I am working on a payment module using Magento 2.3.1. I have already implemented CsrfAwareActionInterface and 2 of its methods (createCsrfValidationException() & validateForCsrf()) in my controller just before execute() function. It redirects me to the payment gateway website successfully and makes the purchase.

However, I have set this below URL as my Return URL:


But Magento 2.3.1 redirects to the homepage and throws Invalid Form Key. Please refresh the page error. I have tried to search for all possible solutions but to no avail.

I have already confirmed it from the payment gateway side, and it is perfectly returning to my mentioned above URL. I am not sure that if there's something wrong with Magento 2.3 because before implementing CsrfAwareActionInterface, the code was working correctly on previous Magento 2 versions.

Here is the controller's code:

namespace PayAxis\PayAxisPaymentModule\Controller\Index;

use Magento\Framework\App\CsrfAwareActionInterface;
use Magento\Framework\App\RequestInterface;
use Magento\Framework\App\Request\InvalidRequestException;
use \Magento\Framework\App\Action\Action;
use Psr\Log\LoggerInterface;

class Index extends Action implements CsrfAwareActionInterface
    /** @var \Magento\Framework\View\Result\PageFactory  */
    protected $resultPageFactory;
    private $orderFactory;
    protected $_checkoutSession;
    protected $scopeConfig;

    public $currency;
    public $Amount;
    public $ExpiryTime;
    public $_TxnRefNumber;
    public $_TxnDateTime;
    public $_Description;

    const XML_PATH_ACTIONURL = 'payment/payaxispaymentmethod/actionurl';
    const XML_PATH_MERCHANTID = 'payment/payaxispaymentmethod/merchantid';
    const XML_PATH_PASSWORD = 'payment/payaxispaymentmethod/password';
    const XML_PATH_RETURNURL = 'payment/payaxispaymentmethod/returnurl';
     const XML_PATH_IntegritySalt = 'payment/payaxispaymentmethod/IntegritySalt';
      const XML_PATH_ExpiryHours = 'payment/payaxispaymentmethod/ExpiryHours';

public function __construct(
        \Magento\Framework\App\Action\Context $context,
        \Magento\Sales\Model\Order $salesOrderFactory,
       \Magento\Framework\App\Config\ScopeConfigInterface $scopeConfig,        
        \Magento\Checkout\Model\Session $checkoutSession
        /* array $data = [] */

        return null;

        return true;

        $orderId = $this->_checkoutSession->getLastOrderId();

                               $ExpiryHours = $this->scopeConfig->getValue(self::XML_PATH_ExpiryHours, $storeScope);

Magento 2.3.0: Implement below code to skip the CSRF check on your custom route called outside Magento environment. This implementation does not break core frontend/adminhtml routes


<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager/etc/config.xsd">
    <type name="Magento\Framework\App\Request\CsrfValidator">
        <plugin name="csrf_validator_skip" type="Module\Vendor\Plugin\CsrfValidatorSkip" />


namespace Vendor\Module\Plugin;

class CsrfValidatorSkip
     * @param \Magento\Framework\App\Request\CsrfValidator $subject
     * @param \Closure $proceed
     * @param \Magento\Framework\App\RequestInterface $request
     * @param \Magento\Framework\App\ActionInterface $action
    public function aroundValidate(
        \Closure $proceed,
    ) {
        /* Magento 2.1.x, 2.2.x */
        if ($request->getModuleName() == 'Your_Module_frontName_Here') {
            return; // Skip CSRF check
        /* Magento 2.3.x */
        if (strpos($request->getOriginalPathInfo(), 'Add_Controller_frontName') !== false) {
            return; // Skip CSRF check
        $proceed($request, $action); // Proceed Magento 2 core functionalities

copied from This I hope it will also work for you as well
