PayPal’s Payflow Pro lets you accept international payments with PayPal. This integration requires a PayPal Payflow Pro account, and you may be required to have a separate merchant account in order to process credit card transactions.
People who complete your form are redirected to an integrated Wufoo payment form to enter their billing information. Wufoo does not store any of this information. It's passed securely to PayPal and they return if the transaction was successful or not.
