Just in case this ever comes up for someone else, here's how I solved this. I had to post an empty string to the page. If you note the lines:
If RequestMethod = "POST" And Not IsNothing(Data) Then objRequest.ContentLength = Data.Length Dim objWriter As New StreamWriter(objRequest.GetRequestStream) objWriter.Write(Data.ToString) objWriter.Close() End If I was sending Nothing in the Data, so it was not writing to the request stream. When I changed that and started writing an empty string in the request stream I started to get the response back. -- Twitter developer documentation and resources: http://dev.twitter.com/doc API updates via Twitter: http://twitter.com/twitterapi Issues/Enhancements Tracker: http://code.google.com/p/twitter-api/issues/list Change your membership to this group: http://groups.google.com/group/twitter-development-talk
