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.

Set up a webhook See pricing

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 (the exact format is in the API reference under Webhook signatures).

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 X-SiteGauge-Timestamp header value, a dot, and the raw request body using that secret. The X-SiteGauge-Signature header carries the result as sha256= followed by the hex digest, so compare against that.
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 works the same way: point the channel at an n8n Webhook node, or subscribe that node through our REST-hook API with an API key.
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.
