I have a customer that currently has a Shopify website and we want to be able to use a feed from their website to display products within our software and take payments.
The questions I have are below:
Does Shopify allow payments to be managed outside of the website?
Can we use a device such as an IPP350 to make physical payments or does it have to be Shopify hardware and only handle payments within the app?
Can we pull the products via REST and get stock accuracy?
The ideal situation would be the user would be able to add products to the cart and then check-out on a touchscreen and then pay for the products via a physical POS system and send a response back to the website to say that a user has purchased something.
