Payment Data Transfer
Payment Data Transfer (PDT) provides merchants with the ability to display transaction
details to buyers who are redirected back to their site upon payment completion.
NOTE: You must enable Auto Return for Website Payments to use Payment Data Transfer.
Auto Return brings your buyers back to your website immediately after payment
completion. Auto Return applies to PayPal Website Payments, including Buy Now,
Donations, Subscriptions, and Shopping Cart. For more information about Auto
Return, see the PayPal Website Payments Standard Integration Guide.
