Application Programming Interface (API)

An application programming interface (API) is a set of definitions of the ways one piece of computer software communicates with another. It is a method of achieving abstraction, usually (but not necessarily) between lower-level and higher-level software. APIs are implemented by writing function calls in the program, which provide the linkage to the required subroutine for execution. Thus, an API implies that some program module is available in the computer to perform the operation or that it must be linked into the existing program to perform the tasks.

The Contribution API was introduced with ActiveVOS 8.0. Please note that this API has been folded into the ActiveVOS 9 Administration API.
