Application programming interface

From Simple English Wikipedia, the free encyclopedia
(Redirected from API)

An application programming interface (API) is a set of functions, procedures, methods or classes used by computer programs to request services from the operating system, software libraries or any other service providers running on the computer. A computer programmer uses the API to make application programs.

An API works [1] by communicating with and exchanging data with other systems, acting as a messenger between the user and the system to retrieve the necessary data the user is requesting from the system.

Main types of web APIs:[2]

  • Open APIs - available to the public; they can be accessed by any external users.
  • Partner APIs - available to strategic business partners; they are exposed to a public API developer portal.
  • Internal APIs - available to a company's internal development teams; they are exposed to a private API developer portal.
  • Composite APIs - are a sequence of tasks bundled into a single API call.

Types of API include web services API like the Twitter API, which allows programs to use the API to receive updates on tweets.
