Laravel GuzzleHttp issue

I need to use and API from example.com I use Laravel as a framework and to get data with API in their docs I see this:

  curl http://ift.tt/2riu0gD ^
 -H "Authorization: Bearer eyJ0ehsagdasjhgdashdgaOiJIUzI1NiJ9.eyJpc3Msjhdshjdasd7676N5c3RlbXMuY29tIn0.DBR5UPxxxxxxzxzxzxzxzxzxzxyzxyzxyzxyzyxzyxyzxyxxWQ_BkS1mzxw" ^
 -d VisitDate=2017-05-08 ^
 -d PartySize=2 ^
 -d ChannelCode=ONLINE

What I try to do is:

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;

use App\Http\Requests;
use App\Http\Controllers\Controller;
use GuzzleHttp;

class TestController extends Controller
{
    /**
     * Display a listing of the resource.
     *
     * @return \Illuminate\Http\Response
     */

    public function test()
    {

$client = new GuzzleHttp\Client();

$res = $client->request('GET','http://ift.tt/2rRzzj0', [
    'headers' => [
        'Authorization' => 'Bearer eyJ0ehsagdasjhgdashdgaOiJIUzI1NiJ9.eyJpc3Msjhdshjdasd7676N5c3RlbXMuY29tIn0.DBR5UPxxxxxxzxzxzxzxzxzxzxyzxyzxyzxyzyxzyxyzxyxxWQ_BkS1mzxw',
    ],
    'form_params' => [
        'VisitDate' => '2017-05-24',
        'PartySize' => '2',
        'ChannelCode' => 'ONLINE',
    ],
]);

// You need to parse the response body
// This will parse it into an array
$res = json_decode($res->getBody(), true);

dd ($res);

    }


    public function index()
    {
        //
    }

    /**
     * Show the form for creating a new resource.
     *
     * @return \Illuminate\Http\Response
     */
    public function create()
    {
        //
    }

    /**
     * Store a newly created resource in storage.
     *
     * @param  \Illuminate\Http\Request  $request
     * @return \Illuminate\Http\Response
     */
    public function store(Request $request)
    {
        //
    }

    /**
     * Display the specified resource.
     *
     * @param  int  $id
     * @return \Illuminate\Http\Response
     */
    public function show($id)
    {
        //
    }

    /**
     * Show the form for editing the specified resource.
     *
     * @param  int  $id
     * @return \Illuminate\Http\Response
     */
    public function edit($id)
    {
        //
    }

    /**
     * Update the specified resource in storage.
     *
     * @param  \Illuminate\Http\Request  $request
     * @param  int  $id
     * @return \Illuminate\Http\Response
     */
    public function update(Request $request, $id)
    {
        //
    }

    /**
     * Remove the specified resource from storage.
     *
     * @param  int  $id
     * @return \Illuminate\Http\Response
     */
    public function destroy($id)
    {
        //
    }
}

Now when I try to test i get:

BadMethodCallException in functions.php line 324:
Unknown method, request

How I can solve ths problem? How to use Guzzle instead cURL with Laravel framework? What is wrong in my code ... I just follow guzzle docs and API docs.
