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.
Email the instructions to your developer
If a developer or agency manages your website and you can’t edit it yourself, send them the installation instructions straight from Dash.fi. The Install tracking pixel step in the Ad Agent setup flow and the pixel installation section under Agents → Advertising → Configure both include this option.
Open the email form
Below the pixel code, find the Don’t have site access? card and click Email developer.
Enter your developer's email
Enter the email address of the person who will install the pixel, such as developer@agency.com.
Send the instructions
Click Send instructions. Dash.fi emails your developer the pixel code and how to install it, and shows a confirmation once the email is sent.
Sending instructions requires permission to manage agents in your Dash.fi account. If sending fails, ask an account admin to check your permissions.
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.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>. 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 at support@dash.fi with your site URL and the installation method you used.
