Digital transformation is no longer a buzzword. It has become a way of life for enterprises that want to stay in business. In the current post-pandemic era, business maturity is being evaluated in terms of digital maturity. The road to digital adoption has many emerging technologies in force but working silently behind the scenes and aiding this rapid acceleration, is the unseen ‘super glue’ of all business services – Application Programming Interfaces (API). Technically, APIs have been around for two decades at different levels of operability but it is only in recent years that there has been an explosion of sorts in the usage of APIs.
The demand for multichannel experiences and the everything-on-cloud approach has accelerated the use of APIs. Whether it be composable architecture or microservices, APIs enable the kind of business collaborations that were unheard of before. The partnering of transportation services with a bank, retail shops with payment apps, and banks offering investment opportunities, loans, currency transactions, and payment services on an e-commerce platform have all been made possible by the growth of APIs. Similarly, offloading certain business tasks to ecosystem partners and liberating internal services from silos has been fueled by the synergy between APIs.
API-driven development is the practice of designing and building the API contract first and then developing the application around the contract. Also, known as the API-first approach, this paradigm involves the front-end developers building mocks around APIs and creating refined end-user experiences. In parallel, the back-end developers implement the underlying logic of the APIs.
Dedicated test suites are created around these APIs and, in a way, they foster the idea of test-driven development. In an API lifecycle, the API Publisher designs and deploys the API whereas the API Consumer discovers and integrates the APIs. Each of these roles has multiple functions associated with them and those functions define the characteristics of the API.
WaveMaker is an open standards-based, developer-centric low-code platform built for modern development practices. The platform enables app developers to play the role of an API Publisher and API consumer. The platform has a natively integrated component called the API Designer which is used to ease the process of designing, creating, and consuming APIs.
