No events on the webflow.io preview URL.

Custom Code Head runs only on published domains. Use your live custom domain, or set data-domain to yoursite.webflow.io if you want to test on the staging URL.

No events are showing up. What now?

Open DevTools Console and Network. Filter for script.js and /api/event. If they are blocked:csp, your Content Security Policy is blocking admaxxer.com — see /documentation/troubleshoot/csp. Also double-check that data-website-id matches the ID shown in your dashboard.

Events show up in staging but not production.

Confirm data-domain matches the production hostname exactly (no protocol, no trailing slash). Also confirm the website's Allowed Domains list in settings includes the prod domain.

My site is a single-page app — am I missing pageviews?

Use script.hash.js if you rely on location.hash routing. Otherwise the default script.js already hooks history.pushState/replaceState and tracks SPA navigations.

Install Admaxxer on Webflow

Project Settings → Custom Code → Head.

Webflow has a built-in slot for custom head code at the project level. Pasting the Admaxxer snippet there installs the pixel on every published page — no per-page edits.

Steps

1 Open Project Settings

In the Webflow Designer, click the site name (top-left) → Project Settings → Custom Code tab.
2 Paste the snippet into Webflow

In Webflow, navigate to the Head Code text area under Custom Code. Paste the snippet below and save. It must be in the site-wide <head> so it fires on every page.

html
```
<script defer
  data-website-id="YOUR_WEBSITE_ID"
  data-domain="yourdomain.com"
  src="https://cdn.admaxxer.com/js/script.js"></script>
```
3 Publish your site

Save the Custom Code panel and click Publish. Custom code only runs on published (not preview) domains.
4 Verify the install

Load any public page on your site in a fresh browser tab. Within a few seconds, the Admaxxer dashboard realtime view should show the event. If nothing lands after 2 minutes, re-check the snippet is actually in the rendered HTML <head> (View Source, not just DevTools).

Verify installation

Load any page on your domain in a normal browser tab.
In the Admaxxer dashboard, open Pixel → Realtime — a pageview should appear within ~5 seconds.
Or hit GET /api/pixel/healthcheck?website_id=YOUR_WEBSITE_ID — lastEventAt should be non-null.
