The API economy is upon us. This is a new age where APIs are not just allowing business to build and scale faster, but are also driving strategic initiatives and achieving business targets. In such an ecosystem, your speed to market and consumer experience play a vital role in the success of your API programs. REST APIs have come to take center stage in the API economy primarily due to their scalability, reliability, and ability to decouple server and client.
The definition driven approach to API development helps in delivering quality, consumable APIs at faster velocities. The approach is based on designing the API interface first with an open standard, and using that to create better implementation logic, improve developer experience when using APIs, and enhancing overall quality of the delivered APIs.
