Introduction

As Shopify store owners and developers, accessing the {{ customer }} Liquid object is crucial for creating personalized shopping experiences. However, a common issue arises when attempting to access {{ customer.tags }} on Shopify proxy pages, where the customer object may return as empty. This guide explores the reasons behind this issue, recent fixes, and workarounds to help you effectively retrieve customer data on proxy pages.

1. Understanding the Customer Object on Proxy Pages

In Shopify, the customer Liquid object holds key customer data like id, email, and tags. These tags are useful for segmenting customers based on preferences or purchase history. However, the behavior of the customer object changes on proxy pages because it is not automatically accessible due to security and privacy controls, which can lead to empty or missing data.

2. Common Issues with Customer Object Rendering

The main issue developers experience with the {{ customer.tags | json }} Liquid object on proxy pages is that the customer object may appear empty. Here are a few common reasons:

• Privacy Restrictions: Shopify restricts access to sensitive customer data on proxy pages.
• Rendering Delays: Proxy pages sometimes do not immediately recognize logged-in customer data, which can cause delays in loading the customer object.
• Recent Updates or Changes: Shopify may release backend updates that can temporarily affect customer object visibility.

3. Troubleshooting Missing Customer Object

If you encounter issues with the customer object being empty on proxy pages, here are some troubleshooting steps to consider:

1. Test on Theme Files: First, add {{ customer.tags | json }} directly to your theme files, as this can help confirm whether the issue is isolated to the proxy page.
2. Check Shopify Status: Visit Shopify’s status page to see if there are known issues with the Liquid object rendering, especially on proxy pages.
3. Verify Login Status: Ensure the customer is logged in. Without an active login session, the customer object will not contain any data.
4. Contact Shopify Support: If none of these steps resolve the issue, reach out to Shopify Support for further investigation, as it may be a platform-wide issue.

4. Workaround to Retrieve Customer Tags

Before Shopify’s recent fix, there were temporary workarounds that developers could use to display customer tags on proxy pages. Here are a couple of options that proved useful:

• Use AJAX Requests: If the proxy page needs access to customer tags, use JavaScript AJAX calls to retrieve customer data from the main Shopify store instead. This method can bypass some limitations, but it may require additional authentication for security purposes.
• Embed Customer Data in Theme Files: Display the {{ customer.tags | json }} data directly within theme files, then pass it to the proxy page via query parameters or as embedded data in HTML. This method requires careful handling of customer data.

These workarounds are useful when the customer object is temporarily inaccessible but should be handled with caution due to security and privacy considerations.

5. How Shopify Resolved This Issue

Shopify acknowledged the issue with the customer object being inaccessible on proxy pages, affecting several developers and store operations. In response, Shopify released a patch update to resolve the problem in early 2024. Following this update, developers reported that the customer object, including customer.tags, was again accessible on proxy pages without the need for additional workarounds.

If you are still experiencing issues after this update, contact Shopify support to confirm if your store’s proxy pages are fully patched with the latest updates.

6. Best Practices for Future Issues

To minimize disruptions caused by customer object rendering issues, follow these best practices:

• Regularly Check Shopify Status Updates: Shopify periodically rolls out updates that can impact Liquid objects, so it’s essential to keep track of changes via Shopify’s status page or developer updates.
• Test with Staging Environments: Test customer-related changes on a staging site before applying them to your live store to ensure smooth functionality.
• Use Webhooks for Customer Data: If possible, use Shopify’s customer webhooks to trigger events and capture customer data securely. This method bypasses the need to rely solely on the customer object on proxy pages.
• Maintain Backup Code for Proxy Pages: In cases where proxy pages heavily depend on customer data, consider maintaining backup code or workarounds to minimize customer impact if issues arise.

Conclusion

The customer object plays a critical role in delivering personalized experiences on Shopify stores. While Shopify’s recent fix resolves the issue of the customer object on proxy pages, staying informed and prepared for future updates can help maintain seamless store functionality. Follow the best practices above to ensure your store remains functional and customer-friendly, regardless of platform changes.
