Built from the ground up on modern API foundations
We developed a complete payment integration for ICEPAY, built entirely from the ground up on their modern checkout API. This project gave us the opportunity to create a fresh, contemporary Magento 2 integration using modern development practices, along with dedicated Hyvä Checkout compatibility from day one.
ICEPAY's existing Magento integration had become heavily outdated, built on their legacy API and no longer following modern Magento development standards. With ICEPAY launching a new checkout API, they needed a complete rebuild that would leverage contemporary practices and provide immediate support for the growing Hyvä ecosystem.
Rather than updating the legacy codebase, we built a brand new integration from scratch on ICEPAY modern checkout API. This greenfield approach allowed us to implement current Magento best practices, ensure Hyvä Checkout compatibility from the start, and establish comprehensive end-to-end testing to guarantee reliability.
The integration supports a focused selection of popular European payment methods:
Credit Card: Standard credit and debit card payments
iDEAL: Leading Dutch online payment method
Bancontact: Preferred Belgian payment method
PayPal: International digital wallet
Sofort: Direct bank transfer method for German markets
Online Überweisen: German online bank transfer
EPS: Austrian e-payment standard

The integration was built from the ground up using ICEPAY's modern checkout API, allowing us to implement contemporary Magento development practices without being constrained by legacy code. We focused on creating a clean, maintainable codebase that follows current standards for dependency injection, service contracts, and API design. The redirect-based payment flow integrates smoothly with both standard Magento and Hyvä checkouts, providing a consistent experience across both platforms. Comprehensive end-to-end tests validate all payment flows, ensuring reliability and catching issues before they reach production.

The integration provides ICEPAY with a rock-solid, modern payment solution for both Magento 2 and Hyvä Checkout stores. By building from scratch on their new API, we delivered a clean, maintainable codebase that follows contemporary development practices and will serve as a reliable foundation for years to come. The comprehensive end-to-end testing ensures merchants can trust the integration to work correctly across all supported payment methods, providing the reliability and performance modern e-commerce demands.
