I've been tasked with using zoho support for our ticketing system.  As I try to add zoho into our existing web form I have come across an issue.  I really want to use zoho since we plan to use the CRM as well, but I can't get this simple task to work.

Typically when submitting xml data I'd use something like this:

2. Dim req As System.Net.WebRequest = Nothing
3.         Dim rsp As System.Net.WebResponse = Nothing
4.         Dim Request As String = ""
5.         Request = Request & "authtoken=MyAuthToken&portal=PortalName&department=Support&xml="
6.         Request = Request & "<requests>"
7.         Request = Request & "<row no=""1"">"
8.         Request = Request & "<fl val=""Subject"">Support Request</fl>"
9.         Request = Request & "<fl val=""Contact Name"">" & tbFirstName.Text & " " & tbLastName.Text & "</fl>"
10.         Request = Request & "<fl val=""Product Name"">" & tbCompanyName.Text & "</fl>"
11.         Request = Request & "<fl val=""Email"">" & tbEmail.Text & "</fl>"
12.         Request = Request & "<fl val=""Phone"">" & tbPhone.Text & "</fl>"
13.         Request = Request & "<fl val=""Description"">" & tbDescription.Text & "</fl>"
14.         Request = Request & "</row>"
15.         Request = Request & "</requests>"
16.         Try
17.             Dim url As String = "https://support.zoho.com/api/xml/requests/addrecords?"
18.             req = System.Net.WebRequest.Create(url)
19.             req.Method = "POST"
20.             req.ContentType = "text/xml"
21.             Dim writer As New System.IO.StreamWriter(req.GetRequestStream())
22.             writer.WriteLine(Request)
23.             writer.Close()
24.             rsp = req.GetResponse()
25.         Catch
26.             Throw
27.         Finally
28.             If req IsNot Nothing Then
29.                 req.GetRequestStream().Close()
30.             End If
31.             If rsp IsNot Nothing Then
32.                 rsp.GetResponseStream().Close()
33.             End If
34.         End Try

I always get a 400 Bad Request error.  When I manually type in the url along with the xml data I can create tickets just fine.  Is there some way to add a record from code behind in .net?  I need a good example please!
