Authorize Method

Authorizes a Canadian debit card transaction.

Syntax

ptechcanadiandebitcontrol.Authorize

Remarks

This method sends a Canadian (Interac) debit card transaction to the Paymentech Server The transaction sent is based on the InteracTransactionType. Authorize can only be used to send customer-initiated transactions that require that the customer physically enter his PIN on the PIN pad device - meaning Sales, Returns, and Voids. Administrative transactions are handled via the RequestCurrentKeys, ReversalAdvice, and MACReversal methods.

An example sale is shown below:

  control.MerchantNumber = "yourMerchantNumber"  
  control.TerminalNumber = "100"
  control.ClientNumber = "0002"
  control.UserId = "yourUserId"
  control.Password = "yourPassword"
  control.SequenceNumber = 2
  control.TransactionAmount = "1.00" 
  control.PinPadSerialNumber = "30700015P3600000" ' from label on back of PIN pad
  control.InteracTransactionType = ittSale 
  control.AccountType = acctChecking       
  control.CardTrack2Data = "9999999800002773=05121015432112345678" ' from card reader
  control.EncryptedPIN = "FFFFFFFFFFFFFFFF" ' from the PIN pad 

  ' Now use the PIN pad to MAC the value returned from GetRequestDataToMAC 
  ' and then set MACValue with the results
  control.MACValue = "FFFFFFFF"             

  control.Authorize()

If the ResponseCode is "A", load the PIN pad device with the ResponsePINKey and ResponseMACKey, and then validate the ResponseMACValue against the value returned by GetResponseDataToMAC using the PIN pad. If the MAC does not validate, call MACReversal to reverse the transaction.
