Looks like I got this one. Here is the code I was falling all over. This is simplistic and without web.config for now: First Create a button on anyold aspx page. Now go to the code behind and add: <!---------------Syntax Starts Here--------------------------------------> using System;
using System.Data;
using System.Configuration;
using System.Collections;
using System.Web;
using System.Web.Security;
using System.Web.UI;

using System.Web.UI.HtmlControls; using System.Net;
using System.Text;
using System.IO;
using System.Text.RegularExpressions; public partial class vps_home : System.Web.UI.Page

string PWD = "xxx";
string USER= "xxx";
string VENDOR="xxx";
string PARTNER = "xxx"; //3. now create the name value pair string to send to the Payflow servers
