To store a card to be reused later we are using the E-Commerce Create Customer endpoint, which returns the Customer ID that we can use to charge (source field).
We realized that this process apparently only supports one single card on file? Is that correct?
If we update the customer with a new token (a new card), the card on file is updated. but we can still see the list of all cards by using the Customer Developer API. But we couldn't find a way to use these previous cards as a source when we are charging.
Are we limited to pass a "CustomerID" or a "token" in the source field in the Charge Endpoint? How could we use a previous card on file without collecting it again from the customer?
Thanks in advance
