ProductReview uses Amazon’s Product Advertising API 5 (PA-API 5) — the same API behind the Amazon Creators programme — to fetch live product data. You connect it once.
What you need
- An approved Amazon Associates account for the marketplace you target (amazon.com, .co.uk, .de, …).
- PA-API access on that account. Amazon grants it once you’ve made a few qualifying sales; new accounts may need to generate those first.
Get your keys
- Sign in to Amazon Associates.
- Open Tools → Product Advertising API.
- Click Manage Credentials and Add credentials. Amazon shows an Access Key and a Secret Key — the Secret Key is shown only once, so copy it now.
- Note your Associate/Store ID (your tracking tag, e.g.
yoursite-20).
Enter them in the plugin
- Go to Product Review → Amazon API.
- Choose your marketplace/country.
- Paste the Access Key, Secret Key and Associate Tag.
- Save. The API status indicator turns green once a test call succeeds.
Not turning green? New keys can take a few hours to activate on Amazon’s side, and your Associate Tag must belong to the same marketplace you selected. See Amazon API error codes.
Marketplace & tag must match
A -20 tag is US-only; -21 is UK, and so on. If the country and tag disagree, Amazon rejects the call. Set one marketplace per site unless you use the plugin’s geo-targeting.
