How do I cancel an Acuity appointment programmatically?
Short answer: You can cancel appointment in Acuity Scheduling by hand from its own interface, but it won’t repeat itself. On TinyCommand, add the Acuity Scheduling Cancel Appointment action to a workflow, map its 2 inputs from any upstream app, and it runs automatically every time the trigger fires. No code, and a free tier to start.

FAQ
Questions about Cancel Appointment.
What does the Cancel Appointment action do in Acuity Scheduling?
Cancels a specific appointment by ID. Acuity sends the configured cancellation email to the client unless you suppress it. Useful for "no-show after 15 minutes → auto-cancel, free the slot" workflows or "practitioner sick → bulk-cancel today" admin automations.
What inputs does Cancel Appointment require?
Required: Appointment ID. 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 Acuity Scheduling returns an error?
The run history shows the failed step with its input and the error message Acuity Scheduling 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 Appointment support batch operations?
Run Cancel Appointment 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 Acuity Scheduling's rate limits.

ActionList Appointments
