What Does an API-First Approach Mean?

API-first means that you treat APIs as critical business assets, understanding the value they bring to your organization. You design each of your APIs around a contract written in an API description language like OpenAPI for consistency, reusability, and broad interoperability. Starting with an API contract allows you to better plan the design of your API and get feedback from stakeholders before writing any code.

Many APIs in use today have been around for more than two decades, but only in recent years have companies begun exploring and adopting the concept of API-first.
