# Google Callback

> Complete the Google OAuth flow for a specific Google service.

The frontend calls this after Google redirects back to the callback page
with a temporary ``code``. This endpoint:
  1. Validates the requested service
  2. Validates the CSRF ``state`` against the server-side store
  3. Exchanges the code for access + refresh tokens
  4. Fetches the Google user profile
  5. Upserts the integration row with provider=service
  6. Resets the in-memory token state for that service module
  7. Returns basic integration info (never the raw token)
