HTTP 405 Method Not Allowed Online

Updated 2026-07-26

HTTP 405 Method Not Allowed means the URL you requested is real and valid, but the HTTP method you used — GET, POST, PUT, DELETE — isn't one that endpoint accepts. The resource exists; you're just addressing it the wrong way.

The fix is almost always in the request itself: check what method the endpoint's documentation expects (a form's method attribute, an API client's verb) and match it exactly. A compliant 405 response also includes an Allow header listing the methods that DO work, which is the fastest way to confirm the fix. For every other status code at once, use the full HTTP Status Codes reference.

// how to use

  1. 1 The code is already looked up below — 405 is pre-filled.
  2. 2 Type any other status code to look that one up instead.
  3. 3 Copy the result, or use the full HTTP Status Codes reference for every code at once.

// faq

Is anything uploaded to a server?
No. The lookup runs entirely in your browser from a built-in table, so nothing you type leaves your machine.
What's the most common cause of a 405?
Sending a POST, PUT, or DELETE to an endpoint that only accepts GET (or vice versa) — often from a form's method attribute being wrong, or an API client hard-coding the wrong HTTP verb.
How is 405 different from 404?
404 means the URL doesn't exist at all. 405 means the URL exists and is valid, but the specific HTTP method you used isn't one it supports — the resource is there, you're just talking to it the wrong way.
Should a 405 response include anything besides the status code?
Per the HTTP spec, yes — a 405 response should include an Allow header listing which methods ARE supported, so a well-behaved client (or a developer debugging) can see the fix immediately.
Can browser caching or a proxy cause a false 405?
Yes — some CDNs or API gateways restrict methods at the edge for security, returning 405 before the request even reaches your application, which can look like an application bug when it isn't.
