FAQ

Questions about Cancel Booking.

What does the Cancel Booking action do in Cal.com?

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.

Can I use dynamic inputs from earlier workflow nodes?

Yes. Any field on this action can pull values from upstream nodes, whether that's a form response, a trigger payload, an AI output, or a lookup result.

What happens if Cal.com returns an error?

The run history shows the failed step with its input and the error message Cal.com returned, so you can fix the input and run the workflow again. Automatic retries are built into HTTP steps only, where you can also set your own retry count and delay.

Does Cancel Booking support batch operations?

Run Cancel Booking inside a loop to process each item in an array. TinyCommand does not throttle calls for you, so for large arrays add a Delay step if you need to stay within Cal.com's rate limits.
