Your automation didn't crash.
It just quietly stopped working.

Create a monitor

Tell us how often the workflow should run and how much slack (grace) to allow. You get a unique ping URL.

Ping it at the end of each run

Add one HTTP request as the last step. Optionally POST the run's output so we can check it.

Get alerted when it goes quiet

No ping within period + grace, an explicit /fail, or output that fails your rules triggers an alert by email, Slack, Discord or Telegram. You get one alert per incident, plus a recovery notice.

Schedules that stop

A deactivated scenario, an expired credential, a paused Zap, a server that rebooted without its cron.

Empty or broken AI output

Require non-empty output, valid JSON, specific keys (e.g. summary, items.0.id) or forbid phrases like "I'm sorry" or "error".

Runs that start but never finish

Ping /start at the beginning; if the completion ping doesn't arrive within the grace period, we alert.

n8n — HTTP Request node

Add an HTTP Request node as the last step. To validate AI output, send it as the body.

Method: POST
URL: https://flowhush.com/p/<your-ping-url>
Send Body: on  ·  Body Content Type: JSON
Specify Body: Using JSON
JSON: {{ JSON.stringify($json) }}

On failure: in an Error Trigger workflow (or the node's error output), call https://flowhush.com/p/<your-ping-url>/fail.

Make — HTTP module

Add HTTP → Make a request at the end of the scenario.

URL: https://flowhush.com/p/<your-ping-url>
Method: POST
Body type: Raw  ·  Content type: JSON (application/json)
Request content: {{the output bundle you want checked}}

Add an error-handler route with another HTTP module pointing at https://flowhush.com/p/<your-ping-url>/fail.

Zapier — Webhooks by Zapier

Add a Webhooks by Zapier → POST action as the final step.

URL: https://flowhush.com/p/<your-ping-url>
Payload Type: json
Data: output → (map the field from the previous step)

A GET action with just the URL works too if you only need a heartbeat.

curl / cron / scripts

# heartbeat after a successful run
my-job.sh && curl -fsS -m 10 --retry 3 https://flowhush.com/p/<your-ping-url>

# report start, success or failure explicitly
curl -fsS -m 10 https://flowhush.com/p/<your-ping-url>/start
my-job.sh && curl -fsS -m 10 https://flowhush.com/p/<your-ping-url> \
          || curl -fsS -m 10 https://flowhush.com/p/<your-ping-url>/fail

# send output to be validated (e.g. AI agent JSON)
curl -fsS -m 10 -X POST -H 'Content-Type: application/json' \
     --data-binary @output.json https://flowhush.com/p/<your-ping-url>
