A booking lands in Calendbook while you are serving a customer or away from your desk. The appointment is recorded, but the person who booked it may still need confirmation, directions or a reminder about what happens next. Zapier can take Calendbook’s New Booking event and start a Mobile Message SMS, so the response does not depend on someone checking the calendar.

New Booking can send a confirmation containing the appointment details and contact information collected during booking. Reschedule Booking can send an updated time, helping reduce confusion when plans change. You can map the guest’s phone number and personalise each plain text message with the available booking fields. This is a one-directional Zapier connection, not a native integration or a two-way synchronisation between calendars and messages. Calendbook triggers the selected Mobile Message action, while you decide the wording and data passed in Zapier. That gives booking teams a practical way to acknowledge calendar activity soon after it occurs.
