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/
https://api.kustom.co/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 Kustom.
NOTE: Use HTTPS for all of your interactions with Kustom APIs.

Important information
Klarna’s live API (https://api.klarna.com/) will remain functional alongside Kustom’s own API for an undefined transitional period.
The API endpoints supports the HTTP/1.1 and HTTP/2 protocol.
