Card data in a checkout session can also be used to create a stored payment
method that can be used again later. This can be done either at the time of creating a transaction by
setting the store property to true,
or when creating a new payment method
directly from the checkout session.
This deletes the security_code from the
vault and any transaction created later requires the code to be
requested again.
3-D Secure can be used in conjunction with Secure Fields using the hosted 3DS solution. To enable hosted 3DS, add a redirect_url to the API call to create a transaction, and then redirect the buyer to the approval_url in the response.
That’s it for the quick start guide. It’s recommended to look into some of the additional options, theming, adding logos,
and how to work with stored cards.
