Stores Using Market-Driven Shipping
If your store has moved to Shopify’s market-driven shipping, shipping options are set on each market rather than in shipping profiles. Add ShipMagic to each market you want it in as a carrier-calculated shipping rate, choosing ShipMagic App. After installing, open the Shipping Zones page in the app. If ShipMagic isn’t added in some of your markets, the page lists them. Click a market’s name to open it in Shopify.Add ShipMagic as a Rate Provider (Custom Profiles & Zones)
Go to Shopify Admin → Settings → Shipping and Delivery
Open the custom shipping profile where you want to add ShipMagic
Under your desired shipping zone, click “Add shipping option”

Set the Rate type to “Carrier or app calculated” and select “ShipMagic App” from the dropdown

Ensure “Automatically include new services when they become available” is checked
If you see an error like below after selecting "Carrier or app calculated", then it means that CCS is not enabled for you.
