Open API

An open API (Application Programming Interface) is like a set of rules that allow two different computer programs to "talk" to each other. With an open API, one program can ask the other program to do something and receive instructions back on how to do it. For example, if you want to use a photo editing program, you can ask the photo editing program to make the colors brighter with an open API. The photo editing program would then send instructions back to you on how to do it. In this way, an open API helps different programs to work together.
