It would be awesome if there was a way to see what Checkout Rules are active in a store. Since we can’t programmatically create them to enable our cart validation function, we have to direct store owners to the settings to enable it themselves. It would be nice to first check for the existence of a rule with our function so we could know if they’ve already done it and mark that onboarding step as complete.
Another option would be to allow programmatic rule creation as outlined in this topic:
