# Webhooks

## Webhooks

Webhooks let you receive real-time HTTP notifications when events happen in our store — like a product coming back in stock, a price drop, or an order being shipped. They're ideal for developers, businesses with custom integrations, or anyone who wants to automate workflows based on store events.

### How webhooks work

When an event you've subscribed to occurs, we send an HTTP POST request to the URL you've configured. Your server receives the event data as a JSON payload and can act on it however you like — update a dashboard, trigger a Slack message, sync inventory, or anything else.

### Setting up a webhook

1. Log in to your account and go to [Notifications](/account/notifications).
2. In the Webhooks section, click **"Add Webhook"**.
3. Enter your webhook URL (must be HTTPS in production).
4. Select the events you want to receive.
5. Optionally scope the webhook to a specific product or collection.
6. Click "Create" — your webhook secret will be shown once. Save it securely.

### Available events

- **Back in stock** — A previously out-of-stock product has new inventory.
- **Price drop** — A product's price has decreased.
- **New product** — A new product has been published to the store.
- **New in collection** — A product has been added to a collection you're watching.
- **Order confirmed** — One of your orders has been confirmed.
- **Order shipped** — One of your orders has been shipped with tracking info.

### Payload format

All webhook payloads are sent as JSON with a `Content-Type: application/json` header. Every payload includes these fields:

```
{
  "event": "back_in_stock",
  "timestamp": "2026-03-01T12:00:00Z",
  "data": {
    "product": {
      "handle": "raspberry-pi-5",
      "title": "Raspberry Pi 5",
      "url": "https://store.example.com/products/raspberry-pi-5",
      "price": "95.00",
      "currency": "AUD"
    },
    "variant": {
      "title": "4GB",
      "sku": "RPI5-4GB",
      "available_quantity": 25
    }
  }
}
```

Order events include order details instead of product details:

```
{
  "event": "order_shipped",
  "timestamp": "2026-03-01T14:30:00Z",
  "data": {
    "order": {
      "name": "#1042",
      "status": "fulfilled",
      "tracking_number": "ABC123456",
      "tracking_url": "https://auspost.com.au/track/ABC123456"
    }
  }
}
```

### Verifying webhook signatures

Every webhook request includes an `X-Webhook-Signature` header containing an HMAC-SHA256 signature of the request body, signed with your webhook secret. You should verify this signature to ensure the request genuinely came from us.

```
# Ruby example
signature = OpenSSL::HMAC.hexdigest("SHA256", webhook_secret, request_body)
if Rack::Utils.secure_compare(signature, request_header_signature)
  # Authentic request — process it
end
```

```
# Python example
import hmac, hashlib
signature = hmac.new(
    webhook_secret.encode(), request_body, hashlib.sha256
).hexdigest()
if hmac.compare_digest(signature, request_header_signature):
    # Authentic request — process it
```

### Retry behaviour and failures

If your endpoint returns a non-2xx status code or times out (after 10 seconds), we'll record the failure. After **10 consecutive failures**, the webhook is automatically disabled to avoid unnecessary traffic. You can re-enable it from your [Notifications](/account/notifications) page after fixing the issue.

### Scoping webhooks

By default, a webhook fires for all products matching the selected events. You can narrow it by setting a scope:

- **Product scope** — Only fires for a specific product. Useful if you're monitoring a particular item for restocks.
- **Collection scope** — Only fires for products within a collection. Useful for watching a category like "Sensors" or "Raspberry Pi".

You can set both scopes on the same webhook — it will only fire when both conditions are met.

### Managing your webhooks

All your webhooks are listed on your [Notifications](/account/notifications) page where you can edit, disable, or delete them. If a webhook has been auto-disabled due to failures, you'll see it marked as "Disabled" and can re-enable it after fixing your endpoint.
