# ShipBob Webhooks

## When to Use This Skill

- Setting up ShipBob webhook handlers
- Debugging ShipBob signature verification failures
- Understanding ShipBob event types (topics) and payloads
- Handling fulfillment, shipment, return, receiving (WRO), or billing events

## Verification (core)

ShipBob signs webhooks with the [Standard Webhooks](https://www.standardwebhooks.com/)
scheme (the same fields Svix uses). It sends three headers — `webhook-id`,
`webhook-timestamp`, and `webhook-signature` — and the **event topic** in a
separate `x-webhook-topic` header (e.g. `order.shipped`).

The signature is `HMAC-SHA256(secret, "{webhook-id}.{webhook-timestamp}.{body}")`,
base64-encoded. The signing secret is `whsec_<base64>` — strip the `whsec_`
prefix and **base64-decode the remainder** to get the raw HMAC key. Always verify
against the **raw, unmodified** request body (don't `JSON.parse` first).
`webhook-signature` holds space-delimited versioned signatures (`v1,<sig>`);
compare against the `v1` entry with a timing-safe comparison.

Node (via the `standardwebhooks` package, which handles the secret decode and
multi-signature parsing for you):

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

const wh = new Webhook(process.env.SHIPBOB_WEBHOOK_SECRET); // whsec_...
// rawBody is a Buffer/string; headers use the Standard Webhooks names
const event = wh.verify(rawBody, {
  '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
const topic = req.headers['x-webhook-topic']; // e.g. "order.shipped"
```

Python (manual — there is no official ShipBob SDK):

```python
import hmac, hashlib, base64

def verify(body: bytes, webhook_id, webhook_timestamp, webhook_signature, secret):
    signed = f"{webhook_id}.{webhook_timestamp}.{body.decode()}".encode()
    key = base64.b64decode(secret.split("_", 1)[1])  # strip 'whsec_' then base64-decode
    expected = base64.b64encode(hmac.new(key, signed, hashlib.sha256).digest()).decode()
    sent = [s.split(",", 1)[1] for s in webhook_signature.split(" ") if "," in s]
    return any(hmac.compare_digest(expected, s) for s in sent)  # timing-safe
```

## Common Event Types

The topic arrives in the `x-webhook-topic` header (current API uses dotted names;
legacy 1.0/2.0 used underscores like `order_shipped`).

| Topic | Triggered When | Read scope |
|-------|----------------|------------|
| `order.shipped` | An order's shipment ships | `orders_read` / `fulfillments_read` |
| `order.shipment.delivered` | A shipment is delivered | `orders_read` / `fulfillments_read` |
| `order.shipment.tracking.updated` | Tracking info changes | `orders_read` / `fulfillments_read` |
| `order.shipment.exception` | A shipment hits an exception | `orders_read` / `fulfillments_read` |
| `return.created` | A return is created | `returns_read` |
| `wro.created` | A Warehouse Receiving Order is created | `receiving_read` |
| `billing.charge.created` | A billing charge is created | `billing_read` |

> **For the full topic list**, see [ShipBob's webhook documentation](https://developer.shipbob.com/2026-01/webhooks).

## Environment Variables

```bash
SHIPBOB_WEBHOOK_SECRET=whsec_xxxxx   # Signing secret from the webhook subscription
```

## Subscribing

Subscribe via the API with `POST /2026-01/webhook` and a body of
`{ "topics": ["order.shipped", ...], "url": "https://your.app/webhooks/shipbob" }`.
Requires the `webhooks_write` scope plus the read scope for each topic (see the
table above). See [references/setup.md](references/setup.md) for details.

## Local Development

```bash
# Start tunnel (no account needed)
npx hookdeck-cli listen 3000 shipbob --path /webhooks/shipbob
```

## 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 (ShipBob may retry; dedupe on `webhook-id`)
- [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
