I'm using Braintree hosted fields to allow credit card payments, and users can use multiple cards.
How can I allow users to edit existing cards? For example, when a card is renewed by the bank, it keeps the same card number, but the expiration date and CVV change. I want users to be able to edit the expiration date and CVV to keep the card active. Is this possible, or does the user have to enter in a new card from scratch with the same card number?
Full disclosure: I work at Braintree. If you have any further questions, feel free to contact support
Once your customer has their payment method stored in a Vault record you can use their associated payment method token to run a PaymentMethod.update() call. Using the payment method update you can change most attributes of the stored method, and you can find a full list of those attributes here. When updating actual card information, such as CC number, expiration date, etc. it is recommended that you generate a nonce with the new information rather than entering it manually, but either will work just fine.
