API URLs

Kustom APIs are available through different base URLs relating to your location and interaction needs. To access these APIs, combine the base URL + endpoint, for example to "create an order" construct the URL to call like this: Base URL for environment + /payments/v1/authorizations/

Example url for Live environment

https://api.klarna.com/payments/v1/authorizations/

Use the testing environments to get familiarized with API behaviour and try out things; use the live environments to start real transactions with Kusto.

NOTE: Use HTTPS for all of your interactions with Kustom APIs.
