API

An API (Application Programming Interface) is a set of rules and protocols that allows different software applications to communicate with each other. It defines the methods and data formats that applications can use to request and exchange information, enabling integration and functionality sharing between systems.

Also known as: Application Programming Interface, Web API, REST API, API Endpoint, Application Interface

Why learn API?

Developers should learn APIs to build interoperable software, integrate third-party services (like payment gateways or social media), and create microservices architectures. They are essential for web development, mobile apps, and cloud-based systems where data exchange between components is required.
