To sync new signups to Shopify:
1 - Navigate to a campaign in your Privy dashboard. On the campaign’s Automation settings (all the way at the right), click the "+ New Rule” button and choose which account and list you want to sync new signups to.
Then click save.
2 - Select your Shopify account, and ensure that the “Customers” list is selected and click Create sync.
3 - That’s it! New signups will be synced to Shopify as Customers who accept marketing. Please refer to the Invite customers to create accounts article in the Shopify Help Center if you would like to create accounts for Shopify Customers synced from Privy.
