Frequently Asked Questions

What are some challenges with the Apple Calendar API?

The Apple Calendar API allows developers to interact with the Calendar app on Apple devices such as Macs, iPhones, and iPads. The Apple Calendar API is a complex integration which requires use of a purpose-built Apple SDK and a significant amount of dedicated development time.

With a single connection to Nylas, developers can build applications that integrate Apple Calendar, allowing users to view and manage their events and reminders from within the app. Our API supports various features such as recurring events, alarms, time zones, and invitations.

How does Nylas integrate Apple Calendar, and how can I start integrated?

You can build a connection to Apple Calendar in your application using the Nylas Calendar API. Nylas uses the calendaring extension CalDAV to integrate with Apple Calendar and utilizes a CalDAV-Python package to translate a Python object into the CalDAV standard and vice-versa. Offering an Apple Calendar integration with Nylas gives your application productivity-boosting features such as but not limited to:

  • Bi-directional sync and full CRUD
  • Real-time notifications and with RSVP capabilities
  • Scheduler capabilities
