The Klarna Ecom API aggregates product data, pricing, reviews, and deals from multiple top e-commerce platforms through Klarna’s shopping ecosystem. With a single API, you can access data from stores including Amazon, Walmart, Best Buy, Target, and many more, across 13 supported regions.
What the API Covers
Multi-store product search is the core capability. A single query returns results from multiple retailers, making it practical for building comparison engines, deal finders, or shopping aggregators without managing separate API integrations per store.
Price history is available at the product level with data across multiple time intervals. This makes it possible to build price trackers, alert systems, or discount pattern analysis tools without maintaining your own historical pricing database.
Product reviews include both user-submitted ratings and written reviews, as well as professional review content where available. Related product groups are accessible alongside the main product data, useful for building “similar items” or “frequently compared” features.
Category and store intelligence endpoints expose the full structure of Klarna’s shopping ecosystem: store lists, category hierarchies, subcategories, cashback opportunities, and curated Klarna shopping experiences. This is the data layer needed for building structured navigation and browsing interfaces.
Deal discovery surfaces currently discounted products and active deals across the ecosystem.
Supported Regions
The API supports 13 regions: Austria, Denmark, Finland, France, Germany, Ireland, Italy, Netherlands, Norway, Spain, Sweden, UK, and USA. All features are supported across all regions. Pass the region parameter to localize results; the default is usa.
