Managing Payment Gateway Failures in Magento 2: A Practical Guide

Handling payment gateway failures in Magento 2 is essential for maintaining a smooth shopping experience. Failed transactions can frustrate customers, leading to abandoned carts and lost sales. To manage these failures, Magento provides the Magento\Sales\Api\PaymentFailuresInterface, which allows you to handle errors programmatically and enhance customer experience.

Here’s how to effectively handle payment gateway failures in Magento 2.

Steps to Manage Payment Gateway Failures

Integrate the PaymentFailuresInterface

Magento includes the PaymentFailuresInterface to manage errors that occur during payment transactions. This interface’s handle() method is specifically designed to address payment failures.

namespace YourVendor\PaymentFailure\Model;

use Magento\Sales\Api\Data\OrderInterface;

use Magento\Sales\Api\PaymentFailuresInterface;

use Magento\Framework\Exception\LocalizedException;

class PaymentFailure

{

private $paymentFailures;

public function __construct(PaymentFailuresInterface $paymentFailures)

{

$this->paymentFailures = $paymentFailures;

}

public function placeOrder(OrderInterface $order)

{

try {

$order->place();

} catch (LocalizedException $exception) {

$this->paymentFailures->handle(

(int)$order->getQuoteId(),

$exception->getMessage()

);

throw $exception;

}

Explanation:

getQuoteId(): Refers to the ID of the shopping cart or quote.
Error Handling: Captures any exception that occurs during order placement.

Customizing Error Messages

Use the second parameter of the handle() method to provide a clear and concise error message. This improves communication with customers when a payment fails.

$this->paymentFailures->handle(

(int)$order->getQuoteId(),

__($errorMessage),

$checkoutType = 'onepage'

);

Parameters in handle():

Parameter	Description
Quote ID	Unique identifier of the cart associated with the order.
Error Message	Descriptive message indicating the failure reason.
Checkout Type	Specifies the checkout type, e.g., 'onepage'.

Benefits of Handling Gateway Failures

Reduces abandoned carts by providing clear guidance on errors.
Ensures a smoother checkout process by addressing issues at the code level.
Improves the overall customer experience.

Handling payment gateway errors is not just a technical necessity—it’s a customer service imperative. Implementing proper error handling, like using the PaymentFailuresInterface, ensures your Magento store remains reliable and user-friendly..
