How To: Integrate Credit Card and ACH (e-check) processing into a Flex / Actionscript Flash system

This is the eighth part in a series of postings on how to integrate credit card and ACH/E-check transactions into various systems. This installment demonstrates code used for processing payments (credit card and/or ACH) within a Flex / ActionScript Flash application.

This was taken from the NELiX TransaX FleXport toolkit documentation. Credit card integration examples can be downloaded on the NELiX TransaX FleXport page.

Assumptions:
- Using NELiX TransaX Payment Gateway
- Communicating using NELiX TransaX Webservice

Follow these steps.

1. Create a new project.

2. Open “Data->Import Web Service” menu

3. Change port to “RoXAIPSoap”and click “Finish”.
WebService files will be generated automatically.

4. Add import directives in your project:

   import com.nelixtransax.Responses;
   import com.nelixtransax.Params;
   import com.nelixtransax.ProcessTransaction_request;
   import com.nelixtransax.ProcessTransactionResultEvent;
   import com.nelixtransax.RoXAPI;

5. Initialize WebService:

   private var ws:RoXAPI = new RoXAPI(null, null);

6. Add event listeners:

   private function OnNelixWSButtonClick():void
   {
ws.addEventListener(ProcessTransactionResultEvent.ProcessTransaction_RESULT, OnNelixWSSucces);
  
     var params:Params = new Params();
     var token:AsyncToken = ws.processTransaction(params);
     token.addEventListener(FaultEvent.FAULT, OnFault);
   }

   private function OnNelixWSSucces(event:ProcessTransactionResultEvent):void
   {
     var a:com.nelixtransax.Responses = ws.processTransaction_lastResult;
     Alert.show("Succes!");
   }

   private function OnFault(event:FaultEvent):void
   {
    Alert.show("Error #" + event.fault.errorID.toString() + ": " + event.fault.message );
   }

7. Fill parameters:

   private function FillParams(wsParams:Params):void
   {
     wsParams.TransactionType = TransactionType.selectedItem.toString();
     wsParams.GatewayUserName = GatewayUserName.text;
     wsParams.GatewayPassword = GatewayPassword.text;
     wsParams.IPAddress = "127.0.0.1";

     wsParams.Merchant_Defined_Field_1 = Merchant_Defined_Field_1.text;
     wsParams.Merchant_Defined_Field_2 = Merchant_Defined_Field_2.text;

     if(TransactionType.selectedItem.toString() == "void")
       wsParams.TransactionID = TransactionID.text;     

     if(TransactionType.selectedItem.toString() == "refund")
     {
       wsParams.Amount = Amount.text;
       wsParams.TransactionID = TransactionID.text;
     }

     if (TransactionType.selectedItem.toString() == "capture" )
     {
       wsParams.Amount = Amount.text;
       wsParams.TransactionID = TransactionID.text;
       wsParams.OrderID = OrderID.text;
       wsParams.Tracking_Number = Tracking_Number.text;
       wsParams.Shipping_Carrier = Shipping_Carrier.text;
     }

     if (TransactionType.selectedItem.toString() == "update")
     {
       wsParams.TransactionID = TransactionID.text;
       wsParams.Tracking_Number = Tracking_Number.text;
       wsParams.Shipping_Carrier = Shipping_Carrier.text;
     }

     if (Customer_Vault_Action.selectedItem.toString() == "delete_customer")
     {
       wsParams.Customer_Vault_Action = Customer_Vault_Action.selectedItem.toString();
       wsParams.Customer_Vault_ID = Customer_Vault_ID.text;
     }

     if(TransactionType.selectedItem.toString() == "sale" || TransactionType.selectedItem.toString() == "auth" || Customer_Vault_Action.selectedItem.toString() == "add_customer" || Customer_Vault_Action.selectedItem.toString() == "update_customer" )
     {
       wsParams.PaymentType = PaymentType.selectedItem.toString();

       if(Customer_Vault_Action.selectedItem.toString() == "add_customer" || Customer_Vault_Action.selectedItem.toString() == "update_customer" )
       {
         wsParams.Customer_Vault_Action = Customer_Vault_Action.selectedItem.toString();
       }
       wsParams.Customer_Vault_ID = Customer_Vault_ID.text;

       if (wsParams.PaymentType == "creditcard")
       {
         wsParams.CCNumber = CCNumber.text;
         wsParams.CCExpDate = CCExpDate.text;
         wsParams.CVV = CVV.text;
       }
       if(wsParams.PaymentType == "check")
       {
         wsParams.CheckName = CheckName.text;
         wsParams.CheckABA = CheckABA.text;
         wsParams.CheckAccount = CheckAccount.text;
         wsParams.AccountHolderType = AccountHolderType.selectedItem.toString();
         wsParams.AccountType = AccountType.selectedItem.toString();
         wsParams.SecCode = SecCode.selectedItem.toString();
       }

       wsParams.Payment_Plan_SKU = Payment_Plan_SKU.text;

       wsParams.Amount = Amount.text;
       wsParams.Tax = Tax.text;
       wsParams.Shipping = Shipping.text;
       wsParams.OrderDescription = OrderDescription.text;
       wsParams.OrderID = OrderID.text;
       wsParams.PONumber = PONumber.text;

       wsParams.FirstName = FirstName.text;
       wsParams.LastName = LastName.text;
       wsParams.Company = Company.text;
       wsParams.Address1 = Address1.text;
       wsParams.Address2 = Address2.text;
       wsParams.City = City.text;
       wsParams.State = State.text;
       wsParams.Zip = Zip.text;
       wsParams.Country = Country.text;
       wsParams.Phone = Phone.text;
       wsParams.Fax = Fax.text;
       wsParams.EMail = EMail.text;
       wsParams.Website = Website.text;

       wsParams.ShippingFirstName = ShippingFirstName.text;
       wsParams.ShippingLastName = ShippingLastName.text;
       wsParams.ShippingCompany = ShippingCompany.text;
       wsParams.ShippingAddress1 = ShippingAddress1.text;
