   $errorStatus = YandexKassaHelper::STATUS_BAD_REQUEST;

   if ($helper->isCheckOrderAction()) {
       $errorStatus = YandexKassaHelper::STATUS_PAYMENT_REJECTED;
   }

   try {
       $helper->parseRequest($_POST);
   } catch (AuthorizationErrorException $e) {
       // ... handle this exception ...

       return $this->xmlResponse($helper->buildResponse(null, $e->getMessage()));
   } catch (BadRequestException $e) {
       // ... handle this exception ...

       return $this->xmlResponse($helper->buildResponse(null, $e->getMessage()));
   } catch (\Exception $e) {
       // ... handle this exception ...

       return $this->xmlResponse($helper->buildResponse($errorStatus));
   }

   try {
       $payment = $helper->getPayment();

       // ... do some validation using $payment data ...

       if ($helper->isPaymentAvisoAction()) {
           // ... Mark this payment as settled in your system ...
           // ... log successful transaction, if needed ...
           // ... notify user of successful transaction. if needed ...
       }

       return $this->xmlResponse($helper->buildResponse(/* successful by default */));
   } catch (\Exception $e) {
       // ... handle this exception ...

       return $this->xmlResponse(
           $helper->buildResponse(YandexKassaHelper::STATUS_PAYMENT_REJECTED, $e->getMessage())
       );
   }
