The TSYSHCReversal component is used to reverse a previously authorized transaction. This component makes reversing transactions very easy.

nsoftware.InPayDirect.Tsyshcreversal

Remarks

This component allows for simple, direct, secure connection to the Vital/TSYS TLS/SSL gateway through a standard Internet connection. This component can be integrated into web pages or stand-alone Point Of Sale applications. Because all TLS/SSL communications are handled inside the component, any application or web page can be deployed without the need for expensive dedicated TLS/SSL servers.

The TSYSHCReversal component makes reversing transactions 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 component and authorizing a transaction are outlined below:

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

  TSYSHCReversal1.GenKey = "gen_key_value"
  TSYSHCReversal1.MerchantId = "merchant_id"
  TSYSHCReversal1.RoutingId = "routing_id"

Next, set properties that contain details about the transaction. At a minimum, you must set a RetrievalNumber, TransactionAmount, and TransactionType.

  TSYSHCReversal1.TransactionType = ttCreditAuthorizationReversal
  TSYSHCReversal1.TransactionAmount = TSYSHCRetail1.TransactionAmount
  TSYSHCReversal1.RetrievalNumber = TSYSHCRetail1.Response.RetrievalNumber

Finally, submit the transaction reversal request by calling Reverse.

  TSYSHCReversal1.Reverse()

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 reversal was approved. The remaining properties provide additional information about the transaction.

Once a reversal is approved, it is added to the current batch. 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 automatically via a Scheduled Close Batch event that you have setup on your Host Capture Terminal Profile. Alternatively you can manually close a batch by using the TSYSHCBatchMgr component.
