I am trying to create a custom shipping service for my store. I have followed an article from Shopify and was able to create the shipping service (Custom Shipping Rates) but it can't be used for any shipping zones defined on Shopify. Just gives the below error:
There are no available services for the country you've selected.
Not sure if there are any other API calls required to permit a shipping service to be available in a specific country.
Any help on this will be appreciated!
