Introducing Direct Payment
Direct Payment lets your customers who do not have a PayPal account pay using their credit
cards without leaving your website. PayPal then processes the payment in the background.
Direct Payment has a single API operation: DoDirectPayment, which allows you to process
a credit card transaction. This API operation also alerts you to potentially fraudulent
transactions by providing you with industry-standard AVS and CVV2 responses for each
transaction.
NOTE: Transactions processed using the DoDirectPayment API operation are not covered
by the PayPal Seller Protection Policy.
Direct Payment Implementation
When customers choose to pay with a credit card, they enter their card number and other
information on your website. After they confirm their order and click Pay, you complete the
order in the background by invoking the DoDirectPayment API operation. Customers never
leave your site. Although PayPal processes the order, customers aren’t aware of PayPal’s
involvement; PayPal will not even appear on the customer’s credit card statement for the
transaction.The following diagram shows a typical Direct Payment flow:
The numbers in the diagram correspond to the following implementation steps:
1. On your checkout pages, you need to collect the following information from your customer
to be used in the DoDirectPayment request:
– Amount of the transaction
– Credit card type
– Credit card number
– Credit card expiration date
