A newly created credit card may not have
paymentDueDate available. What value should be supplied for this field?
A suitable default could be chosen.
It would also be valid not to respond with the BankingCreditCardAccount structure, in the event that it is a new card without any balance yet due, and hence there is no
minimum payment or
payment due amount. Setting the account type to
credit card does not make the inclusion of the BankingCreditCardAccount mandatory. This structure should be supplied if it can be validly constructed.
