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}]{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.
If the session id in your request is invalid, you get an error response. Ensure the session_id value you provided is correctly formatted and corresponds to a session that has not expired.
