[DEPRECATED] Official Klarna .NET Core SDK

SDK Deprecation Warning and Sunsetting

Dear community, the SDK you are currently looking at is now deprecated. These are details related to sunsetting:

• We intend to archive this repo on June 1 2020 (01/06/20)
• Until November 1 2020 (01/11/20) high severity security issues found within the latest published version will be fixed. All support will cease after this date.
• No new builds will follow effective April 20 (20/04/2020) apart from the fixes mentioned above.

Workarounds

We are making Klarna REST API definition files available in Swagger / OAS v2 format, under the Klarna API Reference section on the Klarna Developer Portal. These will be regularly updated as the APIs evolve. You can use tools like https://swagger.io/tools/swagger-codegen/ to generate your own SDKs, client libraries, etc.
