What Is an API | Domain Clout

An application programming interface (API) is a connection between computers or between computer programs, offering a service to other pieces of software, and is a type of software interface that enables different systems to communicate with each other, as seen in the development of [[web-development|web development]] frameworks like [[react-js|React JS]] and [[angular-js|Angular JS]]. APIs are designed to be used by computer programmers, who incorporate them into software, and are made up of different parts that act as tools or services, such as the [[rest-api|REST API]] protocol. The use of APIs has become increasingly important in the development of [[mobile-apps|mobile apps]] and [[cloud-computing|cloud computing]] services, with companies like [[amazon-web-services|Amazon Web Services]] and [[google-cloud-platform|Google Cloud Platform]] providing a wide range of APIs for various applications. As the [[internet-of-things|Internet of Things]] (IoT) continues to grow, the role of APIs in enabling device communication and data exchange will become even more critical, with [[mqtt|MQTT]] and [[coap|CoAP]] being two popular IoT protocols.
