Hi guys. I’m struggling. I’m trying to pass some extra specific information to each item stored in the cart object, whenever a customer clicks “add-to-cart”. I know the way is to use line_item.properties. The only problem is, the properties in this case is something that the customer doesn’t have to touch or see. I don’t need to include forms and all. All I want to do is to tell Shopify to do its usual thing and just pass one property to each item, which is going to be computed differently for each customer. What is the most painless way to do it?
I know I could write a form, make the properties private, hide the form and all, but really all of that just to pass one property whenever a customer clicks on the add-to-cart button?
