Connect a user's mailbox with Nylas hosted OAuth

Short summary

Nylas hosted OAuth streamlines email/calendar authentication across Gmail, Outlook, Yahoo, and more through a single standardized flow. The three-step process redirects users to Nylas's consent screen, exchanges an auth code server-side, and returns a grant_id for subsequent API calls. The nylas CLI enables rapid test account connection without building full OAuth callback handlers.

• •Unified OAuth flow across multiple email providers (Google, Microsoft, Yahoo, iCloud, Exchange, IMAP) with consistent grant_id identifiers
• •Three-step authorization: browser redirect to Nylas auth, provider consent handling, and server-side code exchange for authenticated grant
• •CLI tool (nylas auth login) accelerates development by connecting test accounts without OAuth callback infrastructure
