An API (Application Programming Interface) is a set of rules and protocols that allows different software applications to communicate with each other. It defines how requests are made, what data is exchanged, and how responses are formatted, enabling different systems or components to interact seamlessly. APIs serve as a bridge between different software systems, allowing them to "talk" to one another without knowing how the other system is implemented internally.
For example, when you use a weather app on your phone, it may use an API to send a request to a weather service's server for the latest forecast data. The weather service then responds with the requested data, and the app displays it to you. APIs can be used for various purposes, such as retrieving data, integrating services (like payment gateways), or accessing specific functionalities of a system (like user authentication). APIs are essential in modern web development, enabling the integration of third-party services, data sharing, and enhancing the functionality of applications.
