In https://www.marqeta.com/docs/core-api/3ds#_receive_an_advanced_authentication_challenge, we need to create an endpoint "/three-ds/decision" on our server so Marqeta can POST to it.
The docs say:
Marqeta-assigned unique card token identifying the user.
36 char max
card_token is Optional - in what cases is this field null? We hope there's always going to be a "card_token" when Marqeta POSTs to that endpoint - it means someone is swiping their card and that we need to determine if we want to push them through the 3DS authentication flow. So how can this be null?

By optional of course that doesn't only mean null, but also that the field isn't in the request body - in what cases is that possible?
