45For Google Workspace data (Drive, Calendar, Gmail, Docs), the service account needs domain-wide delegation configured in your Google Admin console with the matching API scopes.

45For Google Workspace data (Drive, Calendar, Gmail, Docs), the service account needs domain-wide delegation configured in your Google Admin console. In the service account's domain-wide delegation entry, list every scope you entered in **Scopes**, or `https://www.googleapis.com/auth/cloud-platform` if you left **Scopes** empty. Google's guide is at [developers.google.com/identity/protocols/oauth2/service-account](https://developers.google.com/identity/protocols/oauth2/service-account#delegatingauthority).
