Map shipping methods directly from the order page
When an order is created by an integration (like Shopify), there is typically a shipping method chosen that is not directly recognized by fulfillment services. The chosen shipping method is typically something customer friendly like "Free fast shipping". In order to ensure that this method is passed correctly to the fulfillment service and reduce the risk of orders getting stuck or receiving extra processing charges from your fulfillment service, you can now map the received shipping method to an official method that the fulfillment service can use.
Free fast shipping → UPS Ground
This has been possible for some time through the data mapper tool (in integration settings) but is now possible directly inside an order while choosing a shipping method for an unmapped service.
