Pause Meta Ad Sets Automatically When a Shopify Product Sells Out
The fastest way to burn ad budget is paying for clicks to a sold-out product. This workflow watches Shopify inventory and, the moment a product hits zero, pauses the exact Meta ad sets promoting it — then re-enables them when stock returns.

Frequently asked questions
How does it know which ad set promotes which product?
You keep a simple SKU to ad-set-id map (a small Google Sheet or a constant in the Code node). The workflow looks up the id when a product sells out. Ten minutes of setup that pays for itself the first time a bestseller runs dry.
Will it fight my ad manager's automated rules?
No — it only pauses on true zero-stock and resumes on restock. Keep your bid and budget rules as they are; this just prevents spend when the product literally cannot be bought.
