Token billing

Token billing allows you to store a credit card with your gateway, and charge it at a later date. Token billing is not supported by all gateways. For supported gateways, the following methods are available:

• createCard($options) - returns a response object which includes a cardReference, which can be used for future transactions
• updateCard($options) - update a stored card, not all gateways support this method
• deleteCard($options) - remove a stored card, not all gateways support this method

Once you have a cardReference, you can use it instead of the card parameter when creating a charge:

$gateway->purchase(['amount' => '10.00', 'cardReference' => 'abc']);
