How to get LineItem details for an UnverifiedReturnLine

GraphQL Admin API Troubleshooting
1

May I please have confirmation of the points below by anyone who’s run into similar requirements?

  1. I’ve noted from other forum posts that the way to get an Order’s original LineItem details for a Return is to go through the FulfillmentLineItems. I.e. If I have an order with multiple items, one of which is ‘Blue T-Shirt’ which gets returned, I’d essentially go (pardon my simplified object) Order.Return.ReturnLineItem.FulfillmentLineItem.LineItem to get things like the Order’s Line Item Id, the SKU, etc.
    Can anyone confirm this?

  2. An Unverified Return seems to create a new Order with new lines which represent the items being returned. However, in an Unverified Return, the customer always gets a gift card. So if I return two items in an Unverified Return, the resulting new Order has three LineItems - the two products and a gift card, and two UnverifiedReturnLineItems. How do I match the two product Order LineItems to the two UnverifiedReturnLineItems?
    One possible solution seems to be to use the Customer Account API, which has a LineItem object (see UnverifiedReturnLineItem - Customer API) going through Customer.Orders.Returns…etc.
    Can anyone confirm that this is the way to go?
    I would like to avoid a solution whereby I just match the two lists of lines based on their ordering.

Thanks in advance!
