# METHOD_NOT_ALLOWED

> The endpoint exists, but not with this HTTP method.

`405 Method Not Allowed` · type `invalid_request`

**When it happens**

Reserved. Today, a request with an unsupported method on an existing path gets a `405` with no JSON body rather than this error.

**What to do**

Check the method against the [API reference](/api-reference/introduction): `POST` to create, `GET` to read.

<Note>No endpoint returns this code today. It is registered so that integrations can handle it when it appears.</Note>

See all [error codes](/errors), or how to [handle errors](/guides/errors).
