Creating a personalization rule based on user LastLogin date

Question

I have a requirement to create a personalization rule to change the rendering display based on whether the user is First Time user or New User.

The first-time user will be decided if the users last login or contact. InterAction is null.

The New User user will be decided if the users last login or contact. InterAction date is less than 30 days.

I want the Last Logged in date from the Sitecore contact. InterAction. How do I do GetContact and what do I need to pass as parameter. How do I get the contact. InterAction value. using xconnect.

Sitecore provides a flag to identify new anonymous users on the tracker: Tracker.Current.Contact.IsNew

You can use this in a condition as below:

public class IsFirstTimeUserCondition<T> : WhenCondition<T> where T : RuleContext
{
    protected override bool Execute(T ruleContext)
    {
        if (Tracker.Current == null || !Tracker.Current.IsActive) return false;

        if (Tracker.Current.Contact.IsNew) return true;

        return false;
    }
}

To check a contacts previous interactions, you need to call XConnect directly. A condition as below should satisfy your requirements:

public class IsNewUserCondition<T> : WhenCondition<T> where T : RuleContext
{
    protected override bool Execute(T ruleContext)
    {
        if (Tracker.Current == null || !Tracker.Current.IsActive) return false;

        using (Sitecore.XConnect.Client.XConnectClient client = Sitecore.XConnect.Client.Configuration.SitecoreXConnectClientConfiguration.GetClient())
        {
            var references = new List<Sitecore.XConnect.IEntityReference<Sitecore.XConnect.Contact>>()
                {
                    new IdentifiedContactReference(Sitecore.Analytics.XConnect.DataAccess.Constants.IdentifierSource, Sitecore.Analytics.Tracker.Current.Contact.ContactId.ToString("N"))
                };

            var contacts = client.Get<Sitecore.XConnect.Contact>(references, new ContactExecutionOptions(new Sitecore.XConnect.ContactExpandOptions(PersonalInformation.DefaultFacetKey)
            {
                Interactions = new Sitecore.XConnect.RelatedInteractionsExpandOptions(LocaleInfo.DefaultFacetKey)
                {
                    StartDateTime = DateTime.MinValue,
                    EndDateTime = DateTime.UtcNow.AddDays(-30),
                    Limit = 1
                }
            }));
            if (!contacts.FirstOrDefault().Entity.Interactions.Any()) return true;
            return false;
        }
    }
}

These conditions have been tested and work on Sitecore 10.1 XP.
