To fuel its growth, this large global payments processor for financial institutions used a merger and acquisition strategy. This approach allowed them to extend the value they provided to their clients but created significant challenges for their legacy IT infrastructure. Their back end systems became increasingly fragmented as multiple platforms and systems were integrated to support each of their major products. Multiple user interfaces and the complexities associated with a variety of business processes and standards introduced a lack of uniformity and consistency for their customers.

How API-Based Approach Helps Large Global
Processor Accommodate Growth

Mergers and Acquisition Strategy Creates Issues for Legacy IT
Dynamic Growth in Digital Marketplace Drives New Strategic Direction
This leading organization wanted to define an API-based strategy that would allow them to build a more dynamic and flexible environment. Several steps would be required to develop this strategy including defining the product development methodology, architecting the product lifecycle, selecting the right platform and implementing best of breed technologies. In addition, it would be necessary to ensure that the organization’s people, processes and controls were ready to support this new approach. Lastly, the silo-based architecture and legacy systems driving the back end processing for the firm would need to be configured to support the API strategy and the platform that would be selected to implement that strategy.

- Description of the infrastructure capabilities required to support the API product lifecycle management, discovery, and operational parameters and ongoing evolution of each of these.
- Identification of the necessary components required for creating a superior developer experience and user friendly portal and sandbox approach.
