Server-side authorization callback for Klarna Payments. Configured as
`merchant_urls.authorization` on the Payments session. Klarna POSTs the
`authorization_token` and `session_id` so the merchant can place the
order even if the front-end loses the token (for example after a bank
app switch).
Delivered after Klarna Payments authorizes a session.

About AsyncAPI
The AsyncAPI specification describes event-driven APIs the way OpenAPI describes request/response APIs. A channel is the named pipe — a webhook URL, a Kafka topic, a WebSocket route, an MQTT subject — that producers and consumers publish or subscribe to. Each channel carries one or more messages with structured payloads, and an operation declares whether a given party sends or receives on that channel.
Discovery needs no key. Ratings and market analysis are Pro.
