Valid XML for Publishing to QuickBooks Online Edition - Getting (400) Query Error

Question

I am trying to post below xml https://apps.quickbooks.com/j/AppGateway and all I get is an error: the remote server returned an error: (error 400, invalid request. Does anyone have any idea that I am I doing wrong? Below is the C # code that I use to publish xml.

Thanks, Jeff

UPDATE: to add more to my question, I think the (400) Bad Request error indicates that I have something very bad with xml or with the way I submit xml. That's why I ask this question ... what am I missing here?

<?xml version="1.0" encoding="utf-8" ?>
<?qbxml version="7.0"?>
<QBXML>
<SignonMsgsRq>
<SignonDesktopRq>
<ClientDateTime>7/20/2009 12:36PM</ClientDateTime>
<ApplicationLogin>APP_LOGIN</ApplicationLogin>
<ConnectionTicket>CONNECTION_TICKET</ConnectionTicket>
<Language>English</Language>
<AppID>APP_ID</AppID>
<AppVer>1</AppVer>
</SignonDesktopRq>
</SignonMsgsRq>
<QBXMLMsgsRq>
<CustomerQueryRq requestID="2" />
</QBXMLMsgsRq>
</QBXML>



WebRequestObject = (HttpWebRequest)WebRequest.Create(requestUrl);
WebRequestObject.Method = "POST";
WebRequestObject.ContentType = "application/x-qbxml";
WebRequestObject.AllowAutoRedirect = false;
string post = XmlText.Text;

WebRequestObject.ContentLength = post.Length;

swr = new StreamWriter(WebRequestObject.GetRequestStream());
swr.Write(post);
swr.Close();

WebResponseObject = (HttpWebResponse)WebRequestObject.GetResponse();
