PTechRetail Component

Properties   Methods   Events   Configuration Settings   Errors  

The PTECHRETAIL component is used to authorize face-to-face credit card transactions with the Paymentech NetConnect system on the Tampa platform. This component creates a simple interface for processing transactions in the Retail and Restaurant environments. It allows for simple, direct, secure communication to the Paymentech 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.

Remarks

Setting up the component and authorizing 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, you may enter transaction data. When the Credit Card's EntryDataSource is Manually Entered, the merchant should fill the Number, ExpMonth, and ExpYear fields. Address Verification Service (AVS) data may be sent in card-present retail transactions by filling the CustomerAddress and CustomerZip properties. For any other EntryDataSource , the MagneticStripe field should be filled. In addition, the TransactionAmount should be set with the total amount for the transaction, including any taxes.

Now simply call the Sale or AuthOnly method to send the authorization to the Paymentech Server.

The result of the authorization 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.

Once an authorization request is approved, one of three things happen. If you are using the Host Capture SettlementMode, and your Paymentech account is setup with the Host Auto Close feature, you need take no further action. The host will close the current open batch at a designated time each day. This means that there is no end of day batch processing required from the merchant. In order for the merchant's batch to be included in the Paymentech Host Auto Close process, the merchant parameter file on the host must indicate that the merchant is Auto Close. Without this flag being set, the merchant's transactions must be settled with a Manual Batch Release.

If you are using the Host Capture SettlementMode, and your Paymentech account not setup with Host Auto Close, then after an authorization is approved the transaction is added to the current batch on the Paymentech Server, and the money in the customer's account is blocked and tagged for the merchant. The transaction must go through the Manual Batch Release Settlement process in order for the blocked money to be transferred to the merchant's account. To release a batch for settlement, please see the PTechHostSettle component.

If you are using the Terminal Capture SettlementMode, you must store the XML aggregate returned from the GetDetailAggregate method and submit it at the end of the day in a manual batch settlement. A detail aggregate for each authorized transaction must be sent in a batch using the PTechManualSettle component. A transaction that has been authorized and then subsequently voided with this component must NOT be added to the batch settlement, and must not be submitted with the PTechManualSettle component. Any transaction not submitted with PTechManualSettle will eventually time out, and the block on the customer's card will be removed (essentially, you may void transactions by simply not sending them in the batch settlement). The Terminal Capture SettlementMode is required for the Restaurant and Hotel IndustryTypes. This is because both IndustryTypes will generally have additional charges added on to the original authorization (for example: a tip for your server, or a drink from the hotel bar charged to your room). Other IndustryTypes may benefit from this functionality as well, but if you do not require your transactions to be authorized for one amount and then settled for a different amount, it is highly recommended you use the much simpler Host Capture SettlementMode.

Note that a transaction authorized in the Host Capture SettlementMode MUST be released for settlement using the PTechHostSettle component. It cannot be added to a manual batch settlement using the PTechManualSettle component. Doing so will result in charging the customer twice! Likewise, transactions authorized with SettlementMode set to Terminal Capture cannot be released using the PTechHostSettle component, because no record of the transaction has been stored on the Paymentech Server.

Also note that you cannot mix Host Capture and Terminal Capture SettlementModes on the same MerchantNumber / TerminalNumber pair. Contact Paymentech to setup your merchant account for Terminal Capture.
