Nylas Documentation

Nylas Connect is one API for email, calendar, contacts, and scheduling across every provider. Add Notetaker for meeting transcription, and Agent Accounts for mailboxes your AI agents own.

Each account you connect becomes a grant: the same endpoints work across Gmail, Microsoft 365, iCloud, Yahoo, Exchange, and IMAP. Requests take an API key and a grant ID, against api.us.nylas.com or api.eu.nylas.com.
