The Calendar API for SaaS companies and their customers
Read, write, and edit events in your users’ calendars no matter what calendar service they use with our Unified Calendar API. Everything happens in real-time and your users’ data is always secure.
One Calendar API, all the calendars
Build real-time, two-way and secure calendar sync between your applications and your users’ calendars. Our Calendar API connects your software to five major calendar services – Google Calendar, Apple Calendar, Microsoft Office 365, Microsoft Outlook.com, and Microsoft Exchange (including on-premise). This means that you only have to work with one calendar API, not five.
Developers only have to build and maintain one set of connections – Cronofy takes care of the rest. This drastically reduces how long it takes you to add full calendar sync to your applications and software.
Build the scheduling features your users need
Building individual calendar integrations is costly and time-consuming. Your development team also has to deal with ongoing maintenance to ensure that your software works with past, present, and future versions of each calendar service.
We built our calendar API so that you don’t need to worry about any of that. Everything you build will work with all major calendar services.
Agenda View UI Element
We see a lot of our customers build user interface elements to deliver scheduling with Cronofy APIs. So we decided to build a suite of UI Elements for you.
The Agenda View UI Element leverages our Unified Calendar API to sync the UI with the connected calendar. The Agenda View displays a single-day period and only shows time slots for existing events.
The primary view is a column of event summaries, with the ability to navigate to the next or previous day. Clicking an event reveals the full details for that event.

We tell you when changes happen
With the Cronofy Unified Calendar API, you can set up push notifications to notify your application whenever something changes in a user’s calendar. We have solved the real-time calendar sync challenge to ensure your application is always up-to-date.
Your users don’t have to wait 24 hours for an event to appear in their application after they add it to their calendars. With Cronofy’s calendar sync technology, you can help your users prevent double-booking and reduce the amount of time they spend rescheduling events.
Don't worry, we keep your data safe
Protecting your data (and that of your users) is paramount to us. That’s why we use OAuth2 to control access and security to your users’ calendars. You can also choose to host your data in the US or Germany. Both data centers are fully GDPR compliant and adhere to our stringent data security policies.
