Power two-way calendar sync with a unified Calendar API
Unified Calendar API
Integrate your customers' calendars with one API
Connect to Google, Microsoft, Apple, and more to read, write, and update events as they change, or use free/busy access only when full calendar sync isn’t required.
Your users authorize through a flow branded for your app, while Cronofy handles authorization and syncing as an intermediary, so you don’t need to build or maintain separate integrations for each provider API.
Webhooks
Keep in sync with real-time push notifications
Cronofy's sync engine monitors your users' calendars continuously and notifies your app the moment something changes, based on rules you set.
Events your app creates are tracked separately from the user's own, so you're only alerted to what matters.
Integrated Conferencing
Add conferencing to calendar events
Cronofy manages every connection so you don't have to. Automatically generate conferencing links for calendar events, with built-in support for Google Meet and Microsoft Teams, or let users connect their own Zoom, GoTo, or Webex accounts too.
Bulk Onboarding
Automatically onboard users with Enterprise Connect
Onboard enterprise customers fast with Enterprise Connect. A single approval from a domain admin connects calendars automatically, with nothing for individual users to do.
Built on a single, compliant infrastructure backed by 99.99% uptime
We've never forced a breaking API upgrade. Integrate our Calendar API once, then expand into new capabilities as you need them, without re-platforming or migrating your integration later.
When a calendar provider has an outage, our Sync Engine serves cached data so your users keep seeing accurate availability and bookings keep going through.
Host your users' data in the right region for them
Cronofy operates six global data centers so you can choose the location that meets your customers' needs.
We believe that data security and location controls should be available to anyone so you can operate in one or all six on any of our API pricing plans for no extra charge.
