In this post we will learn how to get response from
Authorize.Net credit card payment using ASP.NET MVC4
One of my client projects I need to implement Authorize.net
payment gateway. So just implemented using SIM (Server Integration Method). But
my client wants, if the payment getting success then shown a custom receipt
page and save the transaction details in to our own database. In other case if the
payment getting fail then provides repayment option.
In SIM method this is not possible (or not advisable) because
we using “x_relay_response” to get response from Authorize.net. Note,this is just relay the url, not redirect to the result page. And URL always points to
the https://test.authorize.net/gateway/transact.dll.
And the response time also only 10 seconds. If your server not responds within
10 seconds then you get time out error like
“An error occurred while trying to report this transaction
to the merchant. An email has been sent to the merchant informing them of the
error. The following is a result of the attempt to charge your credit card.”
This error indicates that Authorize.Net is unable to connect
to the page that you have specified as your relay response URL. To avoid this
kind of errors you need to go with Authorize.net’s another one integration
method AIM (Advanced Integration Method)
You can get more about AIM method from here http://www.authorize.net/support/AIM_guide.pdf
Implement AIM :
First create a sandbox account in Authorize.Net. https://developer.authorize.net/sandbox/. After you registered you will get the API Credentials
API Login ID
Transaction Key
Secret Question
Create you view page as per your requirement. Here I'm taking from Authorize.net default payment screen

Then add that details into your web.config file
<!-- Payment Authorize.NET - Begins -->
<add key="Payment.AuthLoginID" value="XXXXXXXXXX" />
<add key="Payment.AuthTransactionKey" value="XXXXXXXXX" />
<add key="Payment.TestMode" value="true" />
<add key="Payment.URL" value="https://test.authorize.net/gateway/transact.dll" />
<!--<add key="Payment.URL" value="https://secure.authorize.net/gateway/transact.dll" />-->
<!-- Payment Authorize.NET - End -->
Then call the following function into your post method
private string AuthorizePayment(PaymentDataModel payDataModel) { string AuthNetVersion = "3.1"; // Contains CCV support string AuthNetLoginID = System.Configuration.ConfigurationManager.AppSettings["Payment.AuthLoginID"].ToString(); string AuthNetTransKey = System.Configuration.ConfigurationManager.AppSettings["Payment.AuthTransactionKey"].ToString(); string AuthNetMode = System.Configuration.ConfigurationManager.AppSettings["Payment.TestMode"].ToString(); WebClient objRequest = new WebClient(); System.Collections.Specialized.NameValueCollection objInf = new System.Collections.Specialized.NameValueCollection(30); System.Collections.Specialized.NameValueCollection objRetInf = new System.Collections.Specialized.NameValueCollection(30); byte[] objRetBytes; string[] objRetVals; string retMessage; objInf.Add("x_version", AuthNetVersion); objInf.Add("x_delim_data", "True"); objInf.Add("x_login", AuthNetLoginID); // objInf.Add("x_password", AuthNetPassword); objInf.Add("x_tran_key", AuthNetTransKey); objInf.Add("x_relay_response", "False"); // Switch this to False once you go live objInf.Add("x_test_request", AuthNetMode); objInf.Add("x_delim_char", ","); objInf.Add("x_encap_char", "|"); // Billing Address objInf.Add("x_first_name", payDataModel.FirstName); objInf.Add("x_last_name", payDataModel.LastName); objInf.Add("x_address", payDataModel.Address); objInf.Add("x_city", payDataModel.City); objInf.Add("x_state", payDataModel.State); objInf.Add("x_zip", payDataModel.ZIP); objInf.Add("x_country", payDataModel.Country); objInf.Add("x_email", payDataModel.Email); objInf.Add("x_fax", payDataModel.Fax); objInf.Add("x_phone", payDataModel.Phone); objInf.Add("x_description", payDataModel.Description); // Card Details objInf.Add("x_card_num", payDataModel.CardNumber); objInf.Add("x_exp_date", payDataModel.CardExpiryDate); // Authorisation code of the card (CCV) objInf.Add("x_card_code", payDataModel.CCV); objInf.Add("x_method", "CC"); objInf.Add("x_type", "AUTH_CAPTURE"); objInf.Add("x_amount", payDataModel.Amount); // Currency setting. Check the guide for other supported currencies objInf.Add("x_currency_code", "USD"); try { // Pure Test Server objRequest.BaseAddress = System.Configuration.ConfigurationManager.AppSettings["Payment.URL"].ToString().Trim(); objRetBytes = objRequest.UploadValues(objRequest.BaseAddress, "POST", objInf); objRetVals = System.Text.Encoding.ASCII.GetString(objRetBytes).Split(",".ToCharArray()); if (objRetVals[0].Trim(char.Parse("|")) == "1") { // Returned Authorisation Code ViewBag.AuthNetCode = objRetVals[4].Trim(char.Parse("|")); // Returned Transaction ID ViewBag.AuthNetTransID = objRetVals[6].Trim(char.Parse("|")); return retMessage = "1"; } else { // Error! retMessage = objRetVals[3].Trim(char.Parse("|")) + " (" + objRetVals[2].Trim(char.Parse("|")) + ")"; if (objRetVals[2].Trim(char.Parse("|")) == "44") { // CCV transaction decline retMessage += "Our Card Code Verification (CCV) returned the following error: "; switch (objRetVals[38].Trim(char.Parse("|"))) { case "N": retMessage += "Card Code does not match."; break; case "P": retMessage += "Card Code was not processed."; break; case "S": retMessage += "Card Code should be on card but was not indicated."; break; case "U": retMessage += "Issuer was not certified for Card Code."; break; } } if (objRetVals[2].Trim(char.Parse("|")) == "45") { if (retMessage.Length > 1) retMessage += "<br />n"; // AVS transaction decline retMessage += "Our Address Verification System (AVS) returned the following error: "; switch (objRetVals[5].Trim(char.Parse("|"))) { case "A": retMessage += " the zip code entered does not match the billing address."; break; case "B": retMessage += " no information was provided for the AVS check."; break; case "E": retMessage += " a general error occurred in the AVS system."; break; case "G": retMessage += " the credit card was issued by a non-US bank."; break; case "N": retMessage += " neither the entered street address nor zip code matches the billing address."; break; case "P": retMessage += " AVS is not applicable for this transaction."; break; case "R": retMessage += " please retry the transaction; the AVS system was unavailable or timed out."; break; case "S": retMessage += " the AVS service is not supported by your credit card issuer."; break; case "U": retMessage += " address information is unavailable for the credit card."; break; case "W": retMessage += " the 9 digit zip code matches, but the street address does not."; break; case "Z": retMessage += " the zip code matches, but the address does not."; break; } } // strError contains the actual error ViewBag.ErrorMsg = retMessage; return retMessage; } } catch (Exception ex) { return retMessage = ex.Message; } }
