I ran into this tutorial using every technology in the world which is supposed to show how to build a react app from the ground up to leverage the shopify API. However there also this page describing a simple API call to do more or less what I need.
The goal is to have an entirely custom (extremely simple) checkout process that ends up in the shopify system. It would go something like this:
Stripe purchase ok -> shopify order saved -> thank you page redirect.
EDIT: It appears that the format https://api_key:[email protected]/admin/api/2019-07/orders.json solves the authentication problem. The call:
GET https://key:[email protected]/admin/api/2019-07/orders.json
returns a pleasant
{
"orders": []
} so the authentication is a-ok.
However, doing a POST https://key:[email protected]/admin/api/2019-07/orders.json
Seems to return a cryptic page, instead of an error like so (which simply leads to your demo store/app):
