There should be something wrong with the code on this document, the variables don’t correspond.
Can a friend help me look at it? Thank you, sir.
Hey @Martin11231
As I know, this feature is available for Shopify plus plan.
So please check if your store is plus, or you may consider using a shopify public app to achieve a so complex function.
Hope this helps
