Using the Visitor Tracking API

Businesses that want to pull website visitor tracking results into their own software or backend processes can use Lead Liaison's visitor tracking API web services. In the example below, we use the Get Visits (retrieves visitors) and Get Hits (retrieves web pages) API web services to retrieve visitor data. The sample code below is written in Java.
