You need to create product groups in order to set up your rates.
A product can be added to only one group at a time. You cannot add the same product to several groups.
Requirements
The Carrier Service API is required when using Zapiet - Product Rates, in order to show the rates in the checkout. You can learn more in our Shopify Carrier API guide.
All non-digital products need to be marked as a physical product in Shopify.
Every product group needs to contain a unique set of products.
