How to Test Intercom Webhooks

Intercom webhooks notify your app about conversation events, user actions, and lead activity so support and sales workflows stay responsive.

Intercom Official Webhook Docs

1. Intercom Webhook Events

Intercom can send the following webhook events to your endpoint:

conversation.created
conversation.user.replied
conversation.admin.replied
conversation.closed
user.created
user.tag.created
contact.created
contact.signed_up

2. Set Up a Test Endpoint with HookRay

Follow these steps to start receiving Intercom 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 Intercom 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 Intercom Webhook Payload

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

payload.json
{
  "type": "notification_event",
  "topic": "conversation.user.replied",
  "data": {
    "type": "conversation",
    "item": {
      "id": "conv_abc123",
      "state": "open",
      "user": {
        "id": "usr_456",
        "email": "customer@example.com"
      },
      "conversation_message": {
        "body": "I need help testing my webhook endpoint."
      }
    }
  }
}

4. Common Issues & Troubleshooting

Webhook not arriving?

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

Need to verify webhook signatures?

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