Answer 1

You are probably looking for hosted-payments feature of Shopify.

This is where payment gateways can implement their payment processing with Shopify checkout.

You have to create a public page / website where Shopify will redirect after click on "place order" button.

There on this page/website you can have all order details and implement the gateway using curl requests etc.

More info you can find at Hosted Payment SDK where you can see an Api reference for Request and Response values.
