How SurePay future-proofed its API platform with Apigee X

As API traffic continued to grow and regulatory requirements became increasingly demanding, SurePay needed a platform capable of delivering the performance, availability and security that real-time financial services require. Together with AppyThings, SurePay migrated from Apigee Edge to Apigee X through a fully automated, zero-downtime migration.

SurePay helps financial institutions and organizations verify payment details before transactions take place.

Its services play a critical role in reducing payment errors, fraud and operational risk. Every verification request depends on APIs that need to be available, secure and responsive at all times.

For an organization operating at this scale, API performance is directly linked to customer experience, business continuity and regulatory compliance.

The challenge: scaling a mission-critical API platform

SurePay's API platform processes millions of verification checks every month.

As the business continued to grow, maintaining consistent performance and high availability became increasingly important. At the same time, compliance requirements such as PSD2, Confirmation of Payee (CoP) and ISO 27001 placed additional demands on the platform.

The existing Apigee Edge environment had served the organization well, but it was becoming clear that a more modern API management platform was needed to support future growth.

SurePay needed a platform that could:

• Scale seamlessly with growing API traffic
• Maintain high availability and business continuity
• Provide deeper operational insight
• Strengthen security and compliance capabilities
• Reduce operational complexity
• Support future innovation

Most importantly, the migration needed to happen without disrupting the services that customers rely on every day.

The solution: a zero-downtime migration to Apigee X

AppyThings partnered with SurePay to migrate the platform from Apigee Edge to Apigee X. The migration was designed around three key principles: scalability, security and continuity.

Using a Terraform-driven approach, AppyThings automated provisioning and configuration to create a consistent and scalable platform foundation. At the same time, the architecture was enhanced with advanced observability capabilities and AI-powered security features.

The project included:

• Migration from Apigee Edge to Apigee X
• Automated provisioning and configuration using Terraform
• Scalable cloud-native architecture design
• Enhanced observability and monitoring capabilities
• AI-driven security controls
• Compliance-focused platform implementation
• End-to-end migration support and validation

Through careful planning and execution, the migration was completed without service interruption, ensuring business continuity throughout the transition.

Delivering performance, visibility and security at scale

A migration of this nature is about more than replacing infrastructure. For SurePay, the objective was to create a platform capable of supporting the next phase of growth while maintaining the trust and reliability expected in financial services.

The new Apigee X platform provides greater visibility into API traffic and performance, allowing teams to monitor usage patterns, identify issues faster and make better operational decisions.

At the same time, enhanced security controls and compliance capabilities help ensure the platform continues to meet the standards required in a highly regulated environment.

The result: a future-ready API platform

The migration delivered a modern API management foundation built for scale, resilience and continuous innovation.

Key outcomes included:

• A platform built for massive scale: SurePay now operates an Apigee X environment capable of handling more than 8 billion API calls while maintaining performance and reliability.
• Advanced observability: Real-time monitoring, analytics and tenant-level insights provide deeper visibility into API traffic, platform performance and operational health.
• Stronger security and compliance: The platform supports compliance requirements such as PSD2, CoP and ISO 27001, while AI-driven security capabilities strengthen protection across the API ecosystem.
• High availability and business continuity: With 24/7 availability and disaster recovery capabilities, the platform is designed to support uninterrupted service delivery.
• Reduced operational overhead: Automation and modern cloud-native architecture help simplify platform management and reduce operational complexity.
• Faster API performance: Improved response times contribute to a better experience for customers and partners while supporting continued business growth.
• A partnership built on expertise and trust: For SurePay, selecting the right migration partner was just as important as selecting the right platform.

As Friso Schutte, CTO at SurePay, explains:

"APIs are at the very core of our business, and migrating to Apigee X was a critical step in futureproofing our platform. With millions of API calls every day, we cannot afford missteps.

AppyThings proved to be an outstanding partner in this journey. Their deep technical expertise, strategic guidance, and hands-on support ensured a seamless migration without disrupting our operations."

Why this matters

Organizations often postpone API platform modernization because the risks of migration appear too high.

But when API traffic continues to grow and compliance requirements become more demanding, legacy platforms can become a constraint rather than an enabler.

The SurePay migration demonstrates that modernization does not need to come at the cost of business continuity.

With the right strategy, automation and expertise, organizations can modernize mission-critical API platforms while maintaining availability, improving security and preparing for future growth.
