Install on Shopify
Shopify is the simplest install. The tracking code goes into your theme’s theme.liquid file, and Shopify automatically loads it on every page of your store.
This page only covers installing the basic tracking pixel. If you want PartialLeads to capture purchase events from your Shopify store (and send them to Meta, Pinterest, Google Ads), you also need to connect the Shopify integration — see the E-Commerce guide.
Step-by-step
Open your Shopify admin
Log into your Shopify admin at https://admin.shopify.com.
Go to Themes
In the left sidebar, click Online Store, then click Themes.
You’ll see your active theme at the top of the page.
Edit your theme code
Next to your active theme, click Actions, then Edit code.
A code editor opens with a list of files on the left.
Open theme.liquid
In the file list, scroll to the Layout section and click theme.liquid.
This is your store’s master template. Whatever you put here loads on every page.
Paste the tracking code
Find the closing </head> tag (use Ctrl+F or Cmd+F to search if you can’t see it).
Paste the PartialLeads tracking code on a new line right before </head>. So the result looks like:
...other stuff in your head...
<script>window.PartialLeadsConfig={apiKey:"pl_yourkey"};</script>
<script src="https://api.partialleads.com/px-universal.js" async></script>
</head>Click Save
Click the Save button in the top-right of the code editor.
The change is live immediately — no need to publish anything.
How to know it’s working
Open your store’s homepage in a new incognito or private browser tab. Then go back to your PartialLeads dashboard’s Setup page.
Within 5 seconds, the verification panel should switch from Waiting for first signal to Script installed.
If it doesn’t, see Troubleshooting.
What about checkout events?
The basic tracking pixel only sees pages on your storefront — your home page, product pages, collection pages, blog posts. It does not see what happens inside Shopify’s checkout (Shopify locks checkout down to their own pixel system).
If you want to capture checkout abandons and purchase events, you need the full Shopify integration. It uses Shopify’s separate “Customer Events” pixel system plus webhook subscriptions. See the E-Commerce guide for the full setup.
