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 workflow pauses on the failed node, the error message is captured in the run log, and you can retry the run with one click. Auto-retry policies are configurable per workflow with exponential backoff up to 5 attempts.

Does Cancel Appointment support batch operations?

Yes. Run Cancel Appointment inside a Loop node to process arrays. Tiny Command handles Acuity Scheduling's rate limits automatically so you don't have to throttle manually.
