(Chilkat2-Python) PayPal - Create Stored Credit Card Payment

Creates a credit card payment using a card ID from a previously stored credit card (where the credit card was stored in PayPal's vault).

Note: For sandbox calls, you can use the credit card numbers provided in your sandbox test accounts.

Note: This example requires Chilkat v9.5.0.65 or greater.
