The activeCollab API Wrapper is a set of PHP classes that makes using the activeCollab API much easier, by providing an object oriented interface. Instead of making HTTP requests from your code and handling responses, the wrapper layer lets you call a simple set of methods and work with the results in a form of PHP native types, such as arrays, objects, boolean values etc.
