Frequently Asked Questions

What is Apple Calendar API?

The Apple Calendar API is a programming interface provided by Apple that allows developers to interact with the Calendar app on Apple devices such as Macs, iPhones, and iPads. 

Using the Apple Calendar API, developers can build applications that integrate with the Calendar app, allowing users to view and manage their events and reminders from within the app. The API supports various features such as recurring events, alarms, time zones, and invitations.

How do I get started integrating with the Apple Calendar API?

To use the Apple Calendar API, developers need to first obtain an access token by registering their app with Apple’s Developer portal and following the authentication and authorization process. Once authenticated, developers can then make requests to the API endpoints using HTTP requests with JSON payloads.

How do I integrate Apple Calendar with other apps or services?
