Request contact list information using a specific property
    You can request the user's contact information for contacts that return specific properties (for example, only the first name of the contacts). In the following sample code, 
BEMS
 requests the first name of all the contacts in the user's contact folder. The response includes up to 50 contacts. If the client provides a FolderId, BEMS
 requests the contacts from the specific folder.
        POST https://localhost:8443/api/contact HTTP/1.1 Content-Type: application/json X-Good-GD-AuthToken: <GDAuthToken> { "Account": "jamie01@ex365.example.com", "MaxNumber": 50, "Offset": 0, "UserShape": ["FirstName"], "FolderId": "AQMkADk0YzU4MjdkLWU1YjktNGE0OC1iZDczKI0Kuc7BmRwA..."" (optional) }
If the request is successful, 
BEMS
 returns the following response, and the third-party BlackBerry
        Dynamics
 apps display the first name of the contacts.
