How Tin Soldier Helped Paymark Deliver a Modern Payment Experience
As digital commerce continues to evolve, consumers expect payment experiences that are secure, seamless, and trusted. For payment providers, delivering these capabilities across major eCommerce platforms is critical to supporting merchant growth and improving customer experiences.
That's why Tin Soldier partnered with Paymark to develop a custom Adobe Commerce payment module that enables merchants to offer Online EFTPOS payments through a secure hosted payment experience.
Who is Paymark?
Paymark is one of New Zealand's most recognised payment technology providers, enabling secure electronic payment transactions across the country's retail and commerce ecosystem. Through continuous innovation, Paymark helps businesses connect with customers through trusted payment solutions that make transacting easier both in-store and online.
As online commerce continues to grow, Paymark identified an opportunity to make its Online EFTPOS capability more accessible to merchants operating on Adobe Commerce (formerly Magento), one of the world's leading enterprise eCommerce platforms.
The Challenge
Paymark required a payment module that would allow Adobe Commerce merchants to integrate Online EFTPOS directly into their checkout experience without introducing unnecessary complexity or increasing PCI compliance obligations.
The solution needed to:
- Integrate seamlessly with Paymark's online payment platform.
- Provide a secure hosted payment experience for customers.
- Support real-time payment confirmation.
- Enable merchants to process full and partial refunds directly from Adobe Commerce.
- Maintain compatibility across Adobe Commerce Open Source and Commerce editions.
- Support modern frontend frameworks including Hyvä Themes and Hyvä Checkout.
- Deliver a scalable and maintainable architecture for future growth.
What Tin Soldier Delivered
Tin Soldier designed and developed an Adobe Commerce payment integration that connects merchants directly to Paymark's hosted Online EFTPOS platform.
Key features of the solution included:
Secure Hosted Payment Experience
Customers are redirected to a securely hosted Paymark payment page to complete their EFTPOS transaction. This approach ensures sensitive payment information never passes through the merchant's Adobe Commerce environment, significantly reducing PCI compliance requirements.
Real-Time Payment Processing
The module combines webhook notifications and API polling to ensure payment statuses are updated accurately and reliably within Adobe Commerce.
This allows merchants to maintain confidence that orders are processed correctly while delivering a smooth customer experience.
Native Adobe Commerce Refunds
Merchants can perform full or partial refunds directly through Adobe Commerce using standard credit memo functionality, eliminating manual processes and reducing operational overhead.
Comprehensive Transaction Visibility
Administrators gain visibility into key transaction information directly from the order screen, including:
- Merchant Transaction
- IDs Payment IDs
- Payment status updates
This improves support efficiency and simplifies payment reconciliation.
Future-Proof Platform Compatibility
The module was designed to support:
- Adobe Commerce 2.4.6, 2.4.7, 2.4.8
- PHP 8.1 through 8.4
- MySQL and MariaDB environments
- Hyvä Themes and Hyvä Checkout
This ensures merchants can adopt the solution confidently across a wide range of environments.
The Outcome
The project delivered a production-ready Adobe Commerce payment module that enables Paymark's Online EFTPOS offering to be deployed quickly and consistently across merchant websites.
The key business outcomes included:
- Expanded access to Paymark's Online EFTPOS service within the Adobe Commerce ecosystem.
- A secure hosted-payment architecture that minimises PCI compliance complexity for merchants.
- Improved customer trust through a familiar EFTPOS payment experience.
- Reduced operational effort through automated payment reconciliation and native refund management.
- A scalable integration framework that supports future platform enhancements and merchant adoption.
Why It Matters
Online shoppers increasingly expect payment options that align with how they bank and transact in everyday life.
