API specification

API specification refers to a detailed document that outlines how different software applications can communicate with each other through an Application Programming Interface (API). It defines the methods, data formats, and protocols that developers use to request and exchange information. Think of it as a user manual for software interactions, detailing what actions can be performed, what data is required, and what responses to expect. This ensures that different systems can work together smoothly, enabling seamless integration and functionality, much like a common language that allows various software components to collaborate effectively.
