Submitting Credit Card Transactions

Planning Your Gateway Integration

The Payflow SDK also supports the following credit card features:

 Address verification service and card security code validation

 Card-present (SWIPE) transactions

 Partial authorizations for pre-paid cards

 Purchasing card transactions

 Reference transactions (also called tokenization)

 Submitting Soft Merchant information

Planning Your Gateway Integration

When designing your Gateway integration, evaluate:

 Whether to use a one-step or two-step transaction process. One-step: Submit a sale

transaction, which performs the authorization and (if successful) then flags the transaction

for settlement. Two-step: Perform an authorization-only transaction and then later perform

a delayed capture transaction. The delayed capture transaction can be for the same amount

as the original transaction or for a lower amount. (In the case of a split shipment, you can

perform a delayed capture transaction for the initial shipment and a reference transaction

for the final payment.

According to card association rules, most physical goods merchants should use a two-step

process, since settlement should occur when the merchant ships the goods. A two-step

process is also useful for evaluating information in the response, such as whether the issuer

verifies the billing address, and so on. Electronic goods merchants, who fulfill the order

immediately, can use the one-step process. Check with your Internet Merchant Account

provider for suggestions on the best method for you.

 Whether or how to use risk management tools such as address verification service and card

security code. For the address verification service, if the initial transaction submits the data,
