Booking can send events when an appointment is created, cancelled or rescheduled. These events can trigger a Zap or be delivered to your own webhook URL.
Set up the API key, Zapier connection or webhook URL from the shared Integrations page in bookto. The connection is account-level; the events available to you depend on which tools are enabled for your account. Zapier and webhooks require the Flow plan.
See Connect bookto to Zapier and other tools for the shared setup. For checkout order events, payloads and testing, see Use your own webhook URL.
