Outgoing Webhooks
Free on every plan, and fully customisable - pipe monitor alerts into your own tooling.
Outgoing webhooks let Kawze fire an HTTP request to an endpoint of your choice the moment a monitor goes down or recovers, so alerts can flow into PagerDuty, an internal dashboard, or any tool with a webhook endpoint - not just email or SMS. Webhooks are free on every plan, including Free, with no limit on how customisable they are.
How it works
- Add a webhook to any monitor with a label, the HTTP method (GET, POST, PUT or PATCH), and your target URL.
- Add any custom headers your endpoint needs, such as an auth token.
- Customise the JSON payload using template variables like {{monitorId}}, {{monitorName}}, {{status}}, {{reason}}, {{alertUrl}}, {{dashboardUrl}} and {{timestamp}}.
- Kawze fires the webhook automatically whenever the monitor changes state, alongside any email or SMS alerts you have set up.
Why it matters
- Free on every plan - no tier gates webhook access or the number of webhooks you can add.
- Fully customisable payload and headers, so it can slot into whatever you already use to route alerts.
- Route alerts into PagerDuty or your own tooling today - direct Slack integration is coming soon.
- Runs alongside email and SMS alerting, it does not replace them.
Frequently asked questions
Do outgoing webhooks cost extra?
No - webhooks are free on every plan, including Free, with no limit tied to your tier.
What can I customise in a webhook?
The HTTP method, target URL, custom headers, and the JSON payload itself, which supports template variables like {{monitorId}}, {{monitorName}}, {{status}}, {{reason}}, {{alertUrl}}, {{dashboardUrl}} and {{timestamp}}.
Can I use webhooks to send alerts to Slack?
Direct Slack integration is coming soon. In the meantime, a webhook can be pointed at any endpoint that accepts one, including Slack-compatible incoming webhook URLs or a router like PagerDuty.
Do webhooks replace email or SMS alerts?
No - webhooks run alongside your existing email and SMS alerting, they are an additional way to route the same alert.
This capability lives on Kawze's http monitor - see that page for the full feature list and pricing for that uptime monitor type.
