How to fetch Shopify store orders using Shopify's API

Question

I'm struggling to import the orders for a Shopify development store using the httr package in R. Here's what I've tried.

1. I've created a development store and made some fake orders.
2. Within my development store, I added a private app and generated my API key and Password
3. Following this article, I tried implementing the following request

Code

apikey <- "foo"
pass <- "bar"

shop <- GET(
  url = "my-test-store.myshopify.com/orders.json", 
  authenticate(user = apikey, password = pass)
)

But this gives a 401 status code. However, this works but returns xml instead of json

shop <- GET(
  url = "my-test-store.myshopify.com/orders", 
  authenticate(user = apikey, password = pass)
)

How can I retrieve the results as JSON instead of XML?

Note that I can also fetch the orders using the R package shopifyr but would rather not use that package as it is no longer maintained.

Update 2019-05-13

I created an R package called shopr for querying data via the Shopify API. Fetching orders looks like this

library(shopr)

shopr_get_orders(
  shopURL = "https://my-test-store.myshopify.com", 
  APIKey = "abc123", 
  APIPassword = "def456"
)

Figured it out.

orders <- GET(
  url = "https://my-test-store.myshopify.com/admin/orders",
  add_headers(Accept = "application/json"),
  authenticate(user = apikey, password = pass)
)
orders

The trick was to explicitly put "https://..." in the url otherwise httr was prepending "http://" to the url, causing my 401 problem.
