How to add testimonials to Kartra

Whether you use Kartra's Page Builder, Checkout pages, or Kartra Mail, you can embed a self-updating testimonial wall with just two lines of HTML. No plugins, no monthly fees, no manual updates.

The universal snippet

This works on any Kartra page. Copy your space ID from your Vouchnest dashboard, replace YOUR_SPACE_ID, and paste both lines into any Custom HTML box on your Kartra page.

HTML snippet

<script src="https://cdn.vouchnest.com/widget.js" data-space-id="YOUR_SPACE_ID" async></script>
<div id="vouchnest-wall"></div>

Self-updating

Approve a testimonial in your dashboard — it appears on the wall automatically. No redeploy needed.

Responsive

The wall adapts to any container width. Works on desktop, tablet, and mobile out of the box.

Fast-loading

The widget script is small and loads asynchronously — it won't block your page render.

No code? Use the hosted wall page

Every Vouchnest space gets a hosted wall page at vouchnest.com/wall/your-space-slug. Link to it from your Kartra menu, a button, or your footer. No HTML embedding needed — just paste the URL. It’s fully public and updates automatically.
