Creating a Shopify Order via postman / Shopify API

Question

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:api_secret.@my-store.myshopify.com/admin/api/2019-07/orders.json solves the authentication problem. The call:

GET https://key:secret@my-test-store.myshopify.com/admin/api/2019-07/orders.json returns a pleasant { "orders": [] } so the authentication is a-ok.

However, doing a POST https://key:secret@my-test-store.myshopify.com/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):

So, in summary, I have a store, an authorized app (which successfully authenticates) so how do I add an order for an existing SKU programmatically?

Answer 1

Are you sure there are no cookies on the request? Because I can reproduce your exact issue if I add cookies.

It might be easier to use curl in order to have absolute clarity into what is being posted. For example:

# Edit to change app hostname, key/secret, and product/variant/customer ids 

curl -X POST 'https://key:secret@so57018447.myshopify.com/admin/api/2019-07/orders.json' \
-H 'Content-Type: application/json' \
-d '{
  "order": {
    "line_items": [
      {
        "product_id": 2017449607219,
        "variant_id": 17985741619251,
        "quantity": 1
      }
    ],
    "customer": {
      "id": 1257159000115
    },
    "financial_status": "pending"
  }
}
'

Response:

{
  "order": {
    "id":952834392115,
    "email":"",
    "closed_at":null,
    "created_at":"2019-07-15T14:38:18-04:00",
...

But if you want to stick with Postman, here are the supporting screenshots showing success without cookies, and failure with:

Confirming there are no cookies set:

Successful post to orders.json endpoint:

Now, add a cookie:

And I get the response shown in your question:
