Opayo Suite and Hyvä Checkout Compatibility
At the moment our module is compatible with the three different Hyvä checkouts found HERE, in different ways.
Hyvä Checkout
The Hyvä Checkout, featuring the best Hyvä Theme integration and customizability, available as a separate product.
Fully compatible with an extra module, you can find it at our store https://store.ebizmarts.com/ebizmarts-payment-suite-for-hyva-checkout-m2.html
You can find more information on how to install this HERE.
Luma Checkout
The Luma Checkout, which includes a module that allows falling back to a different theme on specific pages.
As a better alternative to the default Magento Luma checkout, consider OneStepCheckout, which also can be used with the fallback module.
Fully compatible without the needs of any extra module.
Hyvä React Checkout
The React Checkout, an open source community supported checkout for developer teams with React JS experience. This enables you to use the standard Magento checkout with any standard Magento checkout extension.
Compatibility with PI Integration, with and without DropIn, more information on how to set in the links below:
