Google Ads API v25 sunset in August 2027

Google Ads API v25 is sunset in August 2027 (Google gives the month, not the day). After it, every request to it fails with an error. The failure is loud: calls return errors. Google names v26 as the replacement (listed for release in October 2026). Record your real calls on v25 before the date and replay them on v26: after it, nobody can record what v25 returned. Find every place your code pins v25: 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 Aug 2027

How to upgrade

  1. Find every place your code and config pin v25: 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 v25 and v26 in Google's notes, and list the calls that touch it.
  3. Before August 2027, send your real calls to v25 and to v26 and compare the answers: same status, same fields, same values where they should match; after it, nobody can record what v25 returned.
  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 v25 and one at v26 with the same golden, and you see which of your calls answer differently before August 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 Google Ads API v25 and replay them on v26 until August 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.
