Multi-Region API

A multi-region API serves data covering multiple geographic markets through a single integration, with a parameter to specify the target region. This allows a developer to power applications targeting users in different countries without maintaining separate integrations per region.

The Klarna Ecom API supports 13 regions (Austria, Denmark, Finland, France, Germany, Ireland, Italy, Netherlands, Norway, Spain, Sweden, UK, USA) via a single region parameter. A single integration can power a global price comparison tool without any additional development per market.

Multi-region APIs save significant development time for applications with international scope. When evaluating them, verify whether all features and data fields are available across all regions or whether coverage varies by market.
