An API, or Application Programming Interface, is a set of rules and protocols that allow different software applications to communicate with each other. APIs are used in programming to define how software components should interact, making it easier for developers to integrate different services, functions, or data into their own applications. This helps developers save time and resources by leveraging existing code and functionalities rather than re-creating them from scratch. It also promotes modularity, reusability, and efficiency in software development.
