APIs are sets of protocols, tools, and definitions that allow different software applications to communicate with each other. They define the methods and data formats that applications can use to request and exchange information, enabling seamless integration and interaction between systems, services, and platforms.
An API (Application Programming Interfaces) acts as an intermediary that allows two applications to talk to each other. It specifies how software components should interact, making it easier for developers to integrate functionalities from other systems without needing to understand their internal workings. APIs are used in web development, mobile apps, cloud services, and more.
