Monitoring n8n and Zapier AI workflows

Updated 5 November 2026.

Workflow tools retry and log, but they don't tell you when a scheduled workflow quietly stopped running, or when the AI step "succeeded" with an empty or useless answer.

n8n

• Add an HTTP Request node as the last step of the workflow: method GET (or POST with a short summary as the body), URL https://cronpup.com/p/YOUR-UUID.
• Put an IF node before it that checks the AI step's output is non-empty; route the empty branch to an HTTP Request to https://cronpup.com/p/YOUR-UUID/fail.
• In an Error Trigger workflow, request /fail so failed executions alert immediately.

Zapier

• If your plan includes Webhooks by Zapier, add a GET or POST action to https://cronpup.com/p/YOUR-UUID as the last step of the Zap.
• Use a Filter or Paths step so the ping only happens when the AI step produced a usable result.

Pick the schedule

For a scheduled trigger use a cron monitor with the same schedule and time zone; for event-driven workflows that should run at least every N hours, use a period monitor of N hours. More on the AI agents use-case page. Start free.
