I'm integrating a Sweden API into my app.

API: Klarna ~ payments & buy-now-pay-later API
Provider: Klarna
Auth: requires an API key (sign up: https://docs.klarna.com/)
Pricing: paid
Base URL: https://api.klarna.com/
Important note: Swedish fintech; region-specific base URLs and a playground environment, requires merchant credentials (Merchant ID + API credential).

Source: Klarna (https://docs.klarna.com/)
Source type: Provider API or developer docs
Endpoint type: Provider API base URL
Integration difficulty: Needs API key
Last checked: 2026-07-05
Production caveat: Keep credentials server-side and confirm current limits, pricing, and webhook/error behaviour in the provider docs.

Help me set up the correct onboarding/authentication path and make the first valid request ~ explain exactly where credentials go and what must happen before production.
