Case Study: Global Bank achieves faster API innovation with OpenLegacy

Global bank uses OpenLegacy to launch a Global API, the foundation for customer experience innovation - within days

Global Bank, a large international financial institution serving hundreds of millions of customers, needed to accelerate digital innovation and scale API integration across its core systems. Its challenge was to build a global API connecting legacy platforms like Mainframe and AS/400 while keeping pace with growing demand for new customer experiences and services.

Global Bank turned to OpenLegacy to rapidly create APIs and microservices, starting with SME credit application workflows and related transactions. OpenLegacy delivered five APIs in just three days, helping reduce a growing backlog, cut time to market, and lower development costs; the case study says OpenLegacy was 8x less costly than the bank’s previous approach and also simplified deployment and reduced risk.
