Overview

Integrating HBL’s outdated payment gateway with 2C2P v2 in a modern JavaScript stack felt like a nightmare. The system’s ancient PHP roots, useless documentation, and non-existent support turned what should have been a few days’ work into 3 weeks of untangling chaos.

The Pain Points

Stuck on 2C2P v2: The PHP version was old, undocumented, and confusing.

No support: Any official guidance was basically non-existent.

Reverse engineering required: After wasting 2 weeks, I had to reverse-engineer their v2 payment flows in PHP just to understand what was happening.

The Solution

I rebuilt the entire integration in Next.js, with:

• Secure JOSE encryption
• Clean, maintainable payment flows
• Modern architecture compatible with current JS standards

Finally, the payment flow works reliably, is maintainable, and no longer relies on obscure legacy PHP logic.
