Order Editing API supports discounts on fulfilled line items

You can now apply discounts to line items that have already been fulfilled using the order editing API, resulting in more flexible order adjustments. The orderEditAddLineItemDiscount mutation now supports discount application to both fulfilled and unfulfilled line items.

What this means for you:

• Clearer transaction history: Discounts on fulfilled items improve post-purchase financial attribution and reporting.
• Simplified order management:Orders automatically unarchive when you begin editing and re-archive after issuing refunds, eliminating the need for manual archive management.
