Opting-in to Account Updater happens at the organization level - all environments will be affected. By turning on the Account Updater feature, you confirm that all eligible cards will be sent to the card brands for updates twice monthly, but you will only be charged for those cards that are actually updated or flagged. These updates happen automatically by Spreedly in the background and your customers can continue using your service without interruption.Once you opt in, you can select which of your cards will be sent to the card networks for updating. By default, all payment methods are going to be included. The only fields that may be updated are card number and/or expiration date (year/month). All other fields are ignored.
