Move Shopify Scripts Before the June 30 Shutdown Breaks Checkout Logic

Shopify has confirmed that Shopify Scripts stop executing on June 30, 2026. Confidence level: confirmed. This affects Shopify Plus stores that still use Scripts for line-item discounts, shipping rules, or payment customizations, and the replacement path is Shopify Functions or compatible Functions-based apps.

What changed

Shopify's developer changelog says Scripts can no longer be edited or newly published after April 15, 2026, and all Shopify Scripts cease to execute on June 30, 2026. Shopify says Functions now cover discounts, shipping, and payments, which are the main areas merchants previously customized with Scripts.

The Help Center frames the migration as an action for Shopify Plus stores using Script Editor. Merchants need to review their Scripts customizations report, decide which customizations still matter, and either install compatible Functions-based apps or rebuild the logic using Shopify Functions.

Key takeaways

• June 30, 2026 is the execution cutoff for Shopify Scripts.
• The April 15 editing cutoff has already passed, so existing Scripts are effectively frozen.
• Shopify Functions is the replacement path for discount, shipping, and payment logic.
• Store teams should audit active Scripts before assuming an app or Function covers every edge case.
• The highest-risk stores are Plus shops with promotion logic, wholesale rules, payment hiding, or custom shipping behavior tied to Scripts.

Availability and access

Shopify Functions are available through the Shopify platform and are installed as part of an app. Shopify's Help Center says Functions are configured in the Shopify admin, distributed through apps, and do not require merchants to edit code directly when using an app-based replacement.

For custom builds, developers need a Functions-capable app setup and a tested migration path. Independent migration guides consistently warn that this is not a simple syntax conversion from Ruby Scripts. Scripts and Functions use different runtimes and programming models, so teams should verify behavior with real checkout scenarios before June 30.

Practical LinkLoot angle

This is a platform-risk deadline, not a feature launch to bookmark for later. If a store still depends on Scripts, the useful move is a narrow audit: list every active Script, map each one to a Function or app replacement, test the top revenue paths, and prepare a rollback plan that does not rely on Scripts working after June 30.

Teams using automation can turn the audit into a repeatable checklist: export current customizations, generate test carts, compare discounts and shipping outputs, and flag mismatches for manual review. LinkLoot's AI workflow automation guide is a useful pattern for structuring those checks, but checkout changes still need human approval.

What to verify before you act

• Open the Shopify Scripts customizations report in the store admin and list every active Script.
• Confirm whether each Script maps to a Shopify Function, a public app, or a custom app build.
• Test high-value carts: wholesale, bundles, subscriptions, free shipping, international orders, and payment restrictions.
• Check whether any business rules depend on data that Functions cannot access at runtime.
• Schedule production verification before June 30, because Scripts should not be treated as a fallback after the cutoff.

Last-mile migration check
- Inventory active Scripts and their business owner.
- Match each Script to a Function type or app replacement.
- Test checkout behavior with real promotion and shipping scenarios.
- Deactivate replaced Scripts only after the Function or app has passed parity checks.
- Keep a post-cutoff monitoring plan for checkout, discounts, and payment failures.

Source check

Confirmed by:

• Shopify's developer changelog confirms the April 15, 2026 editing cutoff and the June 30, 2026 execution cutoff.
• Shopify's Help Center confirms that Scripts will be removed, will no longer work, and should be replaced with compatible Shopify Functions for payment, shipping, or line-item use cases.
