POST or GET method?

We have a service provider that allows us to connect to his payment page for payments, however the code he uses is php but we would like to do it in asp.net.

Problem is I don't really understand what the method should be, POST or GET, basically we need to redirect to the client with underlying parameters(not query strings) and then our current page that calls the request must be redirected to the client page with the parameters as well.

I do get the response witch is basically markup, but that's not what I want, I want it to redirect to the payment page, can someone please tell me what I do wrong.Thanks Here is my code I use for the POST Method:

string query = string.Format("description={0}&amount={1}&merchantIdent={2}&email={3}&transaction={4}&merchantKey={5}",
                             description.ToString(), amount.ToString(), merchantIdent.ToString(), email.ToString(), id.ToString(), merchantKey.ToString());

// Create the request back
string url = "https://www.webcash.co.za/pay";
HttpWebRequest req = (HttpWebRequest)WebRequest.Create(url);

req.Method = "POST";
req.AllowAutoRedirect = true;
req.ContentType = "application/x-www-form-urlencoded";
req.ContentLength = query.Length;
req.AllowAutoRedirect = true;

StreamWriter stOut = new StreamWriter(req.GetRequestStream(),System.Text.Encoding.ASCII);
stOut.Write(query);
stOut.Close();

// Do the request
StreamReader stIn = new StreamReader(req.GetResponse().GetResponseStream());
string response = stIn.ReadToEnd();
stIn.Close();

Normally GETs are idempotent (meaning they don't change data). Use a GET if you want to be able to issue a request and not change anything. Use a POST if you're performing some sort of update/processing/etc.

Not sure I totally understand your question, but as your title goes, here is the difference between POST and GET: The GET method passes variables through the url. This can be practical or impractical (for instance if you plan to pass sensitive material to another page) The POST method does not pass variables through the url, it passes the variables behind the scenes. You'll need to decide which better fits your situation.
