Here you will enter your Google Analytics Tracking ID "UA-xxxxxxxx". Then enable your integration and "Save Google Analytics Integration".
After you activate this integration within Visual Visitor, you will want to create/add "Goals" within Google Analytics. This will allow Visual Visitor to report your call data to Google Analytics.
