This guide delves into the API lifecycle, outlining the critical stages that define an API's journey, from its initial conception and design to deployment, active use, and eventual deprecation. By understanding these distinct phases, organizations can effectively create robust, secure APIs that empower both internal and external stakeholders, ultimately driving innovation and fostering a thriving digital ecosystem.

What is an API?

An API, or Application Programming Interface, is a messenger between different software applications. It defines a set of rules and protocols that allow them to communicate and exchange data.

You can think of an API like a waiter in a restaurant: the API takes requests from one application (the customer), relays them to another application (the kitchen), and delivers the response back. This enables seamless interaction and data sharing, forming the backbone of many modern software functionalities.
