In n8n: **Settings \u2192 n8n API \u2192 Create an API key**.\n2. On **Get workflows**, create a *Header Auth* credential:\n - Name: `X-N8N-API-KEY`\n - Value: your API key\n Reuse the same credential on **Get executions**.\n3. In **Configuration**, set `baseUrl` to your n8n address (no trailing slash) and `staleHours` to how long silence is still normal.\n4. Attach your own alert node after **Find silent workflows**.\n\n### The catch\nThis workflow lives inside the instance it watches. If that instance is down, restarting, or its\nschedule triggers did not re-register, this check does not run either \u2014 and its silence looks\nexactly like everything being fine.\n\nThat is the one failure it cannot cover.
