One API, All The Calendars

Cronofy Calendar API for developers

Calendar integration is hard.
So we've made it easy.

Each platform has its own data models and authentication flows.

Keeping track of changes is a headache.

Handling users' personal data is onerous.

We've fixed all of that.

Cronofy Calendar API

Key Features

Cronofy supports all calendars

Support all calendars not just the easy one

Google calendars are relatively easy to integrate with but inevitably your users aren't only Google users.

Thanks to a common data model and with Cronofy handling authentication and authorisation flows for all calendars, you can focus on your app.

No more maintenance overhead of keeping up with the latest changes to calendar services.

Cronofy interacts with calendars

No more public iCal feeds

iCal feeds are simple to create but awkward to subscribe to for many users, and rely on security through obscurity.

The Cronofy API interacts directly and securely with your users' calendar accounts to ensure sensitive information is in the right place and up to date.

Web hooks

Receive notifications when events are created, updated, tagged.

We handle the complexity of watching for changes so your app remains simple and just needs to react to what's important.

“The API was brilliant to work with.”
