Customer Experience

  • Merchants can provide a checkbox in their payment flow to let customers choose to save their card.
  • If checked, pass the customerId when creating the payment intent (create a new customer if needed, then use their customerId).
  • On the first successful payment with a customerId, the card is saved to the customer’s profile.
  • On future purchases, customers will see their saved cards as payment options at xPay checkout. (You have to send the customerId in the create-intent request to get the saved cards)
  • Customers can select a saved card to pay instantly, without re-entering card details.
  • Customers can also manage (delete or use another saved card) from the xPay checkout during any transaction.
