I have in my shopify site some orders fulfilled with an email assigned but not a registered account, what I’m trying to do is to create a page with a form where I ask a customer loged-in the order number generated when created the order with its email, so I can assign a relation between the current customer loged-in and the order previously created , I’m looking at this documentation link : https://help.shopify.com/en/manual/orders/edit-orders?utm_campaign=Guru+Ask&utm_medium=Forums&utm_source=social#edit-an-order and found it’s possible to make some modifications manyally if the order is before 60 days of being created, but I couldn’t found more information about assigning a customer with an order.
I just want to know if this is possible using some liquid/html/js tools? or any way for doing it.
Thank you
