Shopify Storefront API 2026-10 unsupported on 16 October 2027

Shopify Storefront API 2026-10 becomes unsupported on 16 October 2027 at 15:00 UTC. After it, requests fall forward to the oldest supported version, with no error; fields and types removed since then stop coming back; and public apps still calling unsupported resources are delisted from the App Store. The failure is silent: calls still succeed, answered by another version, and no error says so. Shopify names 2027-01 as the replacement (a release candidate on 8 October 2026, released as stable on 1 January 2027). Record your real calls on 2026-10 before the date and replay them on 2027-01: after it, another version answers in 2026-10's place. Find every place your code pins 2026-10: npx --allow-git=root github:agentwares/api-sunset scan

$ npx --allow-git=root github:agentwares/api-sunset scan

npx --allow-git=root github:agentwares/api-sunset scan lists every API version your code and config pin (Shopify, Meta Graph, Google Ads, HubSpot, Stripe and the rest of this list) with its end date, what breaks and this page's link. It needs no account and no API key, reads your files on your machine and sends nothing; its one request fetches this data. Free and MIT licensed.

What breaks after 16 Oct 2027

If your app targets an inaccessible version, Shopify falls forward and responds using the oldest accessible stable version. The X-Shopify-API-Version response header names the version that answered; it is the only sign. source
Deprecated fields or types are removed in a subsequent release, so the newer version that answers in its place may no longer have fields your code reads. source
If your app continues to use unsupported resources after the upgrade deadline, it's delisted from the Shopify App Store: users are blocked from installing it for at least seven days and see warnings in the Shopify admin. source

The Storefront API takes the version in its URL: /api/<version>/graphql.json; Hydrogen and the Storefront API client set it as storefrontApiVersion or apiVersion.

How to upgrade

Find every place your code and config pin 2026-10: npx --allow-git=root github:agentwares/api-sunset scan prints each file and line, and the variable name for a .env file, never its value.
Read what changed between 2026-10 and 2027-01 in Shopify's notes, and list the calls that touch it.
Before 16 October 2027, send your real calls to 2026-10 and to 2027-01 and compare the answers: same status, same fields, same values where they should match; after it, another version answers in 2026-10's place.
Change the version string, deploy, and watch the first day's responses.

Record your real calls on the old version before the date, and replay them on the new one.

agentcheck runs scheduled checks of an endpoint. A check sends the request you define (a path or a full URL, a method and a body, with your API key as a header, stored encrypted) on a schedule and compares each response with a golden: exact text, contains, a regular expression or a JSON Schema, none of which costs an LLM call. When a response stops matching, it opens an incident and alerts you. Point one check at 2026-10 and one at 2027-01 with the same golden, and you see which of your calls answer differently before 16 October 2027.

Free: 1 monitored target, hourly checks, badge and public status page. Starter: 3 targets, 5-minute checks, Slack and Discord alerts, 30-day history. Recording the calls your code already makes is a different path: the trace import (POST /api/v1/targets/{id}/traces, or the agentcheck_record MCP tool) takes agent traces, a prompt and an answer, and turns them into checks judged by the LLM judge (Pro). It does not take raw HTTP requests and responses, so for an API the scheduled checks are the way in today.

Migration watch is not built. It would record the calls your code makes to Shopify Storefront API 2026-10 and replay them on 2027-01 until 16 October 2027, with nothing to set up, and email you what answers differently. If you would pay for that, say so with one click. The click is counted; nothing else is sent or stored.
