What is API?

An application program interface (API) is a set of definitions, routines, protocols, and tools for building and integrating software applications. APIs are the software intermediary that allows applications to talk to one another and work together. The API specifies how software components should interact, letting your product or service communicate with other products and services without having to know the specifics of how they’re implemented. APIs cut significant time out of the application development process.

APIs are also used when programming graphical user interface (GUI) components. A good API makes it easier to develop a program by providing all the building blocks, so that the programmer only needs to put the blocks together.

Each time you use an app like Facebook, send an instant message, or check the weather on your phone, you’re using an API – one that goes from your mobile phone to the Internet to a server, and then back to your phone. All of this happens via API.
