Check the details of a payment session

Use the Klarna payments API to check the details of a session at any time.

To see the details of the session created when initiating a payment, send a GET request with an empty request body to the {apiUrl}/payments/v1/sessions/{session_id} endpoint. Provide the id of the session you want to revise as a session_id path parameter.

We only share customer details after authorizing the session.
