What Is an Application Programming Interface (API)?

  • An API is a method to open up and allow access to specific content or functionality from within an
    application. An API allows other developers or organizations the ability to use specific functionality,
    usually to build or produce new functionality. An API has specific rules and requirements that allow
    users to properly access the content or functionality.
