Challenge
An established EU pharmaceutical company needed to accelerate a shift to an “API First” approach across a complex landscape of external partners and government/country interfaces. Their existing integration model leaned heavily on legacy, batch-style processing and an API/ETL approach that wasn’t designed for real-time exchange or rapid onboarding of new participants.
As volumes and dependencies increased, the platform became a constraint: it was difficult to evolve, operationally heavy, and not positioned to scale to the levels the business was forecasting. The client needed a modern integration foundation that could support a growing ecosystem, stronger governance, and a clear path from millions of interactions into the tens—and eventually hundreds—of millions.
Solutions
We modernized the client’s existing API/ETL capability and delivered a new integration platform centered on WSO2 API Manager and WSO2 Micro Integrator. The work went beyond a technical refresh: we re-shaped the way integrations were implemented and delivered so the platform could be used consistently across many partners and countries, rather than relying on one-off builds.
In parallel, we established a structured approach for implementing and releasing API integrations at scale, so onboarding new APIs and consumers became repeatable and controlled. The result was a platform that supports high-volume API traffic, predictable operations, and a delivery model that can keep pace as the partner ecosystem expands.
Technologies
The solution was built primarily on WSO2 API Manager and WSO2 Micro Integrator, using Python and Java for implementation where needed. We enabled delivery and release practices through Azure DevOps and operated the platform on Linux CentOS servers.
To support performance and integration patterns, Redis and AMQ were used where appropriate within the overall solution. Together, this technology stack provided a strong balance of enterprise API management, scalable integration runtime, and the operational tooling required for sustained growth.
Innovations
A key innovation was making data available to partners in real time through APIs, replacing the historical dependence on overnight EDI processing. This shift improved responsiveness across the ecosystem and enabled partners and country organizations to interact with the client’s services and data when it was needed, not after a batch window.
We also introduced API development standards and cybersecurity controls designed to actively protect the client’s networks while enabling broad external consumption. This ensured that scaling the platform and onboarding more consumers did not come at the expense of governance, consistency, or security.
Team Structure
The delivery team consisted of eight API developers supported by two technical leads, forming a stable product-style capability for platform delivery and partner integration rollout. This structure enabled parallel delivery across multiple integrations while maintaining architectural consistency and quality controls.
The technical leads ensured that standards, platform patterns, and operational requirements were applied consistently, while the developers focused on implementing integrations efficiently within the established framework. This balance helped keep delivery scalable without sacrificing maintainability.
Results
We scaled the platform from ~2 million interactions to more than 50 million, improving both throughput and operational reliability as adoption increased. The modernized platform and delivery approach enabled the client to expand partner integrations faster while maintaining consistent standards and governance.
The solution is designed to support continued growth, with interaction volumes expected to reach over 500 million within the next two years. Most importantly, the client now has an integration platform that supports real-time exchange and a repeatable model for delivering APIs and integrations at enterprise scale.
