hey @humble imp, can I ask you to provide a bit more details? You should almost never use payment_method_data which is more for extremely advanced integration passing raw payment method details information (like raw card details while being PCI compliant)

Normal integrations should collect payment method details client-side with Elements instead

[humble imp]

Agreed - however this is from an ecommerce platform with their own integration

And I think they rely on using payment_method_data for some reason

I'm sorry but I need a lot more context than this, right now this is super abstract and I don't really understand what you are even asking.
But ultimately when you pass payment_method_data we expect you to pass all the payment method details at once. For a card that means card number, CVC and expiration date (which is extremly sensitive and you should never do)

Taking a step back: when you charge a card you are supposed to make sure the billing details are provided when the card was collected, so on "card creation" not later on PaymentIntent confirmation
So I feel like you're mixing things up and misunderstanding what needs to happen, but it's hard to say right now because I don't really get the context of what you are trying to do
