Application programming interface (API)

An application programming interface (API) is a system of tools and resources in an operating system enabling developers to create software applications. An API is a software intermediary allowing two applications to talk to each other. Each time you use an app like Facebook, send an instant message, or check the weather on your phone, you are using an API. Frye, M-K. (n.d.). What is an API?
