Secure Shopify applications — HMAC webhook verification, session token validation, OAuth scope management, Content Security Policy, GDPR mandatory webhooks, input validation, and secure coding practices. Use when implementing Shopify security features.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Shopify Security
## Before writing code
**Fetch live docs**:
1. Web-search `site:shopify.dev security best practices` for security guidelines
2. Web-search `site:shopify.dev webhook verification hmac` for HMAC implementation
3. Web-search `site:shopify.dev session token` for session token verification
## HMAC Webhook Verification
Every webhook includes `X-Shopify-Hmac-SHA256`:
```typescript
import crypto from 'crypto';
function verifyShopifyWebhook(
rawBody: Buffer,
hmacHeader: string,
secret: string,
): boolean {
const calculated = crypto
.createHmac('sha256', secret)
.update(rawBody)
.digest('base64');
return crypto.timingSafeEqual(
Buffer.from(calculated),
Buffer.from(hmacHeader),
);
}
```
**Critical:** Use `timingSafeEqual` to prevent timing attacks. Use raw body buffer, not parsed JSON.
## Session Token Verification
For embedded apps using App Bridge:
```typescript
import jwt from 'jsonwebtoken';
function verifySessionToken(token: string, apiSecret: string) {
const decoded = jwt.verify(token, apiSecret, {
algorithms: ['HS256'],
});
// Verify issuer is a valid Shopify shop
const iss = decoded.iss as string;

How to install
mdr add orcaqubits/agentic-commerce-skills-plugins/shopify-security@sha256:b7c5bf5235927ccaThe line at the top of this page pins the label git:20260325.a7816e7, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
