This includes requests with invalid API keys or expired authentication tokens. Before the rollout, update any clients, monitoring, or automation that check for 403 to detect authentication failures. These should handle 401 responses instead. Requests with valid credentials but insufficient permissions will continue to return 403 Forbidden . For more information, see our docs .
