Cloudflare Web Analytics - /cdn-cgi/rum endpoint now returns 405 for non-POST requests
UpdateUnverifiedAdded Sep 24, 2026
The /cdn-cgi/rum beacon endpoint now returns 405 Method Not Allowed for non-POST requests instead of 404 Not Found . The response includes an Allow: POST, OPTIONS header per RFC 9110 §15.5.6 ↗ . Previously, sending a GET or other non-POST request to this endpoint returned a 404 , which was misleading because it suggested the endpoint did not exist.
