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
Availability
Select 2Checkout accounts. Contact 2Checkout for more details.
How does this work?
- Identify returning customers.
- Access data on the previous purchases of returning customers.
- Validate previous order references for 1-click purchase scenarios using the isValidOrderReference method.
- Place a new order using a valid previous order reference as the payment method.
- 2Checkout charges returning customers using their payment-on-file information, either a card or their PayPal account.
Requirements
- Use only references of 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. Note: You need to provide only the email address of the shopper, and can ignore the rest of the required customer billing information. If you enter any billing details in addition to the email address, you'll have to provide all information required in the BillingDetails object.
- For orders paid with PayPal, the original order must have automatic renewal enabled so that it can be reused for future 1-click purchases.
