API-Led Growth – The Need for an API-First Design and Documentation

APIs or Application Programming Interfaces form a fundamental technological pillar in our modern digital society. With the multi-application digital infrastructure of the current industry, an API-first design has become prudent for developers to allow their appliances to seamlessly communicate and exchange data with each other. As enterprises continue to depend on a growing suite of business applications to manage the various aspects of their operations, developers need to develop and maintain a library of APIs to streamline the integration of these multiple applications. However, to?ensure the quality and credibility of these APIs , proper API documentation is also a necessity.

What is an API-First Design

Before we delve into what is an API-first design, let us first break down the concept of APIs. API stands for Application Programming Interface, which allows different applications to communicate information. Now an API-first design philosophy is a product-centric approach by developers where the APIs take priority. Traditionally, software development prioritized code-first development in which developers focus on building the service first along with all its resources, with APIs being an afterthought. An API-first approach views the role of APIs as discrete products, rather than a last-moment addition subsumed into the applications. The main objective of an API-first approach to application development is to produce a holistic view of APIs as modular building blocks to drive application innovation with a focus on reusability.

Why Developers Must Have an API-First Design

With the growing number of applications in the market that offer greater and more specialized functionalities to businesses to manage their different workflow pipelines, the need for faster and more effortless integration between them has also become more prudent.?

Development Flexibility

With an API-first design, each API is treated as an individual product that offers the ability to work in parallel and achieve accelerated development.

Improved Developer Experience

As stated in the previous point, APIs are treated more like a product than a piece of software. With an API-first structure, the objective is to create a robust digital environment where developers can effortlessly access code, data, and templates to create applications on top of them.

Reduce Development Costs

While developing an API from scratch can be a costly process, the high reusability of the API helps brings down development costs in the long term.?

Faster Time to Market

The reusability of APIs offered by an API-first design philosophy also reduces the overall time of software development.?

How to Implement an API-First Design

For organizations still depending on traditional application development workflows, shifting to an API-first system can be a new experience but not necessarily a challenging transition.?

Layout Proper Planning

The first step to becoming an API-first organization is to have a structured plan with a draft overviewing the core objectives of the API operation along with a recording of all the details regarding how the core objectives are currently being done and the aspects that require improvement.

Ensure the Discoverability of APIs

For becoming API-first, organizations must invest in having a complete inventory of all the coding artifacts used across APIs being designed, developed, and operated in production while working on creating new artifacts for APIs.
