Test PagerDuty webhooks
PagerDuty sends webhooks for incident events such as triggered, acknowledged, escalated, and resolved, plus service created, updated, and deleted events. Capture them on a free webhooks.cc endpoint to see exactly what PagerDuty sends, then replay deliveries or forward them to your local handler.

How to test PagerDuty webhooks
- 1
Create a webhook endpoint
Sign in free with GitHub, Google, or email to create a persistent endpoint — or grab an instant guest URL at webhooks.cc without an account.
- 2
Point PagerDuty at your URL
Paste the endpoint URL into PagerDuty: Integrations → Generic Webhooks (v3) → New Webhook, or the REST API (POST /webhook_subscriptions).
- 3
Inspect what arrives
Each delivery appears live in the dashboard with method, headers, body, query parameters, and source IP.
- 4
Forward to localhost or assert in CI
Run whk tunnel <port> to forward webhooks to a local server, or use the TypeScript SDK to wait for and assert on deliveries in tests.
PagerDuty webhook authentication
| Auth header | x-pagerduty-signature |
|---|---|
| Algorithm | HMAC-SHA256 |
| Verification in webhooks.cc | Capture deliveries to inspect raw signature material |
The value is v1={hex}, an HMAC of the raw body keyed with the secret PagerDuty returns when the subscription is created. During secret rotation the header carries several comma-separated v1 signatures; accept a match on any.
