The Technical Hurdle: Meeting Complex Payment Requirements

When Galco approached SwiftOtter, they had a very specific need: integrate the Worldpay payment gateway into their site in a way that met strict security and compliance requirements—without disrupting user experience. Worldpay was a non-negotiable provider, but their available integrations didn’t suit the Galco team’s expectations or frontend requirements. The challenge wasn’t about volume, it was about specificity. And getting it right.

The integration needed was not available out-of-the-box, and the complexity of their tech stack meant the solution had to work seamlessly without disrupting checkout flows, inventory logic, or business operations. SwiftOtter was brought in to deliver a custom solution and ensure the payment system could be implemented successfully. We worked in collaboration with Blue Stingray, Galco’s existing agency, throughout the process.

Uncovering the Real Challenge: A Standard Integration That Was Anything But

At first glance, the Worldpay implementation seemed like a relatively standard ask. But as we dug in, we uncovered deeper complexities with how the integration would interact with Galco’s existing architecture and checkout flow. Mid-project, it became clear that the originally scoped solution wouldn’t meet the business’s real needs.

Worldpay’s Magento compatibility was limited—and none of the pre-built options met Galco’s expectations for styling, functionality, or maintainability.

Multiple teams were involved. SwiftOtter handled the integration, but Galco’s core development work was being led by another agency, Blue Stingray—adding layers of complexity to communication, expectations, and handoffs.

Early assumptions proved incorrect. What initially seemed like a plug-and-play integration quickly became a custom implementation effort with legal, technical, and UX implications.

As the true scope of the project came into view, we shifted our approach. Rather than retrofitting an existing module, SwiftOtter proposed a custom iframe implementation of the Worldpay payment fields—giving Galco full control over styling while maintaining PCI compliance.

To ensure steady progress and alignment, we:

• Held daily stakeholder calls between Galco, SwiftOtter, and Blue Stingray—ensuring decisions were made quickly and blockers removed in real time.
• Looped developers directly into calls, reducing translation errors and improving accountability on all sides.
• Scoped the solution tightly, treating all out-of-scope requests as formal change discussions to avoid scope drift and maintain clarity.

What was supposed to be a simple module install evolved into a strategic engineering effort. SwiftOtter needed to deliver a solution that was compliant, stable, and branded—without disrupting the broader Magento ecosystem or Galco’s critical business processes.

This hands-on, transparent rhythm helped the cross-agency team stay focused—despite bumps in the road—and gave Galco peace of mind that their integration was being handled with care.

Results & Outcomes: A Trusted System, Built for Longevity

By the end of the engagement, Galco had a fully functional, custom-integrated Worldpay solution that met their UX requirements and supported their business continuity needs.

Wins included:

• A smooth, styled checkout experience that aligned with brand expectations
• A PCI-compliant payment solution tailored to their infrastructure
• Stronger cross-agency communication and trust
• A reusable approach that could serve future payment customization efforts

Despite the project’s complexity, SwiftOtter delivered what mattered most: a working solution that supported Galco’s business, and a process that rebuilt momentum and confidence at a critical point in their eCommerce roadmap.
