On June 30, 2026, every Shopify Script stops executing. This is the final deadline — it has already been pushed twice (August 2024 → August 2025 → June 2026), and Shopify has stated this one is firm. Editing and publishing new Scripts was already turned off on April 15, 2026.

Most "deadline" posts about this frame it as a migration-project problem: audit your Scripts, rebuild them as Functions, ship before the date. That's true. But it buries the part that actually bites.

Here is the part that makes this dangerous.

When a model gets retired — Imagen, an OpenAI snapshot, a Grok slug — the failure is loud. The call returns an error, your pipeline throws, someone gets paged. Loud failures get fixed.

A Shopify Script ceasing to execute is not loud. There is no Script to call and fail. The checkout simply runs without it. The customer reaches the thank-you page. Shopify returns a completed order. Your logs show a successful checkout. Everything is 200 OK.
