Performing Direct Payment Credit
Card Transactions
This chapter provides guidelines on how to implement PayPal Direct Payment transactions.
Direct Payment offers you credit card payment processing capability through PayPal directly
from the buyer’s credit card.
NOTE: Direct Payment is not a standalone feature. You must use Direct Payment together
with PayPal Express Checkout. See Chapter 7, “PayPal Button Placement and
Page Designs,” for guidelines on how to display the PayPal mark logo with credit
card logos.
With the exception of a few optional PayPal Express Checkout transaction parameters not
covered here, this chapter describes all required Website Payments Pro Payflow Edition
request parameters. Differences exist in PayPal Express Checkout transactions, however, and
these are explained in Chapter 6, “PayPal Express Checkout Transaction Processing.”
