HTTP 405 Method Not Allowed — What It Means & How to Fix It
Error4xx client error
Overview
The HTTP 405 Method Not Allowed status code indicates the HTTP method used in the request is not supported for the target resource.
Key Details
- The server must include an Allow header listing the supported HTTP methods.
- For example, trying to POST to a read-only endpoint that only supports GET.
- This is different from 501 Not Implemented, which means the server does not support the method at all.
- Common when APIs have different methods for different operations on the same URL.
Common Causes
- Sending a POST request to an endpoint that only accepts GET.
- Using PUT or DELETE on a resource that does not support modification.
- API version mismatch where supported methods have changed.
- Incorrect HTTP method in client code or form configuration.
Steps
- 1Check the Allow header in the response to see which methods are supported.
- 2Review the API documentation for the correct HTTP method.
- 3Verify your client code is using the intended HTTP method.
- 4If using forms, ensure the method attribute is correct.
- 5Check if the endpoint URL is correct for the operation you intend.
