Your website payment pages must comply with PCI DSS v4.x, which is designed to stop attackers from obtaining cardholder data when processing it in your e-commerce system.

You can meet these requirements in several ways.

Use traditional means, including implementing a Content Security Policy (CSP), using a hash for Sub-resource Integrity (SRI) (now available for the COPYandPAY checkout), and using change detection scans.
Configure monitoring within your content delivery networks (CDNs).
Contract third-party solutions to manage JavaScript security.

Changes to COPYandPAY checkout for PCI DSS 4.x

Add a Content Security Policy (CSP) for the payment page and use change detection scans.

Add the Sub-resource Integrity (SRI) hash every time you create a checkout with the COPYandPAY integration.

Add the new parameter of integrity=true when you create a checkout
There is a change to the create checkout response, which now includes the integrity hash

{
  "result":{
    "code":"000.200.100",
    "description":"successfully created checkout"
  },
  "buildNumber":"d7f3057c29b9a26d5151336767387bb393720d7e@2024-10-14 09:16:49 +0000",
  "timestamp":"2024-10-15 15:16:31+0000",
  "ndc":"FB76D9A1B7D1CAC70A03923F903F74FB.uat01-vm-tx03",
  "id":"FB76D9A1B7D1CAC70A03923F903F74FB.uat01-vm-tx03",
  "integrity":"sha384-/j1gGQsS/nAgGp9u7LjRlD7nwA3h+yXS5aEP/vbzrbpgPWuRDhCuFok3J8lWVC3X"
}

Change to the checkout script
- Replace {integrity} with the value of integrity
- For the crossorigin, replace anonymous with the URL of the website that loads the COPYandPAY checkout

<script 
	src="https://eu-test.oppwa.com/v1/paymentWidgets.js?checkoutId={checkoutId}"
	integrity="{integrity}"
	crossorigin="anonymous">
</script>
