API

An application programming interface (API) is a set of specifications that allows software programs to interact. Web applications typically conform to a client-server architecture with an API to connect the "client" to the "server." In a nutshell,

• a client requests some data,
• that data travels to a web server application over the HyperText Transfer Protocol (HTTP),
• the web-server application takes the requests and processes the data,
• and the data is then sent to the client over HTTP.

In this chapter, we'll explore the concepts and terminology behind web APIs.
