PayPal - Create Direct Credit Card Payment

See more PayPal Examples

Creates a direct credit card payment where your application passes the credit card, shipping, and payment information to PayPal.

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

Note: This is an example where you handle the card data directly, and therefore you would need to ensure you are PCI compliant. There are other ways to create a payment where your application does NOT handle the credit card data directly.
