Track SKU Products or Subscriptions Separately in Shopify

Learn how to track subscriptions and individual product SKUs in Shopify using Convert’s native app or manual integration with custom JavaScript.

🔄 Tracking Subscriptions via the Convert Shopify App

Nowadays, subscriptions can be tracked via the Convert Shopify App.
For detailed integration instructions, see:
👉 Integrate with Shopify through our custom Convert App

The app creates two subscription goals:

One for tracking Subscription transactions
One for Non-Subscription transactions

These goals must be linked to existing goals in Convert. To set this up:

Create a Custom JS goal for each type (subscription and non-subscription)
Link them within the Shopify App goals tab

🚨 Important Note: This integration classifies a transaction as a subscription if there are ANY subscription articles in the transaction, and non-subscription if there are none. This differs from separating subscription and non-subscription articles into different transactions.

📦 Tracking Specific Products Separately by SKU

To track specific products separately by SKU, use the Manual Shopify Installation method:
👉 Integrating Convert Experiences with Shopify

⚠️ This is not intended to track all products separately by SKU—only one or two that are important to you.

For this, replace the Customer Event Pixel with the following custom code:
