How to check if a card is already stored in Paypal Vault
<p>I have managed to integrate the Paypal Vault through their API to store credit card information, retrieve the information and delete a card.
But I am looking for a way to check if the card is already stored in the vault before I store it, but could find any information on how to achieve this.</p>

<p>Any suggestions would be greatly appreciated! TIA!</p>
