Any idea why
https://apiverson.ordoro.com/order/<order_id> shows the carrier_name as
null when it was shipped using usps/ups/fedex?
For the v3 Orders API We use
carrier_name for manual trackings only. If you shipped an order with a shipper, the shipper id can be used to retrieve additional information about the shipper. See api documentation for GET shipper/shipper_id.
This API is currently in flux and we will likely update the shipping_info response shape as time goes on.
