MobilePay Online – Change UI Option

As parts of the PCI-DSS best practice becomes requirements with PCI-DSS v4 coming in April 2025, using the Seamless View integration to display the payment UI will give merchants more responsibilities than they currently have. This is because Seamless View is hosted by you. As the Redirect integration is hosted by Swedbank Pay, we also handle these responsibilities.

The updated requirements will include stricter controls and monitoring, particularly around the security of your checkout process. A script or other monitoring needs to be in place to verify that the checkout URL is correct and has not been tampered with. This is to avoid phishing or hijacking, and to secure that the URL provided is from us at Swedbank Pay.

See points 6.4.3 and 11.6.1 in the PCI-DSS link above for more.

To learn more about how PCI-DSS affects you, we also have reading available in Danish, Finnish, Norwegian and Swedish.

If you currently have a Seamless View integration and don’t want the impending responsibilities, switcing to Redirect is a very manageable task. While you can make the change and keep on using your payment method integration(s), we strongly recommend switching to Digital Payments when you are already making changes to your integration.

If you choose to continue using payment method integrations, here’s what you need to do:

Use Redirect Operation

In the operations node of the payment response, right next to view-authorization which you should currently be using, you’ll find redirect-authorization. The corresponding href contains a url which leads to a Swedbank Pay domain where the payment UI will be displayed and processed. All you need to do is direct the Payer to this url and wait until one of the functions are called (completeUrl, cancelUrl or callbackUrl) to proceed with the payment process.

          "rel": "redirect-authorization"
          "contentType": "text/html"
        },
    ]
}

Remove Seamless View Code

You can remove all code related to the <script> element used to load the Seamless View.

Change URLs

Finally, you need to do some changes to the urls node in your payment request. The paymentUrl field is specific to Seamless View and can be removed.

The url you need to add is the cancelUrl, so we know where to redirect the payer if they chose to cancel, or you chose to abort the payment.

If you have permission to add your own logo in the payment UI and want to add one, you also need to include a logoUrl. Follow the guidelines in the section linked above. If no logoUrl is added, Swedbank Pay’s logo will be shown by default.

The completeUrl, hostUrls and callbackUrl is universal and must be included regardless of your UI choice.
