Google still requires a registered OAuth client in Google Cloud Console (this is how Google identifies your app). You do not need to put those values in .env: paste them here once per server; they are stored under data/google_oauth_client.json. After that, anyone who uses this app can click Connect on the CRM and sign in with their Google account in the browser.

1. Redirect URI in Google Cloud

Create an OAuth client of type Web application. Under Authorized redirect URIs, add this URL exactly:

http://127.0.0.1:8011/integrations/google/oauth2callback

2. Save credentials here

Client ID

Client secret

Save OAuth client Back to CRM
