Understanding Shopify‘s Customer Privacy API: A Brief Guide
1. Set Up Data Access Limits
Shopify’s 2022-10 API offers a three-tier permission system that helps you control how fulfillment apps access data:
| Access Level | Data Type | Approval Required | Typical Use Case |
|---|---|---|---|
| Level 0 | No customer data | No | Basic store analytics |
| Level 1 | Non-PII order/cart data | No | Inventory tracking |
| Level 2 | Name/address/phone/email | Yes | Order fulfillment |
To set up effective data access controls, focus on these key areas:
Time-Based Restrictions
Instead of granting "All Orders" access, use the "Recent Orders" permission. This limits data access to the last 60 days, which is usually enough for most fulfillment tasks [2]. It reduces exposure to older data without disrupting operations.
Role-Based Controls
Set up admin accounts specifically for apps, separate from those used by individuals [3]. Use Shopify’s staff permissions to limit "Manage apps" access to only those who need it.
API Security Measures
Enable IP allowlisting and enforce 60-day OAuth token expirations [4]. This ensures that only approved networks can use your fulfillment app’s API endpoints, adding an extra layer of protection.
Steps to Verify Permissions
- Go to Settings > Apps and sales channels
- Click "…" > View details for your fulfillment app
- Check "Permission details" for API scopes
- Review "Privacy details" for any personal data categories [4]
Mistakes to Watch Out For
- Granting "All Orders" access when "Recent Orders" is enough
- Allowing write permissions without a clear need for them
These controls lay the groundwork for secure and compliant data handling. Next, we’ll cover how to align your data storage practices with these permissions.
2. Check App Data Storage Rules
After setting up data access limits, it’s important to check how fulfillment apps handle and store customer data. Shopify offers tools to help you monitor and control these practices effectively.
Review Storage Duration Policies
Every app on Shopify must disclose how long they retain data. You can find this information in these places:
| Location | What to Check | When to Review |
|---|---|---|
| App Store Listing | Initial privacy details | Before installation |
| Settings > Apps | Full data handling details | After installation and quarterly |
| Permission Details | API access scopes | Monthly monitoring |
Signs of Proper Storage Compliance
When evaluating fulfillment apps, look for these key indicators:
- Defined retention timelines (usually 30–90 days after delivery)
- Clear details on where the data is stored
- Automatic triggers for data deletion
- Documentation of encryption methods used
Red Flags to Watch For
Be cautious with apps that:
- Request access to historical orders older than 60 days
- Lack encryption documentation
- Have vague or undefined data deletion processes
- Do not clearly state retention periods
Conduct Regular Storage Audits
Combine monthly API permission checks (covered in Section 1) with quarterly storage audits to ensure compliance:
- Compare the app’s storage policies with Shopify’s API logs (e.g.,
order/customer.last_api_access) [3]. - Test data deletion requests to confirm they are completed within 30 days.
Data Storage Requirements by Region
- EU/EEA: Data must be stored on servers within EU borders.
- UK: Ensure data centers comply with GDPR regulations.
- Global: Require AES-256 encryption certification for secure storage.
Use Shopify’s Compliance Tools
Shopify provides built-in features to help you stay on top of data storage rules:
- Tools for data removal
- API access timestamps
- Notifications for permission changes
- Automated alerts for compliance issues
Once you’ve verified storage practices, focus on setting up clear consent tracking to ensure compliance throughout the fulfillment process.
3. Set Up Customer Consent Tracking
Once you’ve confirmed your data storage practices are in order, the next step is to set up systems to track customer consent. This ensures you’re compliant during every stage of order processing.
Key Components for Consent Management
A good consent tracking system includes three main technical elements:
| Component | Purpose | Implementation Method |
|---|---|---|
| Preference Center | Allows customers to choose how their data is used | Provide clear yes/no options for data usage |
| Consent History | Keeps a record of customer decisions | Securely store timestamped records |
| API Integration | Ensures real-time updates | Use Shopify compliance webhooks |
Required Shopify Webhooks
Shopify mandates that fulfillment apps include these webhooks [4]:
customers/data_request: Handles requests for customer data access.customers/redact: Manages requests to delete customer data.shop/redact: Handles store-wide data removal requests.
Best Practices for Consent Tracking
Set up separate consent processes for different workflows, such as shipping and returns [3]. This detailed approach keeps operations running smoothly while staying compliant.
Compliance Metrics to Monitor
Regularly check these metrics to ensure compliance:
| Metric | Requirement | Monitoring Frequency |
|---|---|---|
| Consent Refresh | Update every 6 months | Check monthly |
| Deletion Response | Complete within 48 hours | Monitor daily |
| System Sync Rate | Maintain 99.9% accuracy | Audit weekly |
Data Access Controls
Limit data access strictly based on the consent status of each customer.
Testing and Validation
Before launching, test scenarios like partial consents or delayed deletions using Shopify’s App Bridge tools. This ensures your system stays compliant while keeping fulfillment efficient [1].
"Apps must respond to data subject requests, even if they don’t collect personal data" [4]
4. Use Strong Data Encryption
Encryption plays a key role in safeguarding data during processing, complementing consent tracking for usage permissions. Here’s what you need to know to implement it effectively:
Encryption Implementation Standards
| Data Type | Encryption Method | Key Management |
|---|---|---|
| At Rest | AES-256 | Stored in HSMs |
| In Transit | TLS 1.2+ | Standard key rotation |
| Emails/Addresses | End-to-end + AES-256 | Managed with separate keys |
| Order Details | TLS 1.3 | Rotated quarterly |
Key Management Practices
Follow these guidelines to align with Shopify’s security framework:
- Keep production and test environment keys separate.
- Rotate encryption keys every 90 days.
- Use Hardware Security Modules (HSMs) for secure key storage in enterprise settings.
Common Implementation Pitfalls
Avoid these frequent mistakes when setting up encryption for fulfillment apps:
- Storing Keys in Code: Never store encryption keys in code repositories. Instead, use environment variables.
- Outdated Protocols: Ensure all connections use at least TLS 1.2.
- Unprotected Backups: Always encrypt database backups, especially those containing sensitive customer information like addresses.
Verification Methods
Merchants can verify encryption measures by:
