Hi @bjornbennett

I used your code.
But its show an error
Access to XMLHttpRequest at 'https://shop.test.co.nz/cart.json' from origin 'https://testDomain.nz' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource.

Hmm not sure why you're getting an error for cart.json, although the code sends an AJAX request to cart.js. Are you sending an AJAX request to cart.json instead? Typo maybe? I just tried it again on the link above and it appears to still be functional.
