Klarna Payments integration for Maho Commerce.

This is a port of Klarna's Magento 1.x plugin to Maho, comprising three modules:

• Klarna_Core — shared REST client, request/order-line builders, abstract payment method, and the klarna/notification callback controller.
• Klarna_Payments — the customer-facing Klarna Payments method (checkout iframe, session create/update, authorization).
• Klarna_OrderManagement — post-purchase operations (capture, refund, cancel, extend authorization) via Klarna's Order Management API.

See https://developers.klarna.com/documentation/klarna-payments/

Requirements

• PHP >= 8.3
• Maho Commerce >= 26.5
• An account with Klarna

Disclaimer

The original Klarna Magento 1 plugins were offered as-is; with the deprecation of Magento 1, Klarna no longer maintains them. This Maho port is an independent effort and is likewise provided as-is. Klarna's API can change over time; the user assumes full responsibility for maintaining their store and its Klarna integration, including updating for API changes and security fixes.
