Requesting the release

Use the Klarna payments API to cancel an authorization and remove any customer debts gotten during the payment session.

When a customer won't complete a purchase or you won't use the authorization token immediately, you can cancel the authorization. This action clears the customer's debt.

To cancel an authorization, send a DELETE request with an empty request body to the {apiUrl}/payments/v1/authorizations/{authorizationToken} endpoint. Provide the authorization token you got from the authorize() call as an {authorizationToken} parameter.

Canceling an authorization might impact our credit assessment when attempting to generate a new one.

In response to your call, you receive a 204 status code corresponding to a successful but empty response.
