Ok Instead of doing all these. (This seems to be complex for me and not good way)
Here is what I am looking for.
I Just need to check which line items have been shipped (how many Quantities) , so that I can update it at my end. I will be running an Azure function here and it will fetch all the updated orders and their line items, Then I need to decide which items are shipped or not.
what could be better option here ?
I also checked there is a field “quantity_shipped” Can I use this one, right now this is giving 0 because shipped some orders using API not through APP?
