What is the best way to accept a credit card in ASP.NET? (Between ASP.NET and Authorize.NET)

I'm new to creating commerce websites, and now that I need to sell software over the internet, I'm not sure where to start.

I'm using ASP.NET and am considering using Authorize.NET to validate and process the credit cards.

I'm looking for a stable, trusted solution that I can install on a single server. My secondary goal (besides selling products online) is to become familiar with shopping cart software that is popular, and in use by large businesses. Perhaps I should start with MS Commerce server?

Authorize.Net is Very easy to implement with ASP.NET

Basically you can make transaction in 3-4 ways:

  1. Simple Checkout Through Button like Paypal (http://developer.authorize.net/api/simplecheckout/)
  2. Direct Post : Suppose you little bit more customization than Simple CheckOut. Create a checkout form that posts directly to Authorize.Net http://developer.authorize.net/api/simplecheckout/

Eg:

<h1><%=ViewData["message"] %></h1>
<%using (Html.BeginSIMForm("http://YOUR_SERVER.com/home/sim",
1.99M,"YOUR_API_LOGIN","YOUR_TRANSACTION_KEY",true)){%>
<%=Html.CheckoutFormInputs(true)%>
<%=Html.Hidden("order_id","1234") %>
<input type = "submit" value = "Pay" />
<%}%>
  1. SIM (Server Integration)
  2. AIM (Advance Integration Method): Give full control & customization.
  3. CIM ( store Customer card no & info on Auth.NET server with tokanization)

*Below is a sample of CIM function to make a transaction, AIM is very much similar to CIM only difference is tokanization *

using ProjName.AuthApiSoap;  // USE AUth Webserice Reference

   public Tuple<string, string, string> CreateTransaction(long profile_id, long payment_profile_id, decimal amt, string DDD)
        {
            CustomerProfileWS.ProfileTransAuthCaptureType auth_capture = new CustomerProfileWS.ProfileTransAuthCaptureType();
            auth_capture.customerProfileId = profile_id;
            auth_capture.customerPaymentProfileId = payment_profile_id;
            auth_capture.amount = amt;//1.00m;
            auth_capture.order = new CustomerProfileWS.OrderExType();
            POSLib.POSManager objManager = new POSLib.POSManager();
            auth_capture.order.invoiceNumber = objManager.GetTimestamp(DateTime.Now);
            DateTime now = DateTime.Now;
            auth_capture.order.description = "Service  " + DDD;
            CustomerProfileWS.ProfileTransactionType trans = new CustomerProfileWS.ProfileTransactionType();
            trans.Item = auth_capture;
            CustomerProfileWS.CreateCustomerProfileTransactionResponseType response = SoapAPIUtilities.Service.CreateCustomerProfileTransaction(SoapAPIUtilities.MerchantAuthentication, trans, null);

            string AuthTranMsg = "";
            string AuthTranCode = "";
            for (int i = 0; i < response.messages.Length; i++)
            {
                AuthTranMsg = response.messages[i].text;  // To Get Message n for loop to check the [i] is not empty 
            }
            for (int i = 0; i < response.messages.Length; i++)
            {
                AuthTranCode = response.messages[i].code;   // To Get Code n for loop to check the [i] is not empty 
            }
            var tCompResp = new Tuple<string, string, string>(AuthTranCode, AuthTranMsg, response.directResponse);
            return tCompResp;
        }

This is how to split the Reponse Msg (Format and Order will be FIXED for all transaction/ on web service responsed )

 var tResp = objManager.CreateTransaction(profID, paymProfID, Convert.ToDecimal(PmtToday), DDD);
                    string respCCNo = "";
                    string RespCCType = "";
                    string InvoiceNo = "";
                    string transType = "";
                    string approvalCode = "";
                    string AmtRequested = "";
                    string respName = "";
                    string respReasonText = "";
                    string respMD5Hash = "";
                    string respEmailId = "";
                    string respReasonCode = "";
                    string respMethod = "";
                    string respAVSResultCode = "";
                    string responseCode = "";
                    string transactionId = "0";
                    if (!string.IsNullOrEmpty(tCompResp.Item3))
                    {
                        string[] arrRespParts = tCompResp.Item3.Replace("|", "").Split(',');
                        responseCode = arrRespParts[0];
                        respReasonCode = arrRespParts[2];
                        respReasonText = arrRespParts[3];
                        approvalCode = arrRespParts[4];
                        respAVSResultCode = arrRespParts[5];
                        transactionId = arrRespParts[6].Replace("|", "");
                        InvoiceNo = arrRespParts[7];
                        AmtRequested = arrRespParts[9];
                        transType = arrRespParts[10];
                        respMethod = arrRespParts[11];
                        respName = arrRespParts[13] + " " + arrRespParts[14];
                        respEmailId = arrRespParts[23];
                        respMD5Hash = arrRespParts[37];
                        respCCNo = arrRespParts[50];
                        RespCCType = arrRespParts[51];
                    }

There are a million options here, but if you are writing the code, the easiest way code-wise is to use http://sharpauthorize.com/
