# **Intercom Webhook Tester — Test & Inspect Online**

Test and inspect Intercom webhooks online with a free webhook tester URL — capture real Intercom payloads, read the signature header, then forward locally.

![Intercom Webhook Tester](https://webhookrelay.com/blog/intercom-webhook-tester/images/blog/heroes/tester.jpg)

If you are wiring up Intercom webhooks, the first question is always the same: _what does Intercom actually send?_ The docs show an idealised payload, but the real request — its headers, its `X-Hub-Signature` header, the exact JSON shape — is what your handler has to parse. A **Intercom webhook tester** gives you a public URL that captures those real requests so you can read every byte before you write any code.

## [Get a free Intercom webhook tester URL](#get-a-free-intercom-webhook-tester-url)

The fastest way is our free [Webhook Bin](https://webhookrelay.com/blog/intercom-webhook-tester/webhook-bin/) — a no-code [webhook tester](https://webhookrelay.com/blog/intercom-webhook-tester/webhook-bin/) that gives you an instant public URL and stores every request that hits it, headers and body included. No signup, no deploy:

1. Open the [Webhook Bin](https://webhookrelay.com/blog/intercom-webhook-tester/webhook-bin/) and copy the URL it generates for you.
2. In **the Developer Hub → your app → Webhooks**, add a webhook endpoint and paste that URL.
3. Trigger an event (see below) and watch the request land in the bin in real time.

Because the bin keeps the full request, you can inspect the `X-Hub-Signature` header, the `Content-Type`, and the complete payload — the three things you need to build and verify a handler.

## [What a Intercom webhook looks like](#what-a-intercom-webhook-looks-like)

Intercom delivers webhooks as an HTTP POST with a `application/json` body. Intercom wraps every event in a `notification_event` envelope with a `topic` field, and signs with the older `X-Hub-Signature` (SHA-1) scheme — capture one to see the deeply nested `data.item` structure.

A typical `conversation.user.created` payload looks like this:

```
{
  "type": "notification_event",
  "topic": "conversation.user.created",
  "data": {
    "item": {
      "type": "conversation",
      "id": "...",
      "source": {
        "author": {
          "type": "user",
          "email": "jon@example.com"
        }
      }
    }
  }
}
```

Common Intercom events you will want to test:

- `conversation.user.created`
- `conversation.admin.replied`
- `contact.created`

## [Verifying the Intercom signature](#verifying-the-intercom-signature)

Intercom signs each request so you can prove it really came from Intercom. The signature travels in the **`X-Hub-Signature`** header and is HMAC-SHA1 of the raw request body, using your app's client secret. Capture a real request first, then use our [HMAC signature verifier](https://webhookrelay.com/blog/intercom-webhook-tester/hmac-verification/) and the [verify a webhook signature](https://webhookrelay.com/blog/intercom-webhook-tester/blog/verify-webhook-signature/) guide to confirm your verification logic against a payload you can actually see.

## [From inspecting to receiving on localhost](#from-inspecting-to-receiving-on-localhost)

A bin is perfect for _seeing_ the payload. When you are ready to drive your **local** handler with real Intercom events — without deploying — forward them straight to `localhost` with the Webhook Relay agent. The full walkthrough is here: [Receive Intercom webhooks on localhost](https://webhookrelay.com/blog/intercom-webhook-tester/blog/receive-intercom-webhooks-locally/).

That gives you a stable public URL that tunnels to your machine, so Intercom keeps delivering to the same endpoint while you iterate on `localhost`, no firewall changes or public IP required.

## [Test Intercom webhooks online in three steps](#test-intercom-webhooks-online-in-three-steps)

1. **Capture** — point Intercom at a [Webhook Bin](https://webhookrelay.com/blog/intercom-webhook-tester/webhook-bin/) URL and inspect the real request.
2. **Verify** — confirm the `X-Hub-Signature` header with the [HMAC verifier](https://webhookrelay.com/blog/intercom-webhook-tester/hmac-verification/).
3. **Forward** — when the shape is clear, [receive Intercom webhooks on localhost](https://webhookrelay.com/blog/intercom-webhook-tester/blog/receive-intercom-webhooks-locally/) and build your handler.
