What you get
Build any integration on top of webhooks.
Webhooks are the universal integration primitive. Whether you're routing alerts into a homegrown incident tool, creating Jira tickets, or feeding a Datadog event stream, the webhook endpoint is where Site Qwality hands off to your systems.
HMAC-SHA256 signatures
Every delivery includes an X-SiteQwality-Signature header so your receiver can verify the payload is genuine and untampered.
Automatic retries with backoff
Failed deliveries are retried with exponential backoff — up to five attempts over 30 minutes — before the delivery is marked failed.
Customisable payload fields
Choose which fields appear in the payload, add custom metadata, or filter events by severity so your receiver only handles what it needs.
Delivery log and inspector
Every webhook delivery is logged with the request headers, payload, response code, and latency — inspect and replay any event from the dashboard.
Multiple endpoints per monitor
Send the same event to multiple endpoints — route one alert to a PagerDuty webhook and a custom audit log service simultaneously.

Retries so you never
Retries so you never
miss an event.
If your endpoint is down or returns a non-2xx response, Site Qwality retries with exponential backoff — 10s, 30s, 2m, 8m, 30m. Every attempt is logged with the HTTP status so you can see exactly what happened.
- Up to five delivery attempts with exponential backoff
- Every attempt logged with status code and response body
- Replay any past delivery from the dashboard or API

Every field your
integration needs.
The webhook payload includes the monitor ID, name, URL, check type, current status, triggered-at timestamp, affected regions, HTTP status code or error, response time, and a link to the incident — enough to create a ticket or route an on-call page with no follow-up API calls.
- Monitor metadata, status, regions and error in one payload
- ISO-8601 timestamps and consistent field names across events
- Custom key-value metadata you define per monitor

FAQ
Questions, answered.
Every delivery includes an X-SiteQwality-Signature header containing an HMAC-SHA256 hash of the raw request body, signed with your webhook secret. Recompute the hash on your side and compare to verify authenticity.
By default, webhooks fire on monitor.down and monitor.recover. You can also enable monitor.degraded, incident.created, incident.resolved, and SSL or domain expiry events.
Site Qwality retries with exponential backoff at 10s, 30s, 2m, 8m, and 30m intervals. After five failed attempts, the delivery is marked failed and logged. You can replay it manually from the delivery log.
Yes. The webhook delivery log in the dashboard shows every attempt with the full payload, headers, response code, and latency. Any delivery can be replayed with one click or via the API.
Yes — webhooks are included on every plan, including the free tier. There is no limit on the number of endpoints or deliveries on paid plans.
