In addition to configuring Geofence rules in Pega Customer Decision Hub , the app that wishes to detect when a Geofence is entered (tripped) must make service requests to the system to determine if a Geofence is tripped. If a Geofence is tripped, all Events associated with it will be triggered (assuming they are currently applicable). The system provides multiple services which can be used separately or in tandem to facilitate this functionality.
