What is HTTP 405 Method Not Allowed?

The 405 (Method Not Allowed) status code indicates that the method received in the request-line is known by the origin server but not supported by the target resource. The response must include an Allow header listing the supported methods. For example, an API endpoint might only accept GET and POST, and respond with 405 for PUT or DELETE requests.

Common Use Cases

  • POST request to a read-only endpoint
  • PUT request to an endpoint that only accepts GET
  • API endpoint with restricted HTTP methods
