ProofWall field notes

Add Testimonials to Thinkific: Free Widget

Install a ProofWall wall on Thinkific. Specific editor steps, the right embed snippet, and common publishing pitfalls.

A site-builder text-and-media section may expose source HTML for embeds.

Before you paste

Create a wall, share the collection link, and approve your first testimonial. Copy the slug from the Embed tab. Instructions reflect editor patterns from 2025–2026; menus and plan support vary.

Installation steps

Open Site Builder and select the course landing page.
Use an HTML-capable section or custom section for the iframe snippet.
Publish and check the actual page at mobile width.

Your embed snippet

Replace YOURSLUG with the slug shown in your dashboard.

<iframe src="https://proofwall.wouldairecommend.workers.dev/w/YOURSLUG?embed=1" title="Customer testimonials" width="100%" height="700" style="border:0" loading="lazy"></iframe>

Watch out for

HTML sanitisation depends on the section and theme. When iframe markup is removed, use a hosted wall link rather than modifying checkout or relying on unsupported scripts.

Check before sharing

Open the published page at desktop width and at 360 pixels. Confirm that quotes are readable, links work, and an iframe has enough height. Check both light and dark themes. Never put your private account access link in an embed.

Questions, answered

Can I paste a script into Thinkific?

This guide uses an iframe to avoid relying on parent-page script execution. Check your editor’s supported embed block.

Why is my widget empty?

Approve a testimonial first. Replace YOURSLUG with your wall’s eight-character slug. Check browser network and content-security-policy errors, then try the hosted wall URL.
