C# wrapper .Net library - Constant 500 errors

[JLandon]

Hi.. I'm trying to use the .Net Library. My authentication works but I keep getting 500 errors.

What is wrong with the following. Do you have any .Net library samples?    thanks in advance

AuthenticationData authdata = new AuthenticationData();authdata.Username = "USER";



authdata.Password = "PASS";



authdata.ApiKey = "KEY";



ContactList c = new ContactList("TEST",true);



c.SortOrder = 999;



c.Id = "9";

string uri = " https://api.constantcontact.com/ws/customers/"+ USER+ /activities";      <-- IS THIS CORRECT?

StringBuilder sb =

ConstantContactUtility.Components.ContactListComponent.CreateNewContactList(c);















Utility.httpPost(authdata,uri, sb.ToString());
