First, I tell you to go to Klaviyo, integrations, Shopify, and uncheck Sync to Shopify email subscribers to Klaviyo so list assignment is controlled by Shopify Flow. Then import a provided Shopify Flow file, update the DE and EN list IDs, and add your Klaviyo private API key in the run code. Finally, activate the workflow. Action needed, import the flow, swap the two list IDs, add the API key, and then publish.
