Limits & Quotas

  • Rate limits: Google Shopping Content API has per-project and per-user quotas managed via the Google Cloud Console. Default is approximately 7,000 requests per 100 seconds per project.
  • Error model: Non-2xx responses and timeouts are caught and returned as success=False + error rather than raising.
