Cancelled by the customer, by you, or by the system when payment was not completed.
- event: booking.no_show
description: You marked the booking as a no-show.
