ABSTRACT<br />
Banks must think beyond<br />
regulatory minimums<br />
when considering<br />
Open Banking APIs.<br />
Read more about how<br />
forward-looking banks are<br />
unlocking business value<br />
with APIs for application<br />
integration, banking as a<br />
platform, innovation, and<br />
client connectivity.<br />
With regulatory initiatives well underway in<br />
the Euro Zone and the UK, it is clear that<br />
open banking APIs are inevitable. APIs are<br />
critical technology enablers for several<br />
use cases in banking including application<br />
integration, banking as a platform,<br />
innovation, and client connectivity.<br />
Web services, microservices, and APIs enable<br />
legacy modernization by wrapping legacy<br />
systems with a decoupled integration layer,<br />
bridging traditional batch-based processes<br />
to real-time, digital cloud, mobile, and<br />
social applications. APIs enable the modular<br />
application stack underlying Banking as a<br />
Platform and provide neobanks with stateof-the-art<br />
digital banking capabilities. As<br />
open banking grows, driven by regulatory<br />
imperatives, shifting customer demands, and<br />
the threat of fintech firms, APIs connect banks<br />
and third party firms entering into collaborative<br />
partnerships for innovation. To access banking<br />
services, most customers manually log in<br />
to a web-based or mobile platform, pulling<br />
balance and transaction data on demand. APIs<br />
are emerging as a new connectivity channel,<br />
streamlining and securing on-demand,<br />
programmatic access to financial data for<br />
accounting packages, treasury management<br />
systems, and ERP platforms.<br />
We offer updated case studies from CBW<br />
Bank, Fidor Bank, JB Financial Group, Citi, and<br />
YES BANK detailing their API journey, including<br />
technology architecture, monetization<br />
approach, and latest results. For banks seeking<br />
to begin their API journey, we recommend a<br />
series of guideposts that they can follow to<br />
unlock business value with APIs. <strong>MBR</strong><br />
