Other supported platforms
Wix, Squarespace, Webflow, BigCommerce, and Ecwid can load Flatzer through the HTML snippet without native plugins.
<script src="https://flatzer.com/widget.js" data-flatzer-widget="wgt_0123456789abcdef0123456789abcdef" async></script>Compatibility through embedded code
Wix, Squarespace, Webflow, BigCommerce, and Ecwid accept custom code in pages or templates. Add the official snippet in the global area closest to the closing body tag so that it loads once.
Check your plan rules
Flatzer does not provide a native plugin for these platforms. Some plans restrict global scripts or checkout pages, so review your provider documentation and verify a normal public page.
