POS Checkout update affecting shipping lines
POS checkout infrastructure has been updated and as a result, there is a change to the display of shipping methods for POS orders. "Retail - no shipping required" will now be displayed as a shipping method for POS orders. Previously, a shipping line was not assigned to POS orders.
This change may potentially require workflow updates for shops who have integrations that rely on the presence or absence of a shipping line, or those who use shipping line information as input for other systems. For example: if you are using a third-party fulfillment integration that automatically fulfills orders based on the presence of a shipping line, your workflow should be updated so that automatic fulfillment does not happen if the shipping line is "Retail - no shipping required".
If your shop has an integration that may use the shipping line, please reach out to your third-party provider to discuss possible workflow changes.
Contact Shopify Support if you have additional questions about this change or require additional help.
