I'm trying to get the shipping rates from store using API, I tried with CarrierService, but only has the calculated carrier rates, and i want to retrieve the simple shipping rates.
How i can get these shipping rates?
You can use the ShippingZone API - https://help.shopify.com/en/api/reference/store-properties/shippingzone
I know it's an old thread. But it comes up as a top Google search result.
