-Notice how the first value required header `"x-api-key"` has been extracted and can be retrieved using `conn.assigns[:api_key]`. An alternative is to use `Plug.Conn.get_req_header/2` to get all the values associated with a given header.

-If the header is missing or set to `nil` the status code, a status code of 400 (bad request) will be returned before the plug pipeline is halted. Notice that the function specified as a callback needs to be a public function as it'll be invoked from another module.

 Lastly, it's possible to extract multiple headers at the same time.
