You’ll need to embed Hi Touch in the global theme file in your Shopify theme. This is so the script is available on every page within the store to keep the Hi Touch session running while users are navigating the site.
In the Shopify Admin in the sidebar go to Online Store > Themes. Then on the right, locate your current theme and click on Actions > Edit Code.
In the template editor, and at the top of the template files column, locate theme.liquid.
Open this file and locate the closing </head> tag. Just before it, add a line break and paste the following script. Before you do, be sure to replace the part _CHATSPACE_TOKEN_ with the ID token given to you.
<!-- Hi Touch Embed Code -->
<script crossorigin="anonymous" async="" src="https://embed.gethitouch.com/v1/script.js?token=_CHATSPACE_TOKEN_&session-param-name=sessionId"></script>
Save this file.
You should now be able to conduct Hi Touch sessions on your website.
