How to Test Opsgenie Webhooks

Opsgenie webhooks send alert lifecycle notifications so your systems can automate incident response and escalation.

Opsgenie Official Webhook Docs

1. Opsgenie Webhook Events

Opsgenie can send the following webhook events to your endpoint:

alert.created
alert.acknowledged
alert.closed
alert.escalated
alert.add_note
alert.add_tags

2. Set Up a Test Endpoint with HookRay

Follow these steps to start receiving Opsgenie 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 Opsgenie 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 Opsgenie Webhook Payload

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

payload.json
{
  "action": "Create",
  "alert": {
    "alertId": "12345-67890-abcde",
    "message": "Webhook delivery queue backing up",
    "priority": "P1",
    "source": "hookray-monitoring",
    "tags": [
      "production",
      "critical"
    ],
    "createdAt": 1763587200
  },
  "source": {
    "name": "Datadog Integration",
    "type": "API"
  }
}

4. Common Issues & Troubleshooting

Webhook not arriving?

Check that your endpoint URL is correct and publicly accessible. Opsgenie 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 Opsgenie's side. Check your webhook configuration and event selection.

Need to verify webhook signatures?

Opsgenie 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 Opsgenie-specific fields highlighted automatically
  • Check the Opsgenie webhook documentation for the complete event reference
