Payflow gateway and Payment Advanced - paypal

Question

I want to test PayPal Payment Advanced on my site an use this:https://ppmts.custhelp.com/app/answers/detail/a_id/929/. Now I finished intergrating it with my site. But now I can pay with PayPal Account, I failed to get payment with a Credit Card, I can't get any wrong response from PayPal when I use this API. This is my Code:
public NameValueCollection PayAdvanced(VM_BasketOrder basketOrder)
{
string baseUrl = Request.Url.Scheme + "://" + Request.Url.Authority;
string ReturnURL = baseUrl + Url.Action("ReturnPayAdvanced", "ShoppingCart");
string CancelURL = baseUrl + Url.Action("CancelPay", "ShoppingCart");
StoredAddress billAddress = basketOrder.billto_sAddress;
StoredAddress shipAddress = basketOrder.shipto_sAddress;
NameValueCollection requestArray = new NameValueCollection()
{
{"PARTNER", "PayPal"},
{"VENDOR", "s04124226"},
{"USER", "g041234226"},
{"PWD", "k_123452346789"},
{"CREATESECURETOKEN", "Y"},
{"SECURETOKENID", genId()},
{"TRXTYPE", "S"},//A
{"SHIPAMOUNT", basketOrder.ShippingAmount.ToString()},
{"AMT", basketOrder.Total.ToString()},
{"TAX", basketOrder.SalesTax.ToString()},
// {"ACCT","4111111111111111"},
// {"EXPDATE","1215"},
{"CURRENCY", "USD"},
//{"SILENTTRAN","TRUE"},
{"RETURNURL", ReturnURL},
{"CANCELURL", CancelURL},
{"ERRORURL", CancelURL},
{"BILLTOFIRSTNAME",billAddress.Name.AddressNameSplit()[0]},
{"BILLTOLASTNAME", billAddress.Name.AddressNameSplit()[1]},
{"BILLTOSTREET", billAddress.Street1},
{"BILLTOCITY",billAddress.City},
{"BILLTOSTATE",billAddress.State},
{"BILLTOZIP",billAddress.Zip},
{"BILLTOCOUNTRY",billAddress.Country},
{"BILLTOPHONE","55555"},
{"SHIPTOFIRSTNAME", shipAddress.Name.AddressNameSplit()[0]},
{"SHIPTOLASTNAME", shipAddress.Name.AddressNameSplit()[1]},
{"SHIPTOSTREET", shipAddress.Street1},
{"SHIPTOCITY", shipAddress.City},
{"SHIPTOSTATE", shipAddress.State},
{"SHIPTOZIP",shipAddress.Zip},
{"SHIPTOCOUNTRY",shipAddress.Country},
{"SHIPTOPHONE","55555"},
};
NameValueCollection resp = run_payflow_call(requestArray);
return resp;
}
protected NameValueCollection run_payflow_call(NameValueCollection requestArray)
{
#region send request to Payflow
String nvpstring = "";
foreach (string key in requestArray)
{
//format: "PARAMETERNAME[lengthofvalue]=VALUE&". Never URL encode.
var val = requestArray[key];
nvpstring += key + "[ " + val.Length + "]=" + val + "&";
}
string urlEndpoint = "https://pilot-payflowpro.paypal.com/";
HttpWebRequest payReq = (HttpWebRequest)WebRequest.Create(urlEndpoint);
payReq.Method = "POST";
payReq.ContentLength = nvpstring.Length;
payReq.ContentType = "application/x-www-form-urlencoded";
StreamWriter sw = new StreamWriter(payReq.GetRequestStream());
sw.Write(nvpstring);
sw.Close();
#endregion
#region get Payflow response
HttpWebResponse payResp = (HttpWebResponse)payReq.GetResponse();
StreamReader sr = new StreamReader(payResp.GetResponseStream());
string response = sr.ReadToEnd();
sr.Close();
#endregion
#region parse string into array and return
NameValueCollection dict = new NameValueCollection();
foreach (string nvp in response.Split('&'))
{
string[] keys = nvp.Split('=');
dict.Add(keys[0], keys[1]);
}
return dict;
#endregion
}
protected string genId()
{
var chars = "ABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789";
var random = new Random();
var result = new string(
Enumerable.Repeat(chars, 16)
.Select(s => s[random.Next(s.Length)])
.ToArray());
return "MySecTokenID-" + result; //add a prefix to avoid confusion with the "SECURETOKEN"
}
I use this code, and I get passed a tokenid and token to next code.
<iframe src="#("https://payflowlink.paypal.com?MODE=TEST&SECURETOKENID="+ViewBag.SECURETOKENID+"&SECURETOKEN="+ViewBag.SECURETOKEN)" name="test_iframe" scrolling="no" style=" width:480px;height:490px;border:0px;"></iframe>
I get the PayPal iframe on my site, click the PayPal button, I can pay successfully, but when I enter a credit card number and click "pay now", I can't get money in my test account. Now I don't know how to debug my code, because it is executiin in PayPal, so I can't find where the mistake is in my code. So I pasted my code here, and hope some can help me.
today I find, when I use credit card pay, PNREF=V72A4DR7AE07, I can't get PPREF. when I use PayPal Account to pay, I can get PNREF and PPREF all. And PPREF is the PayPal transactionId.
