Use one of these script configurations: ```html theme={null} ``` ## Verification 1. Open your website, then open the browser console and run: * `window._cms` 2. Visit a test landing page URL that includes `cms_rf`, for example: * `https://your-site.com/?cms_rf=test` 3. Confirm a first‑party cookie is set (in your browser devtools under **Application → Cookies**). If the checks fail, make sure: * The script is present in the `` and not duplicated. * Your site (or CDN) is not serving a cached version of the page missing the script. ## Next steps After the script is installed, you can send **Lead** and **Sale** conversions from your backend (recommended) using the Attribution endpoints.
