PTechReversal Component

Properties   Methods   Events   Configuration Settings   Errors  

The PTECHREVERSAL component is used to reverse a transaction that was previously authorized with the Paymentech NetConnect system on the Tampa platform. This immediately releases the funds in the cardholder's open-to-buy that were blocked by the original authorization.

Syntax

nsoftware.InPayDirect.Ptechreversal

Remarks

Setting up the component and reversing a transaction is easy. First, set the MerchantNumber, TerminalNumber, ClientNumber, UserId, and Password with the information given to you when you signed up for Paymentech service. You should also set your IndustryType and PINCapability at this time.

After the merchant information is setup, enter the data from the transaction you wish to reverse. Note that the transaction must be a currently open authorization, and cannot have already been settled via the PTechManualSettle component. To reverse an authorization, set the CardNumber, CardExpMonth, CardExpYear, IndustryType, and POSRetrievalNumber which were sent in the original transaction. Also indicate the type of the original authorization (Auth-only or Sale) in the OriginalTransactionType property. The OriginalTransactionAmount should be set to the amount originally sent in the TransactionAmount property of the component that authorized the transaction. It does not matter if the amount actually authorized was less, the originally submitted amount must be sent in the OriginalTransactionAmount property.

For example:

component.IndustryType = itRetail
component.CardNumber = "4444333322221111"
component.CardExpMonth = 1
component.CardExpYear = 2010
component.OriginalTransactionType = ttAuthOnly
component.OriginalTransactionAmount = "1.00"
component.POSRetrievalNumber = "1234567890"
component.Reverse()

The result of the reversal request will be stored in the Response property. The Code field will contain the status of the request and the Text field will contain the human-readable response message. The contents of the Response should be logged after a successful transaction.

Reversal transactions must NOT be added to the batch settlement, and the authorization which was reversed by this component MUST be removed from the batch. Settling a reversed transaction will result in transfer of funds from the customer's credit card to your merchant account, so care must be taken to ensure that reversed transaction are not included in the manual settlement.
