Apply these rules to apps using the 2026-01 GraphQL Admin, Storefront, Customer Account, webhook, and Function APIs, and UI extensions configured for 2026-01. This stable line is accessible until 2027-01-16 15:00 UTC. Authentication services, App Bridge, SDK releases, and app distribution and privacy requirements evolve independently of the API quarter. Apply the language and runtime controls appropriate to the app's implementation as well.

Version scope, runtimes, and security fixes

  • Pin Admin calls to /admin/api/2026-01/graphql.json, Storefront calls to /api/2026-01/graphql.json, [webhooks].api_version to 2026-01, and each versioned extension or Function's api_version to 2026-01. Select the Customer Account API's 2026-01 endpoint explicitly; discovery examples can return the latest version.
  • Check X-Shopify-API-Version on API responses and webhook deliveries, monitor API health and deprecations, and upgrade before this line expires. Shopify falls unsupported requests forward to an available version; an HTTP success does not prove the requested schema was used.
  • Use maintained Shopify authentication libraries and keep them on releases that Shopify's advisories list as fixed. Read the JavaScript app-proxy advisory's fixed list yourself rather than waiting for npm audit or Dependabot, which may not report it. For JavaScript apps, check the @shopify/shopify-api copy that npm ls @shopify/shopify-api resolves under the Express, React Router, or Remix package, not only the wrapper's version, because the app-proxy fix changed both; check resolved
