Hey @user290, this was actually answered in your previous thread - the short answer is that Marketing Automation data isn’t available via any API.
The marketingEvents query you’re using is for tracking campaigns created by marketing apps (like Facebook ads or Mailchimp campaigns), not Shopify’s built-in automations like abandoned checkout recovery.
If you need to track abandoned checkout metrics yourself, you could use the abandoned checkout webhooks to build your own tracking, but the native automation analytics aren’t exposed via the API currently.
