In-depth guide

Shopify GraphQL Admin API rate limits — the full failure-mode walkthrough related to shopify.dev, checked against official docs, with linked verified routes.

Steps

  1. Confirm current status at shopify.dev/docs/storefronts/themes/architecture/layouts/checkout-liquid: checkout.liquid is already unsupported for the Information, Shipping, and Payment steps
  2. Plan migration of any remaining checkout.liquid usage on the Thank-you and Order-status pages (including additional scripts/script tags) before the August 28, 2025 sunset
  3. Separately track Shopify Scripts, which continue working alongside Checkout Extensions only until June 30, 2026 — do not assume it shares the checkout.liquid deadline
  4. Rebuild custom checkout logic using Shopify's app-extension framework ("Checkout Extensibility"), documented at shopify.dev/docs/apps/build/checkout/technologies
  5. Confirm whether checkout.liquid access is currently enabled for your store, since it is Plus-only and must be explicitly toggled via Shopify support
