                }
            }
        }
    }
}

Edit the CERTIFICATE_THUMBPRINT, XCONNECT_URL, and CONTACT IDENTIFIER constants.
Save the Program.cs file.
Press F5 to run the app. If the connection is established, the app writes the following in the terminal:
- The contact ID.
- The contact name.

Important

To retrieve a facet, you must explicitly request it as part of ContactExpandOptions. If you run the code without ContactExpandOptions the facet becomes NULL, and you get an exception error when you try to use it.

Note

External systems are not normally used for storing contact IDs, so it is unlikely that you will use the .Get<Contact> overload that accepts a contact ID.

Get a contact's interactions

To get a contact's interactions, you must set the Interactions property of ContactExpandOptions.

To get a contact's interactions:

In Visual Studio, in Solution Explorer, double-click the Program.cs file and replace the content with the following code:

}

Edit the CERTIFICATE_THUMBPRINT, XCONNECT_URL, and CONTACT IDENTIFIER constants.
Save the Program.cs file.
Press F5 to run the app. If the connection is established, the app writes the following in the terminal:
- The contact ID.
- The contact name.
- The number of interactions.
- The business name of each interaction.

Tip

You can adjust the StartDateTime and EndDateTime properties to retrieve only interactions between these two points in time.
You can set the Limit property to the number of interactions you want to see (counting from the first interaction).

Get an interaction

To get an interaction, you must have the contact ID and the interaction ID. You can also pass InteractionExpandOptions that gets the related contact and any contact facets you specify.

To get an interaction, use the following code:

RequestResponse

var contactId = Guid.NewGuid();
var interactionId = Guid.NewGuid();

InteractionReference interactionReference = new InteractionReference(contactId, interactionId);

Interaction interaction = client.Get<Interaction>(
    interactionReference,
    new InteractionExpandOptions(new string[] { IpInfo.DefaultFacetKey })
    {
        Contact = new RelatedContactExpandOptions(new string[] { 
            PersonalInformation.DefaultFacetKey
        })
    }
);

Go to the next walkthrough to learn how to search contacts and interactions.
