Shopify Data Handling

Name: shopify-data-handling
Author: jeremylongshore

Overview

Handle customer PII correctly when building Shopify apps. Covers the mandatory GDPR webhooks, data minimization, and the specific privacy requirements Shopify enforces for App Store submission.

Prerequisites

Understanding of GDPR/CCPA requirements
Shopify app with webhook handling configured
Database for storing and deleting customer data

Instructions

Step 1: Understand What Data Shopify Shares

When a merchant grants your app access, you may receive:

Data Type	Source	Sensitivity	Retention Obligation
Customer email, name, phone	`read_customers` scope	PII — encrypt at rest	Delete on `customers/redact`
Shipping addresses	`read_orders` scope	PII — encrypt at rest	Delete on `customers/redact`
Order details (amounts, items)	`read_orders` scope	Business data	Delete on `shop/redact`
Product data	`read_products` scope	Public	Delete on `shop/redact`
Shop owner email	`read_shop` scope	PII	Delete on `shop/redact`

Step 2: Implement Mandatory Privacy Webhooks

Shopify requires three GDPR webhooks for App Store apps. Your app will be rejected without them: customers/data_request (customer wants their data), customers/redact (delete a customer's PII), and shop/redact (delete all shop data 48h after uninstall).

See GDPR Privacy Webhooks for the complete implementation of all three handlers.

Step 3: Data Minimization and PII Detection

Only fetch the fields you actually use in GraphQL queries. Add PII redaction middleware to prevent customer data from leaking into logs — detect emails, phone numbers, and credit card patterns.

See Data Minimization and PII Detection for query examples and redaction middleware.

Step 4: Data Retention Policy

Automate cleanup with a daily cron job: delete API logs after 30 days, webhook logs after 90 days, and keep audit logs for 7 years (regulatory requirement).

See Data Retention Policy for the complete implementation.

Output

GDPR mandatory webhooks implemented and tested
Data minimization in API queries
PII redaction in all log output
Retention policy with automatic cleanup

Error Handling

Issue	Cause	Solution
App Store rejection for GDPR	Missing webhook handlers	Implement all 3 mandatory webhooks
Customer data not found	Data already deleted	Return empty response (not an error)
shop/redact not received	App reinstalled before 48h	Shopify cancels redact if reinstalled
PII in logs	Missing redaction	Add redaction middleware to all loggers

Examples

Test GDPR Webhooks

# Simulate a customers/data_request webhook locally
curl -X POST http://localhost:3000/webhooks/gdpr/data-request \
  -H "Content-Type: application/json" \
  -H "X-Shopify-Topic: customers/data_request" \
  -H "X-Shopify-Shop-Domain: test.myshopify.com" \
  -d '{
    "shop_domain": "test.myshopify.com",
    "customer": {"id": 123, "email": "test@example.com", "phone": "+1234567890"},
    "orders_requested": [1001, 1002],
    "data_request": {"id": 999}
  }'
