How to get custom headers from a request in Laravel 5?

Question

API

Testing API for mobile applications using Postman. I'm trying to send tokens in headers, but there are no headers in the request object. If I send any standard content-type or accept headers, then I can get their values, but custom headers are not visible at all: neither their keys nor values.
For example, I send headers like this:

Then, I output them:

<?php 
namespace App\Http\Controllers\API\MobileApp;

use Illuminate\Http\Request;
use App\Http\Controllers\Controller;

class OrdersController extends Controller
{
    /**
     * Display a listing of the resource.
     *
     * @param  \Illuminate\Http\Request  $request
     * @return \Illuminate\Http\Response
     */
    public function index(Request $request)
    {
        dd( $request->headers);
    }
}

As a result, I get all the headers, except for tokens:

Maybe I don’t know something, and such headers, in principle, cannot be transmitted? Or is there some kind of filter in Laravel that doesn't allow passing non-standard headers? Thanks in advance for your replies.

App-Token, App-Auth, not App_Token, App_Auth.
