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 />
