Overview
Understanding where your conversions come from is critical for scaling marketing performance. However, traditional tracking methods often lose attribution data due to redirects, cookie limitations, and fragmented user journeys.
The Polar App Embed solves this by keeping users within your environment while preserving attribution data across the entire funnel.
In this article, we’ll cover:

What is the Polar App Embed?
The Polar app embed is a theme extension that enables a critical data flow: passing visitor session information from the frontend of your storefront directly to the Shopify backend. This ensures that valuable session data is integrated into the actual order data. For headless store implementation, skip to the last section.
How It Reduces "Undefined" Attribution
A common challenge in modern e-commerce is when customers use checkouts that entirely bypass the traditional Shopify frontend checkout process. This creates a "gap" in attribution:
The Polar pixel captures the initial visit event on the storefront.
The user checks out via a method where the standard frontend pixel cannot run.
The frontend pixel never receives the purchase event, breaking the link between the initial visit and the final order. The order appears, but its source is "undefined."
The Polar app embed solves this. By proactively injecting session data directly into the order at the cart level on the backend, we guarantee that the session information is captured regardless of which checkout system is used. Even if the customer bypasses the standard Shopify checkout, the necessary data is already attached to their order, ensuring accurate attribution and eliminating the "undefined" state.
How to Enable the App Embed (Step-by-Step)
Enabling the app embed takes only a moment in your Shopify theme settings.
Navigate to the pixel-setup page from the connectors page or the acquisition tab
Follow the link "Enable app embed"
Toggle to On and save: Ensure the toggle is set to ON for the Polar app and save
Once saved, the app embed is active:
Implementation for Headless Stores
If you are running a Headless store, you cannot use the Shopify theme app embed. However, you can (and should) achieve the same result.
For headless architectures, we have documented the exact logic needed to manually inject session data into the cart.
Please consult our SDK Documentation, specifically the section titled "Cart Attribute Injection." This will guide you through the process of manually linking session data to orders in your custom storefront setup.
Conclusion
By embedding Polar directly into your site, you eliminate common attribution gaps and gain a clearer, more reliable view of your customer journey. This leads to more accurate performance insights, better budget allocation, and ultimately stronger marketing results. As attribution continues to evolve in a privacy-first world, using solutions like the Polar App Embed ensures you’re making decisions based on complete and trustworthy data.
