Real-time webhooks for appointment bookings
A webhook is an automated message Koalendar sends the moment a booking is made, canceled, or rescheduled. It posts the booking details to a URL you choose, so your own systems update in real time.
Native webhook integration
How webhooks work with appointment booking software
Koalendar appointment booking webhooks keep your systems up to date without waiting for someone to copy information manually. Add the URL where you want to receive booking data, and Koalendar sends a real-time notification whenever someone makes, cancels, or reschedules an appointment. Your system gets the booking details as JSON, ready for your own workflows and automations.

A webhook is an automated HTTP request the software sends when an event happens. In Koalendar, each new booking, cancellation, or reschedule triggers a POST to a URL you set, carrying the booking details as JSON.
A new booking, a cancellation, and a reschedule. Each sends the relevant details to your endpoint.
The booking's details: who booked, the event type, and the time, sent as JSON. Koalendar documents the exact fields in its webhook guide.
