TSYSDebit Component

Properties   Methods   Events   Config Settings   Errors  

The TSYSDebit 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. Supported Industry Types include retail stores, restaurants, and grocery stores.

Syntax

DPayments.DPaymentsSDK.Tsysdebit

Remarks

This component allows for simple, direct, secure connection to the Vital/TSYS SSL gateway through a standard Internet connection. Because all SSL communications are handled inside the component, any application or web page can be deployed without the need for expensive dedicated SSL servers.

The TSYSDebit component makes authorizing debit card transactions (where the customer's card is swiped through a card reader and a PIN is supplied) very easy by adding an additional layer of abstraction between the programmer and the protocol. There is no need to deal with raw sockets, SSL handshakes, or data packet formatting. The steps to setting up the component and authorizing a transaction are outlined below:

First, set the merchant properties with setup information acquired from your member bank or processor. For instance:

TSYSDebit1.Reset TSYSDebit1.MerchantBankId = "999995" '(BIN Number) TSYSDebit1.MerchantNumber = "888000002447" TSYSDebit1.MerchantName = "TEST MERCHANT" TSYSDebit1.MerchantTerminalNumber = "1515" TSYSDebit1.MerchantStoreNumber = "5999" TSYSDebit1.MerchantCategoryCode = "5999" TSYSDebit1.MerchantCity = "Durham" TSYSDebit1.MerchantState = "NC" TSYSDebit1.MerchantZip = "27713" TSYSDebit1.MerchantTimeZone = "705" TSYSDebit1.MerchantABANumber = "123456789" TSYSDebit1.MerchantSettlementAgent = "V123" TSYSDebit1.AgentBankNumber = "000000" TSYSDebit1.AgentChainNumber = "111111" TSYSDebit1.ReimbursementAttribute = raStandardRetail TSYSDebit1.SharingGroup = "GWQEV5" TSYSDebit1.IndustryType = itRetail

Next, set properties that contain details about the transaction. The TransactionNumber is a sequence number, and should be incremented for each transaction you send. BatchNumber indicates which batch you will settle this authorization in. It should match the BatchNumber you set in the TSYSSettle component when you settle this transaction. TransactionAmount is the amount of sale, plus any CashBackAmount returned to the customer, formatted with an implicit decimal place. The CardTrack2Data is read from the magnetic stripe on the back of the card, and the DebitPIN and DebitKSN are retrieved from a standard DUKPT Pin Pad device.

TSYSDebit1.TransactionNumber = 1 TSYSDebit1.BatchNumber = 213 TSYSDebit1.TransactionAmount = "1000" TSYSDebit1.CashBackAmount = "300" TSYSDebit1.CardTrack2Data = "9999999800002773=09121015432112345678" TSYSDebit1.CardPIN = "83C33384650827F6" TSYSDebit1.CardKSN = "4A00310459400004"

Finally, submit the transaction by calling one of three authorization methods. Sale, Credit or BalanceInquiry. The following code demonstrates a purchase: TSYSDebit1.Sale()

If wish refund money to a customer's debit card, you must also supply an OriginalPurchaseDate before calling Credit.

When the component receives a response from the Vital/TSYS servers, the result of the authorization will be displayed in several Response properties. The Code indicates whether the transaction was approved, and the remaining properties provide additional information about the transaction.

Once a debit card Sale or Credit is approved, the transaction must go through the batch settlement process in order for the merchant to receive the funds in his merchant account. This is done by passing the XML aggregate returned from the GetDetailAggregate method to the TSYSSettle component. Usually, a Batch Settlement of all authorized transactions is done at the end of each business day. Note that BalanceInquiry transactions can not be settled.

Syntax

• C#
• VB.NET

public int BatchNumber { get; set; }

Public Property BatchNumber As Integer

Default Value

1

Remarks

Unlike regular credit card transactions, Debit, EBT, and GiftCard transactions require that the Batch Number be sent in the authorization request. This number should be the same number you set to the TSYSSettle component's BatchNumber property. The range is from 1 to 999.

CardTrack2Data Property (TSYSDebit Component)

Track 2 data for a debit transaction

Syntax

• C#
• VB.NET

public string CardTrack2Data { get; set; }

Default Value

""

Remarks

This is a variable length field with a maximum data length of 37 characters. For Retail Card Present transactions, this property will contain the entire UNALTERED track as read from a credit card's magnetic stripe. This includes all framing characters. However, the track should be converted to 8-bit ASCII before this property is set (most card readers do this automatically).

Industry regulations do not allow merchants or processors to store track data in any form of persistent storage. Failure to abide by this regulation can result in significant fines and other penalties.

CashBackAmount Property (TSYSDebit Component)

Amount returned to the customer in cash.

Syntax

• C#

Remarks

This property may contain an optional cash back amount when authorizing a Debit Purchase transaction, EBT Cash Benefit Purchase, or a Gift Card Purchase transaction. The value of TransactionAmount must reflect the cost of the goods or service purchased plus this CashBackAmount.

Note: CashBackAmount must be empty for Restaurant IndustryType as this is not supported by TSYS.

Note: TSYS does not support transactions containing both CashBack and Gratuity/Tip amounts.

This amount is to be presented with an implied decimal point. For example, US $10.00 must be represented as 1000, and $0.10 is likewise simply 10. The allowable number of significant digits as well as the positioning of any implied decimal point is dictated by the designated CurrencyCode configuration setting. In the United States (default), the number of allowable significant digits is seven. Thus the maximum TransactionAmount is "9999999", yielding a US dollar amount of $99,999.99. This field may not contain a negative number.

Note: For EBT Withdrawal transactions, CashBackAmount must be empty. However, when creating detail records for the settlement of the transaction, the DebitCashBack in the detail record must match the TransactionAmount for the authorization.

Public Certificate(ByVal CertStoreType As CertStoreTypes, ByVal Store As String, ByVal StorePassword As String, ByVal Subject As String, ByVal ConfigurationString As String)

CertStoreType identifies the type of certificate store to use. See StoreType for descriptions of the different certificate stores. Store is a file containing the certificate store. StorePassword is the password used to protect the store. ConfigurationString is a newline separated list of name-value pairs that may be used to modify the default behavior. Possible values include "PersistPFXKey", which shows whether or not the PFX key is persisted after performing operations with the private key. This correlates to the PKCS12_NO_PERSIST_KEY CryptoAPI option. The default value is True (the key is persisted). "Thumbprint" - an MD5, SHA-1, or SHA-256 thumbprint of the certificate to load. When specified, this value is used to select the certificate in the store. This is applicable to cstUser, cstMachine, cstPublicKeyFile, and cstPFXFile store types. "UseInternalSecurityAPI" shows whether the platform (default) or the internal security API is used when performing certificate-related operations. After the store has been successfully opened, the component will attempt to find the certificate identified by Subject . This can be either a complete or a substring match of the X.509 certificate's subject Distinguished Name (DN).
