Pixel tracking on the post-purchase page
If your store has installed an app that adds a post-purchase page to your store's checkout, then any custom pixel tracking that you use on your store might not capture certain tracking events. Custom tracking pixels that are added to your store's Additional scripts box track events on only the order status page, which comes after the post-purchase page in the checkout. If a customer leaves your store on the post-purchase page, then no events on the order status page are tracked.
To ensure that you capture conversion events properly, you can add a script that tracks events on the post-purchase page. This script can also track additional purchases that are made from the post-purchase page, such as upsells. After you add a post-purchase page script, you need to adjust your order status page script to ignore events that are already captured by the post-purchase page script.
You need to change how your store tracks events only if you use a custom tracking pixel. For example, if you set up Google Analytics through Online Store > Preferences, then it already captures events correctly on your post-purchase page.
On this page
The post-purchase page additional script is similar to the order status page additional scripts, but with a few key differences:
- The script is added to the post-purchase page, not the order status page.
- The only HTML tag allowed is
- The script runs within a sandbox and isn't included on the main page.
- You can add a post-purchase page script only if your store has installed an app that adds a post-purchase page to your checkout.
Running the script within a sandbox ensures that the script is secure and is used for its intended purpose.
Compatibility with scripts on the order status page
To ensure that your pixels correctly track all conversion events, set up tracking scripts on both the post-purchase page and the order status page. To avoid counting conversion events twice, you can use the
post_purchase_page_accessed Liquid variable in scripts that run on the order status page.
If a customer lands on the post-purchase page and then navigates to the order status page, then the
post_purchase_page_accessed variable returns
true. If a customer doesn't arrive at the post-purchase page, then the variable returns
For example, you can use the following format for your scripts on the order status page:
Tracking purchases made on the post-purchase page
To track additional purchases that are made through the post-purchase page, you can subscribe to the
After you subscribe, the following actions occur whenever a post-purchase changeset is successfully applied:
- Your handler is called with two
- The globals under
window.Shopifyare updated so that the scripts can use the updated data.
Handlers subscribed to this event can have as little as 500 ms to execute. Make sure to load any dependencies that you need ahead of time.
Add the post-purchase page script
Before you add the post-purchase page script, for the post-purchase field to display in your Shopify Admin, make sure that you set up either the Google and YouTube channel or download a third party post-purchase app.
- From your Shopify admin, go to Settings > Checkout.
- In the Post-purchase additional scripts field, enter your script.
- Click Save.
You can use the following basic script template to help you build your own post-purchase page script. This example script uses Google Analytics to track the initial conversion, and explains how to track additional purchases. This example is very simple and your final script will likely differ from it.
