Troubleshooting

"Domain-wide delegation not configured"

Double-check that you entered the Client ID and OAuth scopes exactly as shown above. Scopes must be comma-separated with no spaces.

"403 Forbidden" errors

The OAuth scopes may not match. Delete the delegation entry and re-add it with the exact scopes.

Can't find API controls

Make sure you're signed in as a Super Admin. Regular admins may not have access to this setting.
