I am trying to connect to a web service using asp post
 Set objHTTP =  CreateObject("WinHttp.WinHttpRequest.5.1")
vPostData = "op=ValidateTinName&TIN=" & request.form("taxid") & "&LName="  & request.form("Name") & "&UserLogin=*****g&UserPassword=***#"
objHTTP.Open "POST", "https://www.****", false
objHTTP.Send  vPostData
response.write(objHTTP.ResponseText)

Open in new window

I am getting an error " Data at the root level is invalid."
The page is asking for xml is different levels. How would I change my postdata to represent that.
 <ValidateTinName xmlns="******">
      <TinName>
        <TIN>string</TIN>
        <LName>string</LName>
        <FName>string</FName>
        <Encryption>string</Encryption>
      </TinName>
      <CurUser>
        <UserID>string</UserID>
        <UserLogin>string</UserLogin>
        <UserPassword>string</UserPassword>
        <UserEncryption>string</UserEncryption>
      </CurUser>
    </ValidateTinName>
  </soap:Body>
</soap:Envelope>

This is a soap call.  You have to post the entire envelope.   For other languages like php and ruby, there are libraries to make this easy.  For those of us using ASP, we have to take the long way and convert the envelope (XML) to a string and post the string.    If you are using variable, place them in the xml as I have sampled.

if request.form("TIN")<>"" then ' test for data
     TIN=request.form("TIN")
     else
     TIN=""  ' make sure to not send null data
end if

theXML="<ValidateTinName xmlns=""******"">"  ' notice double quotes
theXML=theXML&"<TinName>"
theXML=theXML&"<TIN>"&TIN&"</TIN>"
       ' do this for each node
theXML=theXML&"</soap:Envelope>"

Set objHTTP =  CreateObject("WinHttp.WinHttpRequest.5.1")
vPostData = theXML
objHTTP.Open "POST", "https://www.****", false
objHTTP.Send  vPostData
response.write(objHTTP.ResponseText)

I fixed up the whole xml envelope.

What's with this error now?

The server cannot service the request because the media type is unsupported.
