- `PATCH` - Very similar to `PUT` but makes a partial update on a resource

- `DELETE` - Deletes resource or related component

- `HEAD` - Retrieve response headers identical to those of a GET request, but without the response body.

- `CONNECT` - Establishes a tunnel to the server identified by the target resource

- `OPTIONS` - Describe the communication options for the target resource

- `TRACE` - Performs a message loop-back test along the path to the target resource

- `` - Some APIs use custom request methods such as `LIST`. Type in your custom methods.
