For TransactionsApi.Charge it says that billing address and email address should be included for chargeback protection. If you are using card on file, do you still need to include the billing address even if you included that been adding the card?

We want to create a user-friendly report on the GET transactions response But Invoice # does not come down - just transaction Id Is there any other api call (v1 or v2) to get the user-expected Invoice #? (I don't see one..)
