In our site I am trying to integrate the CITI Bank payment gateway .For canceling a payment we need to send the post request from merchant site to payment gateway site .For this I am using the web request method , I am posting the parameters to the payment gateway server using the web request but not getting the web response , it is giving the error as The remote server returned an error: (500) Internal Server Error . I am not understanding whether the problem is with the web request or I am not sending the request properly to the gateway . Can anyone please let me know is there any other way to post the request from server to server other than web request method .
The remote server returned an error: (500) Internal Server Error
If you are sending web request as per their code functionality then its not your error.Sometimes if you are not sending all the parameters which the gateway needs then this error may occur..!
Sometimes the http request waits for particular time to get the response from the server and if it did not get any response this error may occur..!
Here is the sample method for authorize .net for gateway hope it helps..!
private string CreditCardCheck()
String strPost = "x_login=" + loginID + "&x_tran_key=" + trans_Key ;
StreamWriter myWriter = null;
string url ="https://secure.authorize.net/gateway/transact.dll";
HttpWebRequest objRequest = (HttpWebRequest)WebRequest.Create(url);
objRequest.Method = "POST";
objRequest.ContentLength = strPost.Length;
objRequest.ContentType = "application/x-www-form-urlencoded";
myWriter = new StreamWriter(objRequest.GetRequestStream());
catch (Exception ex)
HttpWebResponse objResponse = (HttpWebResponse)objRequest.GetResponse();
using (StreamReader sr =
result = sr.ReadToEnd();
string responsedetails = result.Split('|');
TrasactionId = responsedetails.ToString();
// Close and clean up the StreamReader
if (result.ToLower().Contains("invalid") || result.ToLower().Contains("inactive"))
return "CreditCardis notvalid";
return TrasactionId ;
