Interkassa integration problem?

Question

Laravel

The site is written in laravel, I connect the checkout according to the documentation, payments go through, but the checkout does not seem to get to the interaction url, because if you specify the request method for the interaction url GET in the checkout settings, and in web.php POST, then an error should occur which is not.

// url взаимодействия 

 public function result(Request $request) 
    {
        $dataSet = $request->all();

        if(!$dataSet)
            exit('error 1');
        
        $key = 'ключ тестовой кассы';
    
        unset($dataSet['ik_sign']); 
        ksort($dataSet, SORT_STRING);
        array_push($dataSet, $key); 
        $signtring = implode(':', $dataSet);
        $sign = base64_encode(md5($signString, true)); 
    
        if($sign != $request['ik_sign'])
            exit('error 2');
        
        $order = new Order;
        $cart = \Cart::getContent();
        $order_number = time();
   
       return $order->addOrder($order_number, $cart);
    }

<form id="payment" name="payment" method="post" action="" enctype="utf-8">
  <input type="hidden" name="ik_co_id" value="id кассы"/>
  <input type="hidden" name="ik_pm_no" value="{{ time() }}"/>
  <input type="hidden" name="ik_am" value="{{ $total }}"/>
  <input type="hidden" name="ik_cur" value="RUB"/>
  <input type="hidden" name="ik_desc" value="Payment Description"/>
  <input type="submit" value="Pay">
</form>

View logs? Disable csrf check for post request from interkassa?
