When an appointment is deleted from a calendar — whether by a staff member, an automation, or a contact cancelling through a booking page — HoopAI sends an AppointmentDelete event to all configured webhook endpoints. Use this event to cancel corresponding entries in external systems, release reserved resources, or log the removal for auditing purposes.
