Connectivity APIs

The Nylas Connectivity APIs let you connect to any email, calendar, or contact provider with one integration. You can bypass building an integration for every provider and use a single connection.

The Connectivity APIs include:

  • Email
  • Calendar
  • Contacts


The Email API gives you real-time bi-directional sync with your provider. Send messages, create drafts, add email attachments, and much more.
