207207 Multi-Status
The response provides status for multiple independent operations in a single response (WebDAV).
405The HTTP method used is not supported for the requested resource.
You sent a request using an HTTP method (GET, POST, PUT, DELETE, etc.) that the endpoint does not support. For example, sending DELETE to a read-only endpoint, or POST to a GET-only resource.
Check the Allow header in the response for supported methods. Verify you are using the correct HTTP method as specified in the API documentation. Change your request method accordingly.

523Cloudflare could not reach the origin server, typically due to DNS issues.
424The request failed because it depended on another request that failed (WebDAV).
418The server refuses the request because it is, permanently, a teapot. An April Fools' joke from RFC 2324.
203The response has been modified by a transforming proxy and differs from what the origin server sent.
428The server requires the request to be conditional to prevent the 'lost update' problem.
