Klarna Docs - Create a Klarna Customer Token

Create a Klarna Customer Token

Creating a Klarna Customer Token results in Klarna storing customer and payment method details. You can later used the token_id shared with you to trigger purchases for the Klarna customer token.

After having obtained an authorization_token for a successful authorization, this can be used to create a purchase token instead of placing the order.

Since a purchase token has no order lines and amount connected to it, there is no need to charge the customer at this point. Instead the purchase token will be used to charge consumer at a later stage, which can be read in a separate article.
