Send website change alerts to your own endpoint
Wire SiteGauge into anything that speaks HTTP. Every alert arrives as a signed JSON POST you can verify, so your internal tools, scripts and dashboards react to page changes in real time.
Available from the Standard plan ($24/mo).
How to set it up
The same steps you will see in the product, so there are no surprises.
1
In SiteGauge, open Alerts, click Add channel and pick Webhook (the button below lands you on that exact form).
2
Enter the URL on your own server that should receive the alerts.
3
We POST JSON to it; reply with any 2xx status to acknowledge.
4
After you add it, SiteGauge shows a signing secret once. Store it, then verify the X-SiteGauge-Signature header on each request.
What arrives in Webhooks
- A plain-English AI summary of what changed and why it matters, once analysis completes
- Category and importance score, usually included so the loud signals surface first
- A link back to the full before and after in SiteGauge
- Grouped delivery on your alert cadence, so a busy page never floods the channel
Webhooks FAQs
How do I verify a request really came from SiteGauge?
Each webhook channel gets a signing secret, shown once when you add it. Compute an HMAC SHA-256 of the timestamp, a dot, and the raw request body using that secret, and compare the result to the X-SiteGauge-Signature header.
Which plan do I need for webhooks?
The webhook channel starts on the Standard plan, alongside Slack, Teams, Discord and Telegram. The Free plan sends alerts by email.
Can I use webhooks with Home Assistant or n8n?
Yes. Anything that accepts an HTTP POST works, which is how teams wire SiteGauge into Home Assistant. n8n users can also connect with the SiteGauge community node using an API key instead.
How is this different from the Zapier integration?
Webhooks POST alerts to a URL you control and you write the receiving code. Zapier connects through SiteGauge's REST-hook API with an API key (using Webhooks by Zapier), so you get change triggers into thousands of apps without writing any code.
