The Vault API provides a secure way to store customer credit cards. By storing cards with PayPal, you can avoid storing them on your servers.
Support for direct payments with credit cards varies by country.
To store a customer credit card, specify the card details in a call to the Vault API. A card ID is returned. To take a payment with the card, specify the card ID (instead of specifying the credit card details). If you provided a payer ID when you stored the card, include the payer ID when you charge the card.
