Overview

Webflow allows you to add custom code to your website through the Custom Code settings in both the Designer and Site Settings. You can add the CustomerOS tracker to your entire site or to individual pages.

​
Installation

Find the HTML Snippet in the CustomerOS app to add to your website. It is specific to your domain so that you aren’t blocked by adblockers and privacy modes. To add the tracker to your entire Webflow site:
  1. Open your Webflow project in the Designer
  2. Click on Settings (gear icon) in the left sidebar
  3. Navigate to the Custom Code tab
  4. Under Head Code, paste the CustomerOS tracker script
  5. Click Save Changes
  6. Publish your site for the changes to take effect

​
Option 2: Single Page Installation

To add the tracker to a specific page:
  1. In the Designer, navigate to the page you want to track
  2. Open Pages panel (press P or click the pages icon)
  3. Click the settings icon next to the page name
  4. Scroll to the Custom Code section
  5. Under Head Code, paste the CustomerOS tracker script
  6. Click Save
  7. Publish your site for the changes to take effect
For most use cases, we recommend site-wide installation to track visitors across all pages of your website.

​
Verifying Installation

After adding the tracker script and publishing your site:
  1. Visit your Webflow site
  2. Open your browser’s developer console (F12 or right-click → Inspect)
  3. Check the Network tab for a request to your tracker domain
  4. Look for successful 200s and 202s from the tracker subdomain
  5. Check the Console tab for any errors
You should see page views appearing in your CustomerOS dashboard within a few minutes.
We automatically handle capturing information from form submissions in Webflow, you don’t need to do anything differently to capture this signal!

​
Troubleshooting

If the tracker isn’t working:
  • Ensure you’ve published your site (the tracker won’t work in the Designer preview)
  • Check that your tracker domain is correct and accessible
  • Verify that the script is in the Head Code section (not Footer Code)
  • Check the browser console for any JavaScript errors
  • If using Webflow hosting, ensure your custom code is enabled on your plan
