Webflow's Project Settings → Custom Code lets you inject scripts into every page's <head> globally — no per-page editing required.
After signing up, copy your API key from your Findables dashboard.
In the Webflow Designer, click the W logo (top left) → Project Settings → Custom Code tab.
In the Head Code field, paste the following:
Replace YOUR_API_KEY with your API key and YOUR_SITE_SLUG with your site slug — both are in your dashboard.
Click Save Changes, then publish your site. The script will be included on every published page.
View source on any page to confirm — you should see the Findables script tag in <head>.
