**** Secure PHP Integration for Chinese Payment Gateway (Alipay / WeChat Pay Ready) **** I will implement a clean, modular PHP integration that connects your existing checkout flow to a Chinese payment gateway such as Alipay or WeChat Pay, following the provided API specs end-to-end. The solution will handle token generation, request signing, order submission, and secure callback verification to update your database reliably. On the front-end, I’ll connect your checkout button to trigger the payment flow smoothly, ensuring a seamless user experience without redirects breaking the journey. The system will be tested بالكامل in sandbox mode before switching to production keys, with full validation of success, failure, and refund scenarios. Thanks

Hello, I can integrate your Chinese payment gateway into your existing PHP website with a clean, secure, and modular implementation. I have solid experience with PHP, REST API integrations, payment gateways (including Alipay/WeChat-style flows), signature generation, and callback handling, so I can quickly connect your system end-to-end. I will implement token creation, order submission, signature logic, callback/notification handling, and refunds as per the gateway’s spec, and connect it to your checkout flow so users can complete payments seamlessly. I’ll also verify the full flow in sandbox, then switch to production keys once everything is confirmed working. The code will be structured in a modular way so you can plug in additional gateways later with minimal changes. You’ll receive clean, well-documented code along with a short README explaining configuration, keys, and signature handling so you can maintain it بسهولة. I can start immediately and complete this within 1–3 days depending on API complexity. Best regards, Asim Raza
