Getting Started with API-First Design

API-first design means treating your API as a core product: well-documented, versioned, and easy for both your own frontends and third-party integrations to consume. The result is more flexible systems and faster feature delivery.

This post introduces the basics: REST and consistency, OpenAPI specs, versioning strategies, and how to test and document your API. Whether you’re building a mobile app, a SaaS, or internal tools, an API-first approach pays off.
