2Checkout supports 1-click purchases for returning customers who paid for their previous orders with:

• Credit/Debit cards

How does this work?

1. Identify returning customers.
2. Retrieve the payment method token.
3. Collect the CVV from the customer.
4. Place a new order using a valid payment method token and CVV.

Requirements

• TransientToken required for the placeOrder method. Can be retrieved from getCustomerInformation.
• This method only woks with Credit/Debit cards.
