# API Reference

The full reference for the Cronofy API.

Start with [API fundamentals](https://docs.cronofy.com/api-reference/fundamentals/index.md) for
the conventions every request follows, and
[Authorization & authentication](https://docs.cronofy.com/api-reference/authorization/index.md)
for how your application gets access to calendars. The other sections group the
endpoints by capability: managed scheduling & rescheduling, modular
availability & calendar control, and conferencing & transcription.

For how the endpoints fit together to build a feature, see
[Build with Cronofy](https://docs.cronofy.com/developers/index.md). You can also explore the API
with [Postman](https://docs.cronofy.com/developers/getting-started/postman/index.md).
