Testimonials
This feature has two independent parts:
- Testimonials block: a checkout extension that shows full customer review cards (name, stars, review text) on the checkout page.
- Ratings on upsells: shows star rating average and review count for each product inside upsell across checkout, thank you page, order status page, and post-purchase upsell.
Supported review apps: Judge.me, Okendo

How to set up
Section titled “How to set up”Testimonials block

Ratings on upsells
- Go to Testimonials in the app and select your review app (if not already done).

- Ratings on upsells pull from the same review app. No separate setup needed once the app is connected.
- Make sure your review app has collected reviews before enabling this feature.
Use cases
Section titled “Use cases”- Testimonials block: show a carousel of 2–3 reviews on the checkout page to reassure hesitant customers before they complete the order
- Ratings on checkout upsell: show star average and review count on the upsell product to make the add feel lower risk
- Ratings on thank you page / order status page upsell: reinforce the upsell offer with social proof when the customer is reviewing their order
- Ratings on post-purchase: validate the upsell product with reviews before the customer decides
Best practices
Section titled “Best practices”- Enable testimonials only after you have at least 5–10 reviews per product. A block with nothing to show is wasted space.
- Use Carousel mode for checkout upsells to keep it compact. Use Stacked for when there’s more space.
- Set Reviews per product to 3 maximum at checkout as customers are in a hurry and won’t read more.
- Position reviews below price in checkout upsells so the price is seen first, then validated by the review.
- Use testimonials alongside Trust Badges for maximum reassurance at checkout.
