# METHOD_NOT_ALLOWED

> A refusal with HTTP 405 that carries no more specific code.

Its problem `type`: `https://developers.tassyir.io/errors/method-not-allowed`; its `title`: Method not allowed.

## What to do

Call the operation with the method its reference names.

## Answered by

The code of a refusal with HTTP 405 that carries no more specific code. Any operation may answer it.

A hosted app's `ctx.props.TASSYIR` binding also answers it itself, before the call is sent ([Tassyir Hosting](/guides/tassyir-hosting#call-the-admin-api)).

The shape of every problem, and how `@tassyir/app` reports it: [Errors](/guides/errors).
