AR Filter API plug-ins introduction
AR System Filter (AR Filter) API plug-ins enable you to create tight, efficient integrations between your systems and the AR System server . They are triggered with Set Field actions in filters and escalations. Because this middleware is loaded as a plug-in when AR System is started instead of as a standalone executable at each event, it consumes fewer resources and less processor time than a Set Fields $PROCESS$ action.
At run time, the AR System server sends AR Filter API requests to the plug-in, which directs the requests to the appropriate plug-in. The plug-in processes the input arguments and can return values that can be used in the Set Fields action.
When you enter AR Filter API requests in the Create Filter form, the AR System server sends the requests to the plug-in, which sends them to AR Filter. AR Filter processes the data or request itself, or it retrieves output data from the external data source and returns it in the opposite direction. To create AR Filter Set Field actions in filters and escalations, use Developer Studio .
Unlike AREA plug-ins, the plug-in server can simultaneously load multiple AR Filter API plug-ins.
The following figure shows the flow of requests and information for AR Filter API plug-ins.
