callbacks - Items API


The Callbacks object contains optional callback functions that allow detection of the ready status of an Items API instance and any errors encountered.

The readyListener callback in particular is very important for the correct functioning of Items API. Most of the methods provided by the returned object from window.LearnosityItems.init() will not be fully available until after the readyListener callback has triggered.
