Connect Klarna

How Klarna signs requests

An API key in the Authorization header, written as Basic followed by the key.

Can you connect it today?

Yes. Add an API-key-in-a-header credential with the header name Authorization and the value Basic, a space, then your API key.

A sample mapping

Your application sends the first request below. The mapping turns it into the body of POST /payments/v1/sessions, shown second.

{
    "country": "SE",
    "currency": "SEK",
    "locale": "sv-SE",
    "total": 10000,
    "lines": [
        {
            "name": "T-shirt",
            "quantity": 1,
            "unitPrice": 10000,
            "total": 10000
        }
    ]
}

{

What you bring

This is not a ready-made connector. You bring a sample request or Klarna’s OpenAPI document, you or your agent write the mapping, and we run the integration you define.
