Well-known for their distinctive in-store experience, our client, an international retail giant, needed to scale their digital ecosystem to support ongoing expansion into new markets. To modernize legacy backend systems and future-proof their online customer experience, the retailer looked to Fusion Alliance for help. 

Our team designed a composability framework that took the client from an API first commitment to flexible API modernization — with dramatic results.

Our client’s new CEO wanted to replicate the brand’s in-person experience with a digital presence that could easily evolve and scale to fit current and emerging markets. With an eye toward a new push into Asia, the company needed a solution that could easily and quickly reach – and resonate with – millions of new customers. 

The client understood that replicating a flourishing in-person shopping experience online would require a significant digital transformation. They were ready to tackle the technology challenges and were committed to an API first mindset going forward, but with so many modernization options available, they weren’t sure where to start. 

They enlisted Fusion Alliance to design and implement new technology architecture, with the end goal of an improved global presence. 



To meet the client’s goal, Fusion stepped in to design and implement a flexible, scalable, modern technology ecosystem.  

Like most organizations, our client’s existing technology portfolio contained a patchwork of idiosyncratic systems and aging legacy platforms. But simply replacing the hodge-podge with another monolith wouldn’t deliver the kind of connectivity, resilience, and global extensibility that the client’s vision demanded.  

Instead, our team recommended an API first strategy to bridge the gap between existing applications and a future-focused, rich integration architecture. 


Phase 1: An API First Strategy

Because the client’s outsourced API functionality limited their flexibility, we recommended an API modernization strategy to bring the integration back in-house. This approach allowed for flexibility in new development, as well as the ability to re-design and re-architect as needed. 

To translate “API first” into action, we collaborated with the client’s internal teams to design a roadmap that aligned internal business objectives with concrete steps toward digital transformation.  

The roadmap covered three key areas of focus: 

  • Designing the reference architecture: To drive toward a modern, scalable architecture, our team researched, socialized, and agreed on a go-forward combination of essential capabilities, platforms, and components. 
  • Establishing key business capabilities: While many of the client’s existing processes and platforms were adequate for the current state, we identified key business capabilities needing additional support for channel modernization. 
  • Platforms and tools analysis: Equipped with the desired reference architectures, the team explored a variety of software packages across IPaaS, marketplace, API management, and other COTS/SaaS to accelerate the future program effort. 

The resulting blueprint surfaced possibilities and equipped the client to make clear decisions around their API modernization immediately, while positioning the brand to grow over the long-term.  

Phase 2: Pilots & Acceleration

Equipped with the blueprints to drive the integration modernization program, our team laid out the key infrastructure needed to drive API first success. 

  • We selected and deployed an API marketplace, the heart of the future integration topology, and began exposing mission-critical APIs in that direction.  
  • The team layered in other modern platforms, including Confluent Kakfa, to accelerate the modernization plan.  
  • We produced, exercised, and shared the key accelerators and templates needed to enable future federated delivery models across all business units. 
  • Integral to the overall program, we established a center for API enablement across all technology and platform teams.  
  • We created an API marketplace document repository and hosted API first training sessions.

Ultimately, implementing API modernization is an organizational change project. Our work not only laid the technical groundwork and built out a modern API ecosystem, but also gave the client the knowledge and confidence to be successful from day one — and well into the future. 


Today, the client’s online presence reflects the elevated in-store shopping experience that made their brand a household name. As customer expectations shift and new opportunities emerge, they can easily adjust and respond with seamless improvements. 

  • The client can now access their new, modern technical infrastructure from anywhere in the world. 
  • Using their API marketplace, they can easily access integrations to deliver needed functionality, make edits and improvements, and keep up with shifts in traffic.
  • With the internal knowledge and skill to adjust, they are ready and equipped to respond quickly and effectively to change and opportunity.  
  • Their team plans for demand and implements new tools as needed, instead of just keeping up with current needs.  
  • They drive business agility and productivity by enabling innovation with data and integrations.  
  • Through self-service enablement, reporting is now more efficient and economical. 

Most importantly, API modernization equipped the client team to meet their overall business goal of expansion on a global scale. By putting API first ideas into practice, the client continues to see significant ROI, including:
