| 3 | ## When to Use This Skill |
| 4 | |
| 5 | - Setting up Shopify webhook handlers |
| 6 | - Debugging signature verification failures |
| 7 | - Understanding Shopify event types and payloads |
| 8 | - Handling order, product, or customer events |
| 9 | |
| 10 | ## Verification (core) |
| 11 | |
| 12 | 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`. |
| 13 | |
| 14 | Node: |
| 15 | |
| 16 | ```javascript |
| 17 | const crypto = require('crypto'); |
| 18 | |
| 19 | function verify(rawBody, hmacHeader, secret) { |
| 20 | if (!hmacHeader) return false; |
| 21 | const expected = crypto.createHmac('sha256', secret).update(rawBody).digest('base64'); |
| 22 | try { |
| 23 | return crypto.timingSafeEqual(Buffer.from(hmacHeader), Buffer.from(expected)); |
| 24 | } catch { |
| 25 | return false; |
| 26 | } |
| 27 | } |
| 28 | ``` |
| 29 | |
| 30 | Python: |
| 31 | |
| 32 | ```python |
| 33 | import hmac, hashlib, base64 |
| 34 | |
| 35 | def verify(raw_body: bytes, hmac_header: str, secret: str) -> bool: |
| 36 | if not hmac_header: |
| 37 | return False |
| 38 | expected = base64.b64encode( |
| 39 | hmac.new(secret.encode(), raw_body, hashlib.sha256).digest() |
| 40 | ).decode() |
| 41 | return hmac.compare_digest(hmac_header, expected) |
| 42 | ``` |
| 43 | |
| 44 | > **Important**: Shopify requires the endpoint to respond with 200 within 5 seconds. Process work asynchronously if the handler is slow. |
| 45 | |

| 51 | ## Common Event Types (Topics) |
| 52 | |
| 53 | | Topic | Description | |
| 54 | |-------|-------------| |
| 55 | | `orders/create` | New order placed | |
| 56 | | `orders/updated` | Order modified | |
| 57 | | `orders/paid` | Order payment received | |
| 58 | | `orders/fulfilled` | Order shipped | |
| 59 | | `products/create` | New product added | |
| 60 | | `products/update` | Product modified | |
| 61 | | `customers/create` | New customer registered | |
| 62 | | `app/uninstalled` | App removed from store | |
| 63 | |
| 64 | > **For full topic reference**, see [Shopify Webhook Topics](https://shopify.dev/docs/api/admin-rest/current/resources/webhook) |
| 65 | > |
| 66 | > **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. |
