Hosted Payment Page hand-off from Hikashop

-- url of the page with the problem -- : ngaanyatjarraku.wa.gov.au
-- HikaShop version -- : 4.5.1
-- Joomla version -- : 3.10.9
-- PHP version -- : 7.4.29
-- Browser(s) name and version -- : Firefox 100.0.2

We have been advised that In order to comply with the latest PCI DSS (Payment Card Industry Data Security Standard), we need to hand credit card payments off to a bank hosted payment page rather than using the currently implemented HikaShop credit card payment plugin. Could someone please provide instructions on how to achieve this so that the HikaShop still completes and records the sales. A confirmation of payment will be sent to the shop administrator by the bank's payment page, but of course HikaShop still needs to send the order to the administrator and a confirmation to the customer. Can that be achieved with the paid version of HikaShop?

Your help would be much appreciated!

Thank you for the prompt reply, Nicolas. We use Westpac Bank and their payment system is called PayWay Net. It gives me the option to implement a "A PayWay hosted web page" (their preferred option), or a "A PayWay iframe embedded into your payment page". I found the "westpacapi" plugin in the Payment methods of HikaShop, but Westpac told me that would not satisfy the PCI DSS compliance. I can not find a plugin which would forward the payment to this external site while maintaining the normal HikaShop functionality.
Any suggestions, Nicolas?

Hi Nicolas,
I installed the Westpac NET plugin. That was the easy part - the setup on the Westpac page was much more painful! But I have finally got it working.
Thank you very much for your help!
Best regards,
Jimmy
