Step-by-step guide to add OnyxMetric cookieless analytics to your Drupal site and start tracking visitors

On Drupal you add the tag by editing a theme template. Drupal's page cache serves stored HTML, so clear caches after any change.

In OnyxMetric, open your site's Site Settings and copy the tracking script. It looks like this:

<script src="https://app.onyxmetric.com/api/script.js?siteId=YOUR_SITE_ID" async></script>

YOUR_SITE_ID is the numeric ID of your site.

Copy core/modules/system/templates/html.html.twig into your theme's templates folder if it is not there yet. Add the tag just before </head>:

themes/custom/mytheme/templates/html.html.twig

<script src="https://app.onyxmetric.com/api/script.js?siteId=YOUR_SITE_ID" async></script>
</head>

Clear caches afterwards so Drupal picks up the new template:

drush cr

You can also use Configuration → Development → Performance → Clear all caches.

Load your live site and click through a few pages. Pageviews show up in the OnyxMetric dashboard within seconds.

If nothing arrives:

View the page source and search for script.js?siteId= to confirm the tag is present.
In the browser's Network tab, check that script.js returns 200 and that requests go to /api/track.
Turn off ad blockers, or proxy the script through your own domain.
Read script troubleshooting for other causes.

Troubleshooting

Tag missing after the change: pages are served from Drupal's page cache. Clear all caches and reload.
Tracked on some pages only: a content type or region may use a different template. Check which html.html.twig variant renders those pages.
Admin pages: if your admin theme has its own html.html.twig, it does not load the tag unless you add it there. That is usually what you want.
