Before now, gift cards would only apply to the first payment in a Stripe subscription. Now the full gift card balance is redeemed when applied to a subscription on your Stripe payment / checkout links. If a customer applies a gift card that has a higher balance than the first payment of the subscription, the remaining balance is automatically applied as a credit balance to the customer’s record in Stripe. This means all future subscription charges are automatically adjusted till the gift card balance is fully used, after which the payments switch back to the payment method on file. This is automatically enabled and works with no further action needed from you.
In your Stripe account, you will see relevant metadata on the customer and subscription record and this will be shown as a separate line item on the gift card page. Once the credit balance is applied in Stripe, the gift card balance becomes zero immediately. Cardivo automatically handles scenarios where a gift card might be used for a one-off payment first, and then subsequently applied to a subscription.
