Can’t get Shopify cart via jsonp crossdomain anymore about shopify-code-snippets HOT 3 OPEN

Interesting. It's possible that JSONP is no longer accepted but would have to look into it.
Do you have some replication steps/code used so I can give it a test using the same process?

To test I'm running your script in the console. I get the response from shopify, it's just without any items which I can see are in the cart when I visit the shop.

This could be far fetched, but I think I've figured it out. It looks like it works when I have https setup and only when i'm running the script from the same main domain. So it works when I run it on a subdomain of the main shopify store. But cross-domain with a totally different domain doesn't look like it works anymore. Could be related to chrome setting same-site: lax as default on cookies or some other cookie restriction shopify has limiting the session to only be available on the main domain.

Edit: I can confirm that it get the correct cart when request is made from a subdomain of the same main Shopify domain and over ssl. To test locally i suggest running your local server over https (adding certificates was a pain) and adding a testing subdomain.maindomain to your hosts file.

Looks like @oscarni is correct about the cookies. My shop is on a subdomain, so I'm able to set my own cookie that is usable by both domains.
