The Cal.com API is a REST-styled API that gives control over almost the entire Cal.com platform by providing all the resources available to our customers, exposed as simple HTTP endpoints. Whether you need to create an event type, modify it, fetch it, or remove it from your account, you can do all that with simple API requests. This isn't restricted to event types alone. You can do it all with the other resources as well, such as, bookings, availabilities, integrated calendars, schedules, team memberships, payments and much more without ever need to use the UI.
The Cal.com API is organized around REST. Our API has predictable resource-oriented URLs, accepts JSON-encoded request bodies, returns JSON-encoded responses, and uses standard HTTP response codes, authentication, and verbs.
