The TSYSHCECommerce component is used to authorize credit cards in both Mail Order (Direct Marketing) and eCommerce environments, where the customer is ordering products or services via the telephone or Internet. This component makes authorizing these types of transactions very easy.

Syntax

TSYSHCECommerce

Remarks

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

The TSYSHCECommerce control makes authorizing Card-Not-Present Mail Order and E-Commerce 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 control 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:

  TSYSHCECommerce1.GenKey = "gen_key_value"
  TSYSHCECommerce1.MerchantId = "merchant_id"
  TSYSHCECommerce1.RoutingId = "routing_id"

Then, set the customer's credit card information, as well as his address and zip code (the address and zip code will be checked by the Vital/TSYS servers to make sure it matches the customer's billing address).

  TSYSHCECommerce1.CardNumber = "4444333322221111"
  TSYSHCECommerce1.CardExpMonth = 1
  TSYSHCECommerce1.CardExpYear = 2013
  TSYSHCECommerce1.CardCVVData = "999"
  TSYSHCECommerce1.CustomerAddress = "8320 South Hardy Dr."
  TSYSHCECommerce1.CustomerZip = "85284"  

Next, set properties that contain details about the transaction. At the minimum, you must set a TransactionAmount and TransactionNumber. However, you may also set the TransactionType if you are doing a Mail Order or Recurring transaction.

  TSYSHCECommerce1.TransactionNumber = 1
  TSYSHCECommerce1.TransactionAmount = "100"
  TSYSHCECommerce1.TransactionType = ttECommerce

Finally, submit the transaction by calling one of four authorization methods. Sale, Credit, AuthenticateCard or BalanceInquiry. The following code demonstrates a purchase:

  TSYSHCECommerce1.Sale()

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

Once a credit card Sale or Credit is approved and 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 control.

Note: The TSYSHCECommerce control can be used to pass 3D-Secure authentication data in an authorization to achieve a better interchange rate. To send this data, the ECI, XID, and CAVV configuration variables must be set before calling Sale. The CAVV authentication result code will be returned in the ResponseCAVV configuration setting.
