Pick the Gmail Tool example when you want to:

  • Build an agent that sends transactional or notification emails

  • Learn how OAuth connections work with Google APIs

How connections work

Reminix handles the Google OAuth flow, token exchange, and automatic refresh. Your tool handler receives a valid access token and uses the Gmail API directly.

  1. Add Google OAuth credentials in the Reminix dashboard
  2. Authorize the connection to your Gmail account
  3. Your tool gets fresh tokens on every call
