Invoice and part payment

When shopping with Klarna invoice, the customer always gets their goods before they pay. We just need the customer's top of mind information to place the order, most of which they have likely already provided to you before they select how to pay.

How to integrate

Integrating Klarna's payment methods in your checkout requires only three simple steps:

  1. Prepare your checkout - collect customer details and present Klarna and a buy button in your checkout
  2. Initialize the API (Note: before creating the order you'll need a test account)
  3. Reserve the amount by calling our servers

Using our order management API, available in multiple SDKs, you can then update & cancel orders before fulfillment, activate the invoice to capture the funds, handle refunds, re-send invoice and check order statuses to manage your service center operations.
