Application programming interfaces are a way for computer applications to communicate even if they don't share a common programming language and exist in completely different parts of the world, or only live in the cloud.

An API is like a translator, or intermediary, that carries messages between the two programs that are formatted according to a set of predictable rules that allow for the exchange and manipulation of data. APIs operate as a layer of abstraction for developers to make it easy for them to use lots of different applications without learning how those applications were built or how they operate.
