# BigCommerce Webhooks

## When to Use This Skill

- How do I receive BigCommerce webhooks?
- How do I verify BigCommerce webhook signatures?
- How do I handle store/order/created or store/order/statusUpdated events?
- Why is my BigCommerce webhook signature verification failing?
- How do I create a BigCommerce webhook via the API?

## How BigCommerce Webhooks Work

BigCommerce webhooks are created **via API only** (no dashboard UI):
`POST /stores/{store_hash}/v3/hooks` with an `X-Auth-Token` OAuth access token.

Payloads are **thin** — `data` carries only the resource `type` and `id`. Read
the event from `scope` and call the REST API back to fetch the full resource:

```json
{
  "store_id": "1000",
  "producer": "stores/abc123",
  "scope": "store/order/statusUpdated",
  "data": { "type": "order", "id": 173331 },
  "hash": "…",
  "created_at": 1561479335
}
```

Respond **HTTP 200 immediately**; do slow work asynchronously. Failed deliveries
retry over ~48h, after which the hook is deactivated. If a domain's success
ratio drops below 90% in a 2-minute window it is blocklisted for 3 minutes.

## Verification (core)

BigCommerce documents callback signing per the **Standard Webhooks** spec and
recommends verifying with Standard Webhooks libraries. The spec's headers are
`webhook-id`, `webhook-timestamp`, and `webhook-signature` (`v1,<base64>`),
with the signature computed as HMAC-SHA256 over
`{webhook-id}.{webhook-timestamp}.{rawBody}` — note BigCommerce's own docs
don't currently name the headers explicitly, state whether the feature is GA,
or clarify whether signatures apply to all hooks or only app-created hooks.
Log incoming headers on your first delivery to confirm. If signatures aren't
present on your hooks, fall back to **custom headers** set at hook creation
(see `references/setup.md`).

The signing key is your app's **client secret, base64-encoded** — the
`standardwebhooks` library base64-decodes whatever you pass, so encoding the
client secret first makes the raw client-secret bytes the HMAC key. Pass the
**raw** request body — don't `JSON.parse` first.

Node:

```javascript
const { Webhook } = require('standardwebhooks');

// base64-encode the client secret; the library decodes it back to raw bytes
const wh = new Webhook(Buffer.from(process.env.BIGCOMMERCE_CLIENT_SECRET).toString('base64'));

const event = wh.verify(rawBody, {          // rawBody = Buffer/string of the HTTP body
  'webhook-id': req.headers['webhook-id'],
  'webhook-timestamp': req.headers['webhook-timestamp'],
  'webhook-signature': req.headers['webhook-signature'],
});
// Throws WebhookVerificationError on tampering or a stale timestamp
```

Python:

```python
import base64
from standardwebhooks.webhooks import Webhook

wh = Webhook(base64.b64encode(os.environ["BIGCOMMERCE_CLIENT_SECRET"].encode()).decode())

event = wh.verify(raw_body, {               # raw_body = bytes of the HTTP body
    "webhook-id": headers["webhook-id"],
    "webhook-timestamp": headers["webhook-timestamp"],
    "webhook-signature": headers["webhook-signature"],
})
# Raises WebhookVerificationError on tampering or a stale timestamp
```

## Common Event Types

Dispatch on the `scope` field:

| Scope | Triggered When |
|-------|----------------|
| `store/order/created` | An order is created (storefront, control panel, app, or API) |
| `store/order/updated` | Any field on an order changes |
| `store/order/statusUpdated` | An order's status changes |
| `store/product/created` | A product is added |
| `store/product/updated` | A product's attributes change |
| `store/product/deleted` | A product is removed |
| `store/product/inventory/updated` | Base product stock level changes |
| `store/customer/created` | A new customer registers |
| `store/cart/created` | A new cart is created |
| `store/cart/abandoned` | A cart sees no activity for 1+ hour |

> **For the full scope reference**, see [BigCommerce Webhook Events](https://developer.bigcommerce.com/docs/integrations/webhooks/events).

## Environment Variables

```bash
BIGCOMMERCE_CLIENT_SECRET=your_client_secret   # signs/verifies webhooks
# Needed only to call the REST API back for full resource details:
# BIGCOMMERCE_STORE_HASH=abc123
# BIGCOMMERCE_ACCESS_TOKEN=your_access_token
```

## Local Development

BigCommerce requires an HTTPS endpoint on port 443, so tunnel to your local
server. The Hookdeck CLI runs via `npx` — no install, no account required:

```bash
npx hookdeck-cli listen 3000 bigcommerce --path /webhooks/bigcommerce
```

Then point a hook at the tunnel URL:

```bash
curl -X POST https://api.bigcommerce.com/stores/{store_hash}/v3/hooks \
  -H "X-Auth-Token: {access_token}" \
  -H "Content-Type: application/json" \
  -d '{"scope":"store/order/created","destination":"https://<url>/webhooks/bigcommerce","is_active":true}'
```

New hooks can take up to a minute to activate.

## Recommended: webhook-handler-patterns

We recommend installing the [webhook-handler-patterns](https://github.com/hookdeck/webhook-skills/tree/main/skills/webhook-handler-patterns) skill alongside this one for handler sequence, idempotency, error handling, and retry logic. Key references (open on GitHub):

- [Handler sequence](https://github.com/hookdeck/webhook-skills/blob/main/skills/webhook-handler-patterns/references/handler-sequence.md) — Verify first, parse second, handle idempotently third
- [Idempotency](https://github.com/hookdeck/webhook-skills/blob/main/skills/webhook-handler-patterns/references/idempotency.md) — Prevent duplicate processing (use the payload `hash` field)
- [Error handling](https://github.com/hookdeck/webhook-skills/blob/main/skills/webhook-handler-patterns/references/error-handling.md) — Return codes, logging, dead letter queues
- [Retry logic](https://github.com/hookdeck/webhook-skills/blob/main/skills/webhook-handler-patterns/references/retry-logic.md) — Provider retry schedules, backoff patterns
