APIs

CAMPD uses web services to display data via an Application Programming Interface (API). An API is a set of commands, functions, protocols, and objects that programmers can use to create software or interact with an external system. An API interprets that data and presents you with the information you wanted in a readable way. These services and associated documentation provide an additional means of accessing CAMPD’s data.
