Identify returning user interaction data from xDB in Sitecore 9

Question

I have a requirement to identify the returning user which haven't yet created their profile. I know that Sitecore gives the unique identifier to the anonymous user based on the device and stores the information in the cookie.

But when I am trying to get the interactions data from the xConnect API using below code:

var session = Sitecore.Analytics.Tracker.Current.Session.Interaction

I am only getting the pages from the current visit of the user. Even though I am using the same device and same browser.

How do I get all the previous sessions that visitor has browsed assuming they haven't cleared their browser cookies.

Answer 1

You can use ContactRepository to load previous interactions:

ContactRepository contactRepository = Factory.CreateObject("tracking/contactRepository", true) as ContactRepository;//or new ContactRepository();
IEnumerable<IInteractionData> lastInteraction = contactRepository.LoadHistoricalInteractions(contactid, visitsToLoad, pastDateTime, currentDateTime);

Where:

• visitsToLoad - amount of visits that you are interested in.(Could be int.MaxValue)
• pastDateTime - from what date filter, could be null
• currentDateTime - to what date filter, could be null
