FDMSRcDebit Control

Properties Methods Events Configuration Settings Errors

The FDMSRcDebit component is an advanced tool used to authorize debit cards in a Retail environment, where the customer is purchasing products or services in person. This component makes authorizing debit card transactions with a customer PIN very easy.

Syntax

FDMSRcDebit

Remarks

This control connects to the First Data Merchant Services (FDMS) processor, by way of the Datawire VXN transaction transport network. Transactions originating with these controls go through Datawire, to the FDMS processor where the transaction is authorized. The result is then returned back through Datawire and received by the control. This control can be integrated into web pages or stand-alone Point Of Sale applications. Because all SSL communications are handled inside the control, any application or web page can be deployed without the need for expensive dedicated SSL servers.

The FDMSRcDebit control makes authorizing debit transactions (where the customer is present and inputs his/her PIN number) very easy by adding an additional layer of abstraction between the programmer and the protocol. There is no need to deal with raw sockets, TLS/SSL handshakes, or data packet formatting. The steps to setting up the control and sending transactions are outlined below:

Datawire Setup

First, you must register and activate your account with Datawire. FDMS Rapid Connect will provide you with the following values:

The FDMSRegister control must be used to activate the merchant and receive a DatawireId. Once you acquire the DatawireId and receive your transaction URLs through ServiceDiscovery, you may begin to authorize transactions. For instance:

FDMSRegister.FDMSPlatform = FdmsregisterFDMSPlatforms.fpRapidConnect;
FDMSRegister.MerchantNumber = "000000999990";
FDMSRegister.MerchantTerminalNumber = "555555";
FDMSRegister.Config("GroupId=20001"); //Required for Rapid Connect

FDMSRegister.TransactionNumber = "1"; //any unique number will do.
FDMSRegister.URL = "https://stagingsupport.datawire.net/staging_expresso/SRS.do";
FDMSRegister.Register(); 
FDMSRegister.TransactionNumber = FDMSRegister.TransactionNumber + 1;
FDMSRegister.Activate();
FDMSRegister.ServiceDiscovery(FDMSRegister.PrimaryDiscoveryURL);
for (int i = 0; i < FDMSRegister.ServiceProviders.Length; i++) {
  FDMSRegister.Ping(FDMSRegister.ServiceProviders[i]);
  Console.WriteLine(FDMSRegister.ServiceProviders[i] + " = " + FDMSRegister.PingResponseTime);
}

To authorize a credit card set the MerchantId, MerchantTerminalNumber, and GroupId properties with the values supplied by FDMS Rapid Connect. Set the DatawireId property with the value retrieved by the FDMSRegister control after activating your merchant account. Set the URL property with one of the URLs you retrieved during ServiceDiscovery.

Transaction Processing

To being processing transactions first set the required merchant values. For instance:

debit.TPPID = "AAA000";
debit.MerchantTerminalNumber = "00000001";
debit.MerchantId = "1234";
debit.GroupId = "20001";
debit.DatawireId = "00011122233344455566";
debit.ApplicationId = "RAPIDCONNECTVXN";
debit.URL = "https://stg.dw.us.fdcnet.biz/rc";

Next specify transaction specific information. These values uniquely identify the transaction to Datawire and FDMS.

debit.STAN = "112";
debit.TransactionNumber = "1234";
debit.ReferenceNumber = "1212";
debit.OrderNumber = "123";

Then specify customer card and address information along with the transaction amount:

debit.Card.MagneticStripe = "4003010001234572=17041011234567440";
debit.EncryptedPIN = "7BD8948B328B21E5";
debit.KSN = "876543210F008400029";

debit.TransactionAmount = "1200"; //$12.00

Finally, submit the transaction by calling the Sale method.

debit.Sale();

The ResponseCode property indicates the result of the transaction. A code of 000 indicates success. For all other values please see the Response Codes section. Additional Response properties such as ResponseApprovalCode, ResponseAuthorizedAmount, ResponseText, ResponseAVSResult, ResponseCVVResult, and more, provide further details about the transaction response.

To perform subsequent operations on a transaction, such as calling Reverse to reverse a Sale, or calling Capture to capture a previous AuthOnly transaction the GetDetailAggregate method must be used to get details about the original transaction. This aggregate must be stored securely, it will contain cardholder information that is required for subsequent transactions. For instance:

debit.Sale();

//Save the detail aggregate to use with Reverse
string aggregate = debit.GetDetailAggregate();

//The aggregate must then be stored securely.
//At a later time the aggregate is retrieved in order to perform a reversal.

//Reverse
debit = new Fdmsrcdebit();
...

//Specify the detail aggregate from the original transaction
debit.SetDetailAggregate(aggregate);

debit.ReversalTransactionType = FdmsrcdebitReversalTransactionTypes.frttSale;
debit.ReversalType = FdmsrcdebitReversalTypes.fdrtFullReversal;
debit.Reverse();

Transaction Types

In addition to a basic sale transaction, additional transaction types exist for other common operations. Not all transaction types are applicable for all controls. Check the method list for applicable transaction types.


AuthOnly	An authorization that must be Captured later.
BalanceInquiry	Inquire about available balance.
Capture	Captures a previous AuthOnly transaction for settlement.
