Sitecore 9 - Incrementing engagement value

Question

The following code worked on Sitecore 8.x to increase Engagement Value programmatically:

Tracker.Current.Interaction.Value += value;

This code compiles and executes file on Sitecore 9.0.1, but after flushing my session and looking up the interaction in the xDB Interactions table, the EngagementValue column still has a value of 0. Is there an additional step needed with the Tracker on Sitecore 9?

Answer 1

In Sitecore 9.x, the engagement value is a calculated facet.

If you want to increase the engagement value, you should add an event where you are setting the engagement value e.g.

using (XConnectClient client = SitecoreXConnectClientConfiguration.GetClient())
{
  try
  {
    var reference = new IdentifiedContactReference(source, identifier);
    var contact = client.Get(reference, new ExpandOptions());

    int engagementValue = 10;

    var interaction = new XConnect.Interaction(contact, InteractionInitiator.Brand, channelId, userAgent);
    var engagementValueEvent = new Event(Guid.NewGuid(), DateTime.UtcNow)
    {
      EngagementValue = engagementValue
    };
    interaction.Events.Add(engagementValueEvent);

    client.AddInteraction(interaction);

    client.Submit();
  }
  catch (Exception e)
  {
    //
  }
}
