Hi,

I try this code, but i don't get results. It's still functional in the last updates of Shopify?

Can you tell me more about how can i implement it?

Thank you

I would look into - https://shopify.dev/api/ajax/reference/cart#post-cart-clear-js this method above was always a hack prior to this clear cart js ability being added

Hi Bmodena,

This is fantastic. Question, can you modify this to have a different trigger? For example, rather than having the user trigger the cart being cleared when logging out, can we use a time frame? Example logic statement: 15 days after the cart was created, the cart clears.

Thanks!

I think by default the Shopify cart expires in 14 days. As far as I know It is not possible to get the expiration date of a cookie through Javascript. So you would have to look into https://shopify.dev/api/ajax/reference/cart GET /cart.js endpoint and it looks like this has a few "created_at": "2019-04-10T20:49:00.148Z", values in the response. If those are tied to cart creation time you could use that.
