Severity-based branching
A Switch node on the severity field: critical alerts page the on-call phone, warnings post to chat, and everything is appended to a Postgres or Airtable incident log.
Send NorthDuty Alerts to n8n Workflows
n8n's Webhook node accepts JSON from any source — and NorthDuty's custom webhook channel posts structured alert JSON to any URL. Point a channel at your n8n instance, self-hosted or cloud, and every monitoring signal — downtime, failed journeys, visual changes, SSL expiry — becomes a workflow trigger with the full alert data attached.
Start your 7-day trial — no credit card, free plan after.
Pipe alert JSON into self-hosted n8n workflows - the automation stack agencies own.
What teams automate with NorthDuty + n8n
One Webhook node in, any of n8n's nodes out.
Agency client routing
Branch on project name or base URL so each client's alerts reach that client's channel, ticket queue, or maintenance-report sheet — one workflow for the whole roster.
Auto-remediation hooks
Because n8n can call anything over HTTP or SSH, a specific failure can trigger a runbook: clear a cache, restart a service, or redeploy — then re-check before waking a human.
Own-your-data incident history
Write every alert to your own database and build Grafana or Metabase dashboards on top — no third-party analytics required.
Why n8n users monitor with NorthDuty
Teams that self-host n8n like owning their automation: no per-task pricing, full control over data, workflows in version control. NorthDuty fits the same philosophy from the monitoring side — it watches sites from the outside with nothing installed on them, and hands automation-ready JSON to whatever you run.
In n8n, the alert payload lands as regular workflow data: an IF or Switch node branches on severity or rule type, and from there any of n8n's hundreds of nodes take over — tickets, databases, chat, SMS, or an HTTP request to your own systems. The payload includes the alert title, rule type and label, severity, project id, name and base URL, threshold and observed value with unit and comparator, a dashboard link, and a readable message.
Why this fits the self-hosted stack
External monitoring plus self-hosted automation, each doing what it is best at.
- Works with self-hosted n8n and n8n Cloud alike
- Full alert JSON in the workflow — branch on severity, rule, or project
- Covers every alert rule: health, response time, journeys, visual diffs, SSL and domain expiry, API monitors
- Chain into any n8n node — tickets, databases, chat, SMS, HTTP, SSH
- Monitoring stays external and unbiased: NorthDuty checks from outside your infrastructure, so it still alerts when that infrastructure is the problem
How to connect NorthDuty to n8n
A Webhook node is the whole integration.
1
Add a Webhook node in n8n
Create a workflow with a Webhook trigger node, set the method to POST, and copy the production webhook URL (use the test URL first if you want to inspect a sample).
2
Add a custom webhook channel in NorthDuty
In your NorthDuty project's notification channels, add a Custom Webhook channel and paste the n8n webhook URL as the destination.
3
Route alert rules to the channel
Point the rules you want automated — journey failures, downtime, visual changes, SSL expiry — at the new channel.
4
Branch and act
Trigger a test alert, inspect the JSON in n8n, then add IF or Switch nodes on severity or rule and connect the action nodes you need. Activate the workflow.

View For AgenciesFrequently Asked Questions
Answers to common questions about this monitoring feature and when teams should use it.
Is there a NorthDuty community node for n8n?
A dedicated n8n community node is on the roadmap. Today the standard Webhook node covers the trigger side completely — it receives the full alert payload with nothing to install.
Does this work with self-hosted n8n?
Yes — that is the most common setup. The only requirement is that NorthDuty's servers can reach your n8n webhook URL over HTTPS. n8n Cloud works the same way.
What data does the webhook deliver?
JSON with the alert title, rule and ruleLabel, severity, project (id, name, baseUrl), threshold, observedValue, unit, comparator, dashboardUrl, and a plain-language message.
Which NorthDuty plan do I need?
Custom webhook channels are available on any paid plan; email alerts are on every plan including Free.
