PayU Express Checkout Payment Gateway integration in PHP Laravel ecommerce website

Integrating PayU Express Checkout in a Laravel eCommerce platform allows customers to pay quickly and securely using a modern checkout interface provided by PayU. The Express Checkout supports multiple Indian payment methods such as credit and debit cards, UPI, net banking, and digital wallets. With a responsive design and a fast, mobile-optimized UI, this method enhances the overall shopping experience and increases conversion rates. More importantly, it is fully PCI-DSS compliant, meaning customer data remains safe and secure throughout the transaction process. If you're running an online store using Laravel, integrating a trusted payment gateway like PayU can significantly boost trust and reduce cart abandonment.

We will cover the full integration process including backend configuration for merchant credentials, dynamic form generation, AJAX-based submission, client-side SHA512 signature hashing for added security, and handling success and failure responses effectively.

2. PayU Merchant Account Setup

Login to PayU Merchant Dashboard and obtain your API Key and Salt for both test and live environments. Under developer settings, configure the Success URL and Failure URL.

3. Payment Gateway Settings Model

5. Define the Route

Add this to your web.php:

6. Blade View and JavaScript Integration

7. Secure Your Hashes

The hash generation should ideally be done on the server side for better security. If using on the front-end, make sure to implement extra validation on the backend response.

8. Payment Response Handling

PayU redirects to surl or furl after payment. Your Laravel route should handle both and mark the order status accordingly.
