API Banking

Leveraging API architecture to drive digital transformation

Open Banking and PSD2 are driving a new wave of innovation. To comply with each piece of legislation, banks must allow trusted third parties access to customer account data and the ability to initiate payments. Application programming interfaces (APIs) are the most effective mechanism for achieving this, allowing third-party providers access to banks’ data infrastructures in a way that is both open and secure.

However, banks should not consider these APIs as something needed only to meet regulations, but rather as a route to enhancing service offerings, improving overall customer engagement, and increasing revenue from new channels. An API architecture can help unlock hidden business value buried in legacy platforms and systems, and as a result, is a vital component in all digital transformations.


While many banks have taken initial steps with API implementation and have seen positive returns in terms of technology development, customer engagement, and business expansion, the majority still have work to do. Most are in the development phase, and few fully understand how an API-driven business model will work for them.
