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:

{
  "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:

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:

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.

Environment Variables

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:

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

Then point a hook at the tunnel URL:

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.

We recommend installing the webhook-handler-patterns skill alongside this one for handler sequence, idempotency, error handling, and retry logic. Key references (open on GitHub):

• Handler sequence — Verify first, parse second, handle idempotently third
• Idempotency — Prevent duplicate processing (use the payload hash field)
• Error handling — Return codes, logging, dead letter queues
• Retry logic — Provider retry schedules, backoff patterns
