On my Shopify Plus store I need tight control over what goes live. A product must not be published unless the following fields are filled out: the main Product Description, the Price, and the key Attribute specifics we maintain in metafields. The rule set is category–aware. For every item in the Electronics collection these checks should run automatically; other categories can continue to publish as they do today. If a merchant tries to save or publish an Electronics product that is missing any of those values, the system should block the action and return a clear error message in the admin. I am open to whichever method works best on Plus—Admin API validation, Shopify Flow, sectioned theme scripts, or a lightweight custom app—so long as the logic lives in the backend and can be maintained easily by our team. Deliverables • Working enforcement logic deployed to our Plus store • A short walkthrough (text or Loom) showing how the rule was implemented and how to adjust categories or fields later • Test proof: one Electronics product that fails with missing data and one that publishes successfully after completion
