# Adds support for saving Klarna payment methods ## What’s new Adds support for saving Klarna payment methods and charging them later with the customer either off-session or on-session. This feature is available both through [Stripe Billing](https://docs.stripe.com/billing.md) and through a direct integration with the *Payment Intents API* (The Payment Intents API tracks the lifecycle of a customer checkout flow and triggers additional authentication steps when required by regulatory mandates, custom Radar fraud rules, or redirect-based payment methods) using `setup_future_usage` or the *Setup Intents API* (The Setup Intents API lets you build dynamic flows for collecting payment method details for future payments. It tracks the lifecycle of a payment setup flow and can trigger additional authentication steps if required by law or by the payment method). ## Impact You can now save Klarna payment methods and charge them later. Use this feature to: - Set up and charge subscriptions automatically, either through Stripe Billing or through a direct API integration - Sell a physical product and set up a subscription at the same time - Let your customer save their payment method for faster *on-demand* (When a customer stores their payment method with a business, they can make on-demand future purchases without re-authenticating, such as ordering a ride in their ride-share app) payments ## Changes #### REST API | Parameters | Change | Resources or endpoints | | --------------- | ------ |
