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>Add a code plugin
In WordPress admin go to Plugins → Add New and install a header and footer code plugin such as WPCode, or use your theme's footer scripts setting.
Paste in the footer
Paste the snippet into the footer (before </body>) section and save.
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 on WordPress and WooCommerce
WordPress and WooCommerce sites install LiveCart with the code snippet. The simplest route is a header-and-footer code plugin, which survives theme changes.
