API (Application Programming Interface)

An API (Application Programming Interface) is a set of rules and protocols that allows different software applications to communicate with each other. APIs enable developers to access specific features or data of an application, service, or platform without revealing the underlying code. Commonly used in web and mobile development, APIs enhance functionality and streamline integration between systems.

For example, payment gateways, social media logins, and weather updates often rely on APIs. By enabling seamless data exchange, APIs play a vital role in modern software development, improving efficiency, scalability, and user experience across various platforms and devices.
