How to Test PagerDuty Webhooks

PagerDuty webhooks (v3) deliver incident lifecycle events so your tools can track when incidents trigger, acknowledge, and resolve.

PagerDuty Official Webhook Docs

1. PagerDuty Webhook Events

PagerDuty can send the following webhook events to your endpoint:

incident.triggered
incident.acknowledged
incident.resolved
incident.escalated
incident.reassigned
incident.priority_updated

2. Set Up a Test Endpoint with HookRay

Follow these steps to start receiving PagerDuty webhooks for testing:

  1. Go to HookRay and click "Start Testing — Free" to get your unique webhook URL.
  2. Copy the URL (e.g., https://h.hookray.com/abc123).
  3. In your PagerDuty dashboard, navigate to the webhook settings and paste the HookRay URL as your endpoint.
  4. Select the events you want to receive (see list above).
  5. Trigger a test event — HookRay will show the incoming webhook in real-time.

3. Sample PagerDuty Webhook Payload

Here's an example of what a PagerDuty webhook payload looks like:

payload.json
{
  "event": {
    "event_type": "incident.triggered",
    "resource_type": "incident",
    "occurred_at": "2026-03-20T13:30:00.000Z",
    "data": {
      "id": "P56789X",
      "title": "High error rate on webhook ingestion",
      "status": "triggered",
      "urgency": "high",
      "service": {
        "name": "hookray-api"
      }
    }
  }
}

4. Common Issues & Troubleshooting

Webhook not arriving?

Check that your endpoint URL is correct and publicly accessible. PagerDuty cannot reach localhost URLs — use HookRay's cloud URL instead.

Getting 400 or 500 errors?

HookRay accepts any payload and returns 200 OK by default, so the issue is likely on PagerDuty's side. Check your webhook configuration and event selection.

Need to verify webhook signatures?

PagerDuty signs webhook requests for security. Use HookRay to capture the raw headers and body, then implement signature verification in your application code.

5. Next Steps

  • Use HookRay's webhook replay feature to re-send captured webhooks while building your handler
  • Enable smart parsing (Pro plan) to see PagerDuty-specific fields highlighted automatically
  • Check the PagerDuty webhook documentation for the complete event reference
