PayPal Express Checkout Payment Gateway

Last Updated: 20 Dec 2017

The current version of the PayPal Express Checkout Payment Gateway asset in Squiz Matrix is using the NVP/SOAP Express Checkout API that has been deprecated by PayPal. Please use a different payment gateway such as Braintree, PayPal Payment, or PayPal Payflow Pro. Development to support the new PayPal Express Checkout API method is currently in progress but not yet available in Squiz Matrix.

The PayPal Express Checkout Payment Gateway allows you to create a payment solution for your customers, utilising PayPal's express checkout payment options. Please note that in order to use the PayPal Express Checkout Payment Gateway, you will need a PayPal Business or Premier account, capable of accepting payments via express checkout.

Please note that the PayPal Express Checkout online payment gateway posts payment information directly to a remote server. Squiz Matrix does not personally handle any of the sensitive information managed by this payment gateway and is thus exempt from PCI compliance standards.

Once you have added a PayPal Express Checkout Payment Gateway, you can configure its settings on its associated asset screens. The majority of these screens are the same or similar to those for a Standard Page and are described in the Asset Screens manual. In this chapter, we will describe the Details and Display Formatting screens, which are different for a PayPal Express Checkout Payment Gateway.
