I don't understand why the results aren't returning a first name. Or results of any kind. I was under the impression the ['firstname'] in the properties param would mean the firstname of the contact object matching the query would be returned.
To access the next page of results, you must pass the after parameter provided in the paging.next.after property of the previous response. If the paging.next.after property isn’t provided, there are no additional results to display. Note: The after parameter is expected to be a string.
