The Shopify api allows you to set a weight default in the store admin. That default (eg. lb) is then used to set minimum weight and maximum weight for shipping rates in the Shipping Section. Using the Shopify Shipping_zone api endpoint, I can get the minimum weight and maximum weight, but I cannot get the unit. Furthermore, the API Shop endpoint also does not include any reference to units. This is very problematic for us as developers. Is there any workaround?
