Raw HTML
Add the LinkToast widget to any HTML page with a script tag.

Drop the embed script into a Custom HTML block or your theme footer. WordPress outputs the tag on the front end and Studio handles widget updates.
Publish in Studio and copy the embed snippet from the Code button.
Edit the page, post, or template where the widget should live. The block editor and the classic editor both work.
Insert a Custom HTML block where you want the Trusted By section. Paste the embed snippet from Studio into the block. Do not wrap it in a shortcode unless your theme requires it.
Save and view the public page. For a site-wide footer embed, paste the same snippet into a footer widget area or your child theme footer template, then clear any page cache plugin.
Sign up, publish a widget, and paste the embed code on your site.
