Create a Web channel
In the LiveCart console open Channels, add a Web channel, list the domains the widget may load on, and choose the AI agent that should answer.
Copy your snippet
Open the channel's Install tab and copy the code snippet. It already contains your public installation key and endpoints; the values below are placeholders.
<script async src="YOUR_SCRIPT_URL/livecart.js" data-livecart-key="YOUR_PUBLIC_KEY" data-livecart-endpoint="YOUR_API_ENDPOINT" data-livecart-render-mode="iframe"></script>Create a Custom HTML tag
In GTM, go to Tags → New → Tag configuration → Custom HTML, and paste the snippet.
Trigger on all pages
Set the trigger to All Pages (or a subset), save, then Submit and Publish the container.
Test it
Open your site in a private window, start a chat and ask a question your knowledge base covers. The conversation appears in your LiveCart inbox.
Install with Google Tag Manager
If your site already loads Google Tag Manager, you can install LiveCart without touching your theme, and roll it back from GTM.
