I was using Sage pay integration for my client in M1 site. Recently, client migrated the website to Magento 2 and now in search of the same extension.
Check our Magento 2 Opayo Payments to integrate Sage Pay payment gateway which is now known as Opayo to Magento 2 store.
Currently, our extension offers 2 integration types, Opayo direct and Opayo form payment.
You can use one as per your requirement.
