Webweezl Reviews. Shopify reviews app — Amazon stars + GDPR-native.
A Shopify app that bundles your Amazon star ratings (via the official Creators API) and your first-party customer reviews in a single surface — with GDPR-compliant moderation, hosted in Germany, embedded inside your Shopify Admin.
Four breaks between reviews and trust.
Sell hard on Amazon and you build up a mountain of star ratings there. On your own Shopify storefront, none of that shows. Here are four gaps European merchants regularly miss between Amazon trust and their own product pages.
4.7 stars on Amazon — 0 stars on your own site.
A product with 4.7 stars from 240 reviews on Amazon. On your Shopify page: no visible reviews at all. Buyers who came to you instead of Amazon see an empty storefront — and switch back. That's trust you've poured into a platform you're not bringing with you.
Yotpo, Loox, Stamped — all on US cloud.
The big Shopify review apps run on US hosting (often AWS). If you operate under strict GDPR — say because you sell in regulated industries (pharma-adjacent D2C, B2B compliance, premium brands) — US hosting for customer reviews is a direct sub-processor risk on your data-protection register.
Reviews come in — and nobody qualifies them.
Standard apps either offer no moderation or a binary "approve/reject" toggle. For GDPR-compliant data processing you need clear audit logs (who moderated, when, why), deletion workflows, anonymization options — and most US tools simply don't provide that.
Scraping Amazon reviews isn't an option.
If you want to show Amazon stars on your own site, you can't just scrape them — that violates Amazon's terms and is GDPR-questionable on the legal side. You need the official Amazon Creators API with proper auth — setup work most Shopify apps shy away from.
What you actually get.
Webweezl Reviews is three disciplines in one stack: Amazon-stars sync (via the official Creators API), first-party review system with GDPR moderation, and Shopify theme integration with native Polaris widgets.
Through the official Amazon Creators API, your Amazon star rating, review count and distribution mirror directly onto your Shopify product page — GDPR-compliant, with proper API auth, no scraping.
Star rating with review count is mirrored per product — directly under the product title or wherever your theme allows. Configurable per product: show or hide, override option for manually verified data.
Full star distribution (X% 5-star, Y% 4-star, etc.) like on Amazon. Helps buyers judge beyond the average rating. Activatable per product.
Automatic sync of Amazon data (daily by default, configurable per plan). Incremental updates, no full re-scrape per sync. Manual trigger available in admin.
Plus a complete first-party review system for buyers who ordered directly from you — with a GDPR moderation workflow and Polaris-compliant admin interface.
After order (configurable: 7/14/30 day delay) automatic email to the buyer with a review request. Customizable templates, multi-locale (DE/EN). Anti-spam: only to verified buyers.
Incoming reviews go through a moderation queue. Four actions: approve, reject, anonymize (name → “Verified buyer”), delete. Every action with audit log: who moderated, when, why (optional reason). Retention configurable.
App runs embedded inside Shopify Admin, with native Polaris design (Shopify's design system). Feels like a part of Shopify, not an external tool.
Reviews need to surface — on product pages, on category overviews, on the homepage. Integrated via theme apps and Liquid tags.
Reviews as native Shopify theme app blocks. Theme editor: drag-and-drop into product page, category page, homepage. Works with Online Store 2.0 themes.
For themes without app-block support: Liquid tags and custom JS embeds. Works in any Shopify theme, including legacy. Full control over position and styling.
Review widgets in the correct language of the storefront locale. DE and EN out of the box, additional languages via locale files. Customizable strings for “Write a review”, “Stars”, etc.
Reviews live on German soil.
Most Shopify review apps run on US cloud (often AWS). Webweezl Reviews is explicitly Hetzner-Germany-deployed — database, app server, backups, all in DACH. That isn't "GDPR-compliant too" as a marketing claim, it's an architecture decision.
Hosting at Hetzner Falkenstein/Nürnberg. Database (PostgreSQL via Prisma), app server (React Router v7 in production mode), backups — fully EU-hosted. ISO 27001, standard data-processing agreement with Hetzner as processor. Sub-processor list is short: Hetzner, Shopify itself, Amazon (for Creators API). That's it.
Moderation audit log. Every moderation action (approve/reject/anonymize/delete) is stored with an audit log entry: who, when, why. 7 years retention by default (the GDPR-aligned marketing-consent retention window). The anonymize action replaces reviewer names with "Verified buyer" — irreversible, with an audit trail.
