Webhook Notifications

Webhook notifications let you send change alerts to external services. Site Spy supports 90+ notification services through Apprise, including Discord, Slack, Microsoft Teams, and custom HTTP endpoints.

​

Setting up webhooks

1. Go to the Notifications page in the dashboard
2. In the Webhook Notifications section, paste a webhook URL
3. Click Add

You can add multiple webhook URLs. Each one receives notifications when any of your watches detect a change.

​

Testing webhooks

After adding a URL, click Test next to it. A test notification is sent immediately so you can verify the connection works.

​

Supported services

Webhook URLs use Apprise syntax. Some common examples: See the full list of 90+ supported services.

​

Per-watch overrides

By default, webhooks apply to all your watches. You can also set notification URLs on individual watches through the API, which override the global webhooks for that watch.

​

Removing webhooks

Click Remove next to any webhook URL to delete it. The change takes effect immediately.

​

Dead webhooks are switched off automatically

If a destination fails permanently — the Discord webhook was deleted, the endpoint returns 401, 404, or 410 — Site Spy disables that URL after 5 consecutive permanent failures and emails you. Temporary failures and timeouts do not count; they are retried. Re-add the URL once the destination works again.
