Ask any developer, and they'll tell you that integrating your app with the Exchange Calendar API is no easy feat. Decades old technology like WBXML, legacy protocols, and server-specific issues create more problems than they solve.

With the Nylas Calendar API, developers can build apps that seamlessly connect to Exchange Calendars. Nylas sits on top of the Exchange Calendar API (and every other calendar provider) to provide a single point of integration to connect to any calendar service.
