Meta Graph API v23.0 expiry on 8 October 2027

Meta Graph API v23.0 expires on 8 October 2027. After it, calls fall forward to the next oldest usable version, with no error; and every change made since v23.0 applies to calls written for it. The failure is silent: calls still succeed, answered by another version, and no error says so. Meta names v26.0 as the replacement (the latest Graph API version on 8 October 2026, released 29 July 2026). Record your real calls on v23.0 before the date and replay them on v26.0: after it, another version answers in v23.0's place. Find every place your code pins v23.0: 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 8 Oct 2027

How to upgrade

  1. Find every place your code and config pin v23.0: 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.
  2. Read what changed between v23.0 and v26.0 in Meta's notes, and list the calls that touch it.
  3. Before 8 October 2027, send your real calls to v23.0 and to v26.0 and compare the answers: same status, same fields, same values where they should match; after it, another version answers in v23.0's place.
  4. 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 v23.0 and one at v26.0 with the same golden, and you see which of your calls answer differently before 8 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 Meta Graph API v23.0 and replay them on v26.0 until 8 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.
