Refunding orders with multiple shipping lines returns accurate data

Orders with multiple shipping lines may be refunded. You can refund shipping amounts using the refundCreate GraphQL mutation, the returnRefund GraphQL mutation, or the Refunds REST API.

As of July 18, 2024, all Admin GraphQL API versions return accurate refunds data for orders with multiple shipping lines.

1. Shipping refunds will be included in the refundShippingLines connection, in addition to shipping lines removed via an order edit.
2. For each refunded shipping line, there will be an OrderAdjustment with kind SHIPPING_REFUND. Previously, there would be a single OrderAdjustment with kind SHIPPING_REFUND regardless of how many shipping lines were present on the order.
3. The RefundAgreement has multiple shipping line sales. Each ShippingLineSale corresponds to exactly one shipping line that was refunded. The ShippingLineSale.shippingLine is now populated for all API versions for the RETURN action type.

As of July 18, 2024, all REST API versions return accurate refunds data for orders with multiple shipping lines.

1. For each refunded shipping line, there will be an order adjustment with kind = shipping_refund in the order_adjustments property. Previously, there would be a single order adjustment with kind = shipping_refund, regardless of how many shipping lines were present on the order.

Please note that Refund.refundShippingLines and RefundAgreement.sales are only available in the Admin GraphQL API. They are not present in the Admin REST API.
