API Server

An API server is a software component that handles requests and responses for an Application Programming Interface (API), typically over HTTP/HTTPS. It processes client requests, executes business logic, interacts with databases or other services, and returns structured data (often in JSON or XML format) to clients such as web or mobile applications.

Also known as: API Backend, REST Server, Web API Server, API Gateway (in some contexts), HTTP API Server
🧊Why learn API Server?

Developers should learn about API servers to build scalable and interoperable backend systems that enable communication between different software components. This is essential for creating web applications, mobile apps, microservices architectures, and integrating third-party services, as it standardizes data exchange and decouples frontend from backend logic.
