    Browsers don’t make cross domain ajax request. It is restricted. You have to use either api or jsonp. Your question is already answered at here.

    You are missing the simplest piece of the PUZZLE. You do not make Ajax Requests to your very own server from a Shopify store without using the App Proxy. If you have installed an App in the store, then you can use the App Proxy. Using the App Proxy, you can securely POST/GET to your endpoint at your domain, without CORS or that shockingly bad JSONP crap.

    TL:DR; all your problems with Ajax disappear when you use the App Proxy.

    I do this “sort of” API calls, not product create just getting info, on a separate app on Heroku. Sinatra works fine.

    Assuming you are using Ruby/Sinatra, do something like this on your Heroku/Whatever App:

        configure do
     $apikey = ENV['API_KEY']
     $password = ENV['PASSWORD']
     $shopname = ENV['SHOPNAME']
    end

post '/somepath' do
  puts params.inspect
  ShopifyAPI::Base.site = "https://#{$apikey}:#{$password}@#
  {$shopname}.myshopify.com/admin"
  my_variant = ShopifyAPI::Variant.find(variant_id)
  puts my_variant.inspect
  #or whatever you want to do
end

    The approach is to construct your base site and then issue calls to the various API like this:

    ShopifyAPI::Product.create(:handle => 'foo', :title => 'Foo')

    You’ll probably need more options, just look at the JSON docs and try and map them to the Ruby API library. You can always of course use raw JSON, but you’ll need to handle the authentication which the shopify_api Ruby gem handles for you:

    Hope this helps.

    You definitely want to avoid CORS/JSONP, they fail behind firewalls for customers, also silently with security add-ons, all sorts of ways. Very frustrating for them. Embedded, Proxy Apps are the way to go if you need to send something from your site via straight up JSON to an external app. All you need to do is create an embedded app, very easy with the Rails Gem and not too hard with the Sinatra one, there is also sample code on the Shopify site, and make it a proxy as well.

    This means when your site submits to mystore.shopify.com/apps/some-path/some-otherpath it proxy passes through to myapp.heroku.com/some-otherpath or wherever your app is hosted.

    But if you just need to touch Shopify to get products and stick them in a database, or modify them, or create them via some outside app, the above code will work for you with obviously some modifications.
