Hi! I would like to add a custom attribute to each line item in an order that can be populated at the time of fulfillment. For example, I offer personalized videos as products, and I would like to add the link to the video once it has been created. The customer can purchase multiple personalized videos, so I need to add a unique link to each line item. Any suggestions on how to accomplish this?
In case you're unfamiliar with these technologies you'll likely need to hire a Shopify developer to assist you.
If you wish you can e-mail me, this is something I do fairly often for my clients.
You'll probably want to use something like this: https://apps.shopify.com/custom-fields-2
