Shopify

On a page

In the theme editor, add a Custom Liquid section (or a custom HTML section, depending on your theme) where you want the widget, and paste:

<script src="https://rentx.al/embed.js" data-rentx-partner="your-partner-id"></script>

Save and view the storefront — the theme editor’s preview does not always run embedded scripts.

In the theme code

If your theme has no suitable section, edit the template directly (Edit code) and paste the tag into the template where the widget belongs — not into theme.liquid’s <head>, which renders it nowhere visible.

A note on checkout

The widget hands visitors to RentX to book and pay. It is not a Shopify product and does not go through your checkout, so put it where that makes sense — a landing page, a blog post, a sidebar — rather than in a cart or checkout flow.
