id can be
passed as depositDetails.cardId to Create payment intent
(transactionType: deposit) to top up the wallet without the customer
re-entering card details. This group lets you list and remove those saved cards.

Saving cards is a gated feature: it must be enabled on your merchant account.
If it isn’t, cards are never tokenized and these routes return
403 (“This feature
is not enabled on your merchant account”).
