## About

# Shopify Webhooks

## When to Use This Skill

- Setting up Shopify webhook handlers
- Debugging signature verification failures
- Understanding Shopify event types and payloads
- Handling order, product, or customer events

## Verification (core)

Shopify signs the raw body with HMAC-SHA256 keyed on the app's API secret and sends the digest in `X-Shopify-Hmac-SHA256` as **base64** (not hex). Pass the **raw** body, decode base64, and compare timing-safe. The topic is in `X-Shopify-Topic`; the shop domain in `X-Shopify-Shop-Domain`.

Node:

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

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

Python:

```python
import hmac, hashlib, base64

def verify(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(hmac_header, expected)
```

> **Important**: Shopify requires the endpoint to respond with 200 within 5 seconds. Process work asynchronously if the handler is slow.

## Common Event Types (Topics)

| Topic | Description |
|-------|-------------|
| `orders/create` | New order placed |
| `orders/updated` | Order modified |
| `orders/paid` | Order payment received |
| `orders/fulfilled` | Order shipped |
| `products/create` | New product added |
| `products/update` | Product modified |
| `customers/create` | New customer registered |
| `app/uninstalled` | App removed from store |

>
> **Note**: While the REST Admin API is becoming legacy for apps created after April 1, 2025, existing apps can continue using the REST API. New apps should consider using the [GraphQL Admin API](https://shopify.dev/docs/api/admin-graphql) for webhook management.

## 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
- [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
