# ShipHero Webhooks

## When to Use This Skill

- How do I receive ShipHero webhooks?
- How do I verify ShipHero webhook signatures?
- How do I handle Order Allocated, Shipment Update, or Inventory Update events?
- Why is my ShipHero webhook signature verification failing?
- How do I register a ShipHero webhook with the `webhook_create` mutation?

## Verification (core)

ShipHero signs each webhook with **HMAC-SHA256 over the raw JSON request body**, base64-encoded, sent in the `x-shiphero-hmac-sha256` header. The key is the app's `shared_signature_secret`, returned **once** by the `webhook_create` mutation. Verify by recomputing `base64(HMAC-SHA256(rawBody, secret))` and comparing timing-safe against the header. Pass the **raw** body — parsing JSON first will break the signature. This is a plain HMAC of the raw body (NOT payload-concatenated-with-account-id, NOT Standard Webhooks).

There is no topic header — dispatch on the `webhook_type` field inside the (verified) payload. `X-Shiphero-Message-ID` is a unique per-delivery id for deduplication.

Node:

```javascript
const crypto = require('crypto');

function verifyShipHeroWebhook(rawBody, hmacHeader, secret) {
  if (!hmacHeader) return false;
  const expected = crypto.createHmac('sha256', secret).update(rawBody).digest('base64');
  try {
    return crypto.timingSafeEqual(Buffer.from(expected), Buffer.from(hmacHeader));
  } catch {
    return false;
  }
}
```

Python:

```python
import hmac, hashlib, base64

def verify_shiphero_webhook(raw_body: bytes, hmac_header: str, secret: str) -> bool:
    if not hmac_header:
        return False
    expected = base64.b64encode(
        hmac.new(secret.encode(), raw_body, hashlib.sha256).digest()
    ).decode()
    return hmac.compare_digest(expected, hmac_header)
```

> **Respond quickly**: ShipHero uses a ~10s timeout (20s for Generate Label) and retries up to 5 times per trigger. Respond `2xx` with body `{"code": "200", "Status": "Success"}` and process work asynchronously if slow. Note: ShipHero does **not** queue events while a webhook is disabled — they are discarded.

## Common Webhook Types

ShipHero webhook type names are Title Case strings. The registered `name` (in `webhook_create`) matches the `webhook_type` field in the payload.

| Webhook Type | Triggered When |
|--------------|----------------|
| `Order Allocated` | Inventory is allocated to an order |
| `Shipment Update` | An order ships (tracking, carrier, packages) |
| `Inventory Update` | On-hand / available inventory changes |
| `Order Canceled` | An order is canceled |
| `PO Update` | A purchase order changes state |
| `Return Update` | A return (RMA) is created or updated |
| `Tote Complete` | A pick tote is completed |
| `Package Added` | A package is added to a shipment |

> **For the full list** (Inventory Change, Order Deallocated, Order Packed Out, Capture Payment, Generate Label, Print Barcode, Tote Cleared, Automation Rules, Shipment ASN, Work Order Status Update), see [references/overview.md](references/overview.md) and [ShipHero Webhooks docs](https://developer.shiphero.com/webhooks/).

## Environment Variables

```bash
SHIPHERO_WEBHOOK_SECRET=your_shared_signature_secret   # shared_signature_secret from webhook_create
```

## Local Development

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