Authentication & security

  • Primary auth: OAuth 2.0
  • Also supports: API key
  • Security review: Required
  • Google's OAuth verification and CASA security assessment required for sensitive/restricted scopes.
  • Listing requires both OAuth verification (consent-screen and data-use review, with a possible demo video and CASA security assessment for sensitive scopes) and a separate Marketplace app review of branding, scopes, and UX — budget roughly 2-3 weeks, longer if a security assessment is triggered.
  • Per-project and per-user quotas across Workspace APIs, managed via Google Cloud Console.
