Hello!

I’m working on integrating Shopify stores with my system using the GraphQL Admin API. My goal is to calculate the shipping cost and delivery estimate values.

Is there a recommended way to do this using GraphQL Admin API, or is this only possible with the Storefront API or via checkout workflows?

Any official guidance, endpoint suggestions, or workaround approaches would be very helpful.

Thank you in advance!
