Answers to the most common questions about review verification, Stripe integration, and how Signed Reviews works.
What is a purchase-verified review?
A purchase-verified review is a customer review that is cryptographically linked to a completed payment transaction. Signed Reviews connects to your Stripe account and only allows reviews from customers who have actually purchased from you, making every review tamper-evident and provably authentic.
How does Signed Reviews verify reviews?
Signed Reviews links each review to a completed Stripe transaction. When a customer submits a review, the platform verifies the purchase against your Stripe account and cryptographically signs the review, creating a tamper-evident record that proves the reviewer is a real customer and that the review has not been altered.
How is Signed Reviews different from Trustpilot?
Unlike Trustpilot, which allows anyone to write a review without verifying a purchase, Signed Reviews requires a completed Stripe transaction before a review can be submitted. This means every review on Signed Reviews is backed by proof of purchase, eliminating fake reviews by design. Trustpilot removed 2.7 million fake reviews in 2022 alone — Signed Reviews prevents them from being written in the first place.
Do I need to share my Stripe API keys?
No. Signed Reviews uses Stripe's official OAuth integration, which means you grant minimal permissions with one click — no API keys to copy, paste, or store. We can never charge, refund, or move funds, and we never change your customers, subscriptions, or prices. The only thing we can ever create is a discount coupon for a reviewer, and only when you enable review incentives.
Can customers leave reviews without a purchase?
No. Every review requires a verified purchase. A review link is issued in one of two ways: automatically after a Stripe charge succeeds (emailed to the customer's verified email from the transaction), or on request — a customer can visit the business's public page and enter their checkout email to receive their own link. In both cases, the email must match a real completed purchase on the business's Stripe account. Without a matching purchase, no link is issued and no review can be submitted.
What happens if a charge is refunded?
If a charge is refunded, the associated review is automatically hidden from your public page and API responses. The cryptographic signature remains valid — proving the review was authentic — but the content is no longer displayed. This keeps your review feed accurate while preserving the integrity of the verification system.
How long are review invitation links valid?
Review links are valid for 14 days on every plan. After expiry, the link can no longer be used to submit a review. A new charge (or a fresh self-service request) generates a new invitation.
Can I customize the review request emails?
Yes. You can customize your logo, content alignment, and logo size from the dashboard. The email subject line reflects your business name. Review reminder emails follow the same template with a slightly different subject and lead sentence so they don't feel like duplicates.
Does Signed Reviews work with Shopify, WooCommerce, or Squarespace?
Yes. Signed Reviews is a Stripe App, so it installs in one click and connects to your Stripe account — including accounts that Shopify, WooCommerce, or Squarespace manage on your behalf. If your checkout runs on Stripe, your reviews can be verified, with no separate plugin required.
Is Signed Reviews free?
There is a free plan for self-service collection, forever. Paid plans from $29/mo add automation, reminders, webhooks, and higher volume. See our pricing page for the tiers.
