Calendar APIs

Programmatic interfaces to sync, create, and manage scheduling data across Google, Outlook, and Apple platforms.

Calendar APIs bridge the gap between custom applications and established scheduling platforms like Google Calendar (with over 1 billion users) and Microsoft Outlook. Developers use these RESTful endpoints to automate event creation, manage attendee availability, and handle complex time zone conversions. Most integrations utilize OAuth 2.0 for security and support standard formats (iCalendar and CalDAV) to maintain data consistency. By leveraging unified providers like Nylas or Cronofy, teams can consolidate fragmented data from various sources into a single stream for CRM tools, booking engines, or HR portals.
