From operational efficiency to digital disruption
Application programming interfaces (APIs) have been around for decades. In the early days of IT they were primarily
used to give programmers convenient access to libraries of prebuilt functions. As systems became more distributed, APIs
found their place in more general application and data integration. They allowed remote capabilities and resources to be
accessed easily across a network. By separating interfaces from implementation, they also encouraged a more flexible
and robust component-based approach to software development. Fast forward to today’s highly connected world of web
services, mobile apps, the Internet of Things and open data, and the smart use of APIs, built and managed using up-todate
techniques, has become a critical enabler of digital transformation.
