Install the Ad Pay Protection pixel

The Ad Pay Protection (A.P.P.) pixel is a lightweight JavaScript snippet that tracks user events on your website and correlates them with your ad platform data for real-time auditing and fraud detection. Your unique pixel script is provided by your Dash.fi Customer Success Manager during your implementation call. Once you have the script, follow the instructions below for your platform.

If you haven’t received your pixel script yet, contact your Customer Success Manager or email support@dash.fi before proceeding.

Installation methods

Choose the tab that matches how your website is built or managed.

Google Tag Manager
Shopify
Manual HTML

Google Tag Manager (GTM) is the recommended method if you already use GTM on your site, as it lets you deploy and update the pixel without touching your site’s code directly.

Open Google Tag Manager

Go to tagmanager.google.com and select the account and container where you want to install the pixel.

Create a new tag

Click New Tag and give the tag a descriptive name (e.g., Dash.fi Ad Pay Protection).

Configure the tag

Set the following options:

Tag Type: Custom HTML
HTML: Paste your full pixel script into the HTML field
Triggering: All Pages

Save the tag

Click Save to store the tag configuration.

Publish the container

Click Submit in the top navigation bar, add a version name or description if prompted, and publish. The pixel is now live on all pages.

After publishing, use GTM’s Preview mode to verify the tag fires correctly on page load before closing your session.

If your storefront runs on Shopify, you can add the pixel directly to your theme’s theme.liquid file so it loads on every page automatically.

Always back up your theme before editing code. In Shopify Admin, go to Online Store > Themes, click the three-dot menu on your active theme, and select Duplicate to create a backup copy.

Open the theme code editor

In Shopify Admin, go to Online Store > Themes. Click the three-dot menu (or Actions) on your active theme, then select Edit code.

Open theme.liquid

In the Layout folder on the left, click theme.liquid to open the file.

Locate the closing head tag

Use your browser’s find function (Ctrl+F / Cmd+F) to locate the closing </head> tag in the file.

Paste the pixel script

Paste your pixel script on a new line directly above the </head> tag.

Save the file

Click Save. The pixel will now load on every page of your Shopify store.

If you manage your website’s HTML directly, you can add the pixel manually to each page or to a shared header file.

Always back up your HTML files before making edits. Keep a copy of the original files in a safe location before you begin.

Identify files to edit

Determine which HTML files need the pixel. If your site uses a shared header or layout file, you only need to edit that one file. Otherwise, identify every individual page you want to track.

Open the file in a text editor

Open the target HTML file in your preferred text or code editor.

Locate the closing head tag

Find the closing </head> tag in the file.

Paste the pixel script

Paste your pixel script on a new line immediately before </head>.

<!-- Dash.fi Ad Pay Protection Pixel -->
<!-- Paste your pixel script here -->
</head>

Save and upload

Save the file and upload it to your web server, replacing the existing version. Repeat this process for all pages if there is no shared header file.

Verifying installation

After installing the pixel, confirm it’s firing. Load a page on your site and open your browser’s developer tools (Network tab) — look for a request to the Dash.fi pixel endpoint. Your Customer Success Manager can also confirm receipt of pixel events on the Dash.fi side.

If you need help verifying your pixel installation, contact support@dash.fi with your site URL and the installation method you used.
