Show and update Shopify Cart on a separate website to Shopify

[Mit99mh]

Is it possible to display the Shopify Cart - and also update the Cart contents - on a separate site not just the Shopify site. E.g. mysite.com is not a Shopify site but contains Products. I can add these products to my Shopify site Cart and also display the contents of the Shopify Cart on mysite.com. I hope this makes sense and any help massively appreciated 🙂

Hi Charlotte and thanks for replying. Does my request make sense? I want to show and update the Cart / Cart contents on a site "outside" Shopify. I understand Shopify has the Storefront APIs but any help is much appreciated as I'm very new to Shopify 🙂
