One click (1-click) purchase

Overview 

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

• Credit/Debit cards
• PayPal
• iDEAL
• Alipay
• UnionPay

How does this work? 

1. Identify returning customers. 
2. Access data on the previous purchases of returning customers.
3. Validate previous order references for 1-click purchase scenarios using the isValidOrderReference method (explained below).
4. Place a new order using a valid previous order reference as the payment method. 
5. 2Checkout charges returning customers using their payment-on-file information, either a card or their PayPal account. 

Requirements 

• Use only references to previous orders with one of the following statuses AUTHRECEIVED or COMPLETE.
• The email address of the BillingDetails object is mandatory and it needs to match the email address used as a part of the billing details of the initial order whose reference you're now using to place a new order. 2Checkout checks whether the email addresses are identical, and throws an error if they're not, blocking the order placement process.
