Programmatically cancels a booking. Cal.com sends the configured cancellation email. Useful for "host out sick → bulk-cancel today's bookings with the right reason" workflows.
What inputs does Cancel Booking require?
Required: Booking UID. Every input accepts a static value or a variable from any upstream node in your workflow.
