Parameters

Name	Type	Description
locale	named optional String?	A string representing the user locale.
clientId	String	The client_id for your application.
scope	String	A space-delimited list of scopes that identify the resources that your application could access on the user's behalf. These values define the consent screen that Klarna displays to the user.
redirectUri	String	The “location” where the OAuth server redirects the user after the user completes the authorization flow. The value must exactly match one of the redirect_url values provided to Klarna in advance.
state	named optional String?	A string value that your application uses to maintain state between your authorization request and the authorization server's response. The Authorization server returns the exact value that you send to the redirect_url as a URL parameter.
loginHint	named optional String?	If your application knows which user is trying to authenticate, it can use this parameter to provide a hint to the Klarna’s Authorization Server. The server uses the hint to simplify the login flow by prefilling the email field in the sign-in form. It’s recommended to use this as it will improve the customer experience.
responseType	named optional String?	The desired grant type. The value MUST be one of "code" for requesting an authorization code or "token" for requesting an access token (implicit grant). The default is "code"
