What is an API?

API: The pipes that carry data between any number of

systems. Think of them as veins and arteries carrying blood from your heart to other organs.

API Provider: Who build, owns, and maintains the APIs

that are being used.

API Consumer: You! Any developer, company, or end

users accessing information via the API

A is for “Application”

• Web-based Systems

• Operating Systems

• DB Systems

• Computer Hardware

• Software Libraries