For European merchants in regulated or reputation-sensitive industries (premium D2C, B2B sales, pharma-adjacent e-commerce) this architecture is the only one that holds up under audit. Clean sub-processor list, documented moderation, EU hosting end-to-end.

Who uses Webweezl Reviews to its full potential.
Built for European Shopify merchants who want to bring their Amazon trust onto their own storefront — and care enough about GDPR + EU hosting that a US tool isn't an option.
European D2C with strong Amazon portfolio
You sell on Amazon DE/EU and have 50–500 products with thousands of reviews. On your Shopify shop: empty product pages with no trust signals. Reviews mirrors Amazon stars with proper API auth — no scraping tricks.
▶ Conversion rate on Shopify lifted without building reviews from zeroPremium brands with GDPR focus
Premium brands in pharma-adjacent D2C, B2B sales, beauty with ingredient compliance — you need documented moderation and EU hosting for your customer reviews. US tools like Yotpo or Loox don't fit your sub-processor list.
▶ Reviews solution that holds up in a GDPR auditMulti-channel merchants (Amazon + Shopify)
You sell the same catalog on Amazon and on your own Shopify shop. Today: two separate review universes. Reviews bundles both — Amazon stars + first-party D2C reviews in one widget — and gives buyers the full picture.
▶ One trust view instead of two isolated review universesGrowing Shopify shops with new products
You launch new products regularly — they have no reviews initially. If the product is also on Amazon (even from other sellers of the same item), you can use the Amazon reviews as initial trust until your own review volume catches up.
▶ Cold-start problem for new products solvedDemo and tailored setup — we agree it based on your use case.
Webweezl Reviews is set up together — app configuration, Amazon sync, theme integration and GDPR workflow look different per shop. Pricing and setup plan get clarified in the first call, based on your specific use case.

The questions that come up again and again in first-call conversations about Reviews setups.
-
01 How is Webweezl Reviews different from Yotpo, Loox or Stamped? +
Three differences: (1) Hetzner Germany hosting instead of US cloud — relevant for GDPR-strict industries. (2) Amazon star ratings via the official Creators API — no scraping tricks, terms-of-service compliant. (3) GDPR moderation workflow with audit log — every moderation action is documented (who/when/why), plus an anonymization function for Article 17 (right to erasure) requests.
-
02 Does the app work with my Shopify theme? +
Yes — three paths: (a) Native theme app blocks for Online Store 2.0 themes (Dawn, Refresh, etc.) via drag-and-drop. (b) Liquid tags for vintage themes or custom setups. (c) Custom JS embed for full position control.
-
03 How does the Amazon sync work? +
Via the official Amazon Creators API. You authenticate once with your Amazon account, pick the matching ASIN per Shopify product (manually or via CSV import), and the app syncs your stars, review count and rating distribution. Sync frequency is tier-dependent (daily on higher plans).
-
04 What if I'm not an Amazon seller? +
Then you use the app for first-party customer reviews only. Post-purchase emails, moderation workflow, storefront integration — all of that works without the Amazon component. The Amazon-stars piece is optional.
-
05 What does GDPR compliance look like in practice? +
Three layers: (1) Hosting at Hetzner Germany (ISO 27001, standard data-processing agreement). (2) Moderation audit log — every action documented. (3) Anonymization workflow — reviewer name can be replaced with "Verified buyer" for Article 17 requests. DPA available as PDF, sub-processor list transparent.
-
06 Can I migrate reviews if I'm coming from Yotpo or Loox? +
Yes. CSV import of existing reviews (with original date, reviewer name, star rating, review text). We work through it together during onboarding — usually 1–2 hours of work for 1,000–10,000 historical reviews.
-
07 What about spam and fake reviews? +
Three layers: (a) Post-purchase emails go only to verified buyers (not arbitrary visitors). (b) Moderation queue for every review before publication. (c) Audit log for retroactive spam-cleanup actions. Bot protection at the form-submission level (honeypot + timing).
-
08 How does it look on the storefront? +
Embedded star widget under the product title or wherever your theme allows. Optional: distribution bar (5/4/3/2/1 star breakdown). Reviews list on the product page with sort and filter. Fully responsive, in Shopify's Polaris design or adaptable to your theme.
-
09 Do I get support if something breaks? +
Yes — direct with Webweezl, no anonymous support-ticket system. Email support during business hours, faster response on emergencies. Onboarding setup support included.
