Currency support

Parameters

Parameters Type/Description

sessionID

Required (string)

 

Session identifier, the output of the Login method. Include sessionID into all your requests. 2Checkout throws an exception if the values are incorrect.  The sessionID expires in 10 minutes.

Order

Required (Object)

 

Object designed to collect all data necessary for an order, including billing, product/subscription plan and payment details.

To place an order with PayPal rather than PayPal Express, use PAYPAL as the type of the PaymentDetails object and send the shopper email and a return URL as part of the PaymentMethod object. See the code sample. 

Workflow

  1. Create the order object. To place an order with PayPal rather than PayPal Express, use PAYPAL as the type of the PaymentDetails object and send the shopper email a return URL as part of the PaymentMethod object. Place the order.
  2. Once you place the order, 2Checkout logs it into the system. At this point in time, the status of the order is PENDING. 2Checkout responds with the Order information object.
  3. Redirect shoppers to the RedirectURL from the Order information object you receive as response from 2Checkout.
  4. Once shoppers log in to their PayPal account and complete the transaction, they're redirected to the ReturnURL you set in the order object. 2Checkout also authorizes the order and updates the status to AUTHRECEIVED. 
  5. If shoppers log in to their PayPal account and fail to complete the transaction or they cancel it, they're redirected to the CancelURL you set in the order object. 2Checkout updates the status to PENDING.

Response

Parameters Type/Description

Order information

  Object containing order information.
