Paypal Express V2

The PayPal Express V2 integration, provides an accelerated checkout process that enhances user experience. By allowing customers to quickly complete transactions using their PayPal accounts, this integration reduces cart abandonment and speeds up the payment process. With streamlined authentication and approval steps, PayPal Express V2 ensures a secure, efficient, and user-friendly checkout for your e-commerce platform. Next to your standart checkout you also have the possibility to use the Javascript SDK to render the PayPal buttons and react to certain PayPal events. 

Express vs Standart

We offer the freedom to implement the payment options on several pages:

on the product page
Your customers can directly pay on your product page.

on the shopping cart page
Your customers can chose to pay on your shopping cart page

Regular on the checkout page

as a regular checkout on the payment solution page.

The PayPal Express V2 handles the first two cases, Product page and Shopping Cart page. For more information about the Regular Checkout please use our PayPal V2 implementation guide. 

Javascript SDK and API Requests

There are two possibilities to render the PayPal button. The merchant can use a dynamic PayPal button, or use the standart PayPal javascript SDK to render the buttons and also react to some key responses (onApprove, onError, onCancel, on ShippingChange).

The JavaScript Button Render offers a straightforward and efficient means to integrate a the PayPal button into your website, enhancing both functionality and user experience. For all information about the Javascript SDK please see our Implementaiton guide and the PayPal Javascript SDK page.

Before proceeding to specific API requests for PayPal V2 your should familiarise yourself with the general Payone Server API interface definition as described in Channel Server API - Platform - PAYONE docs.
In this section we will describe the request chain specific remarks for PayPal Checkout V2 integration.

PayPal Express Integrations

POST Request - genericpayment – add_paydata[action] = setexpresscheckout

For PayPal Express V2, the request type 'genericpayment' is mandatory. The first 'genericpayment' request will generate a workorder ID from the PAYONE platform, which will be included in the response. This ID is unique and is required for all subsequent requests related to PayPal Express Checkout.

Process Description:

  • First of all you have to use the request “genericpayment”
  • The parameter “add_paydata[action]=setexpresscheckout” and add_paydata[payment_action]=CAPTURE or AUTHORIZE
  • With “setexpresscheckout” you initiate the transaction at PayPal and get an unique “workorderid” from the PAYONE platform
  • After the successful request you do another “genericpayment” request with “add_paydata[action]=getexpresscheckout details” to get the shipping and email address of the customer
  • To charge the customers PayPal account you have to do a request “preauthorization/capture” or an “authorization” with the unique “workorderid”
  • After completing step 4 you will get the “txid” which is used for further steps like “capture”, “debit” or “refund”

It is mandatory to provide the shipping address in the 'authorization' or 'preauthorization' request if it differs from the shipping address received in the 'genericpayment[action]=getexpresscheckoutdetails' response. Failing to do so will result in the loss of PayPal seller protection. The 'genericpayment[action]=getexpresscheckoutdetails' call returns only the customer’s shipping address from PayPal. Additionally, use the shipping address as the billing address. Customers should be given the option to change the billing address during checkout. If you wish to enable multi-partial capture, you must set 'settleaccount' to 'yes' or 'auto' in order to allow for subsequent captures. Do not set 'settleaccount' to 'no'.
