Most Amazon affiliate plugins display products you already know about. You pick ASINs, embed them, and hope visitors buy those exact products. But what about everything else your visitors want? They leave your site, search Amazon directly, and someone else gets the commission.

Paapi Product Search for Amazon changes that. It adds live Amazon product search to your WordPress site. Visitors search, filter, browse, and click through to buy – every product automatically tagged with your Associate ID. You earn commissions on whatever they decide to buy, not just the products you manually linked.

One shortcode. No ASIN hunting. Works in minutes.

Works with both the Creators API (Amazon’s newer OAuth 2.0 product API) and PA-API v5 (the Product Advertising API), so your site keeps earning through Amazon’s API transitions. Pick the auth method you already have approved, or switch between them without rebuilding your pages.

Why Affiliates Use It

Earn on every search, not just manual links – visitors discover products you never had to curate
Keep visitors on your site – interactive search reduces bounce rates
Fast by default – build-time server-side rendering (SSR) means instant page loads
Smart caching – search results cached 30 min, product data cached 1 hr, so your API quota stays healthy
Works with both APIs – Amazon Creators API (OAuth 2.0) and PA-API 5.0 (AWS Sig V4)
