In the Payrails Portal, go to Settings → Integrations, open your Stripe integration, select Klarna under Payment methods, and save.
Add Klarna as a payment option in your workflow.

  },
  "paymentComposition": [
    {
      "integrationType": "hpp",
      "paymentMethodCode": "klarna",
      "amount": {
        "value": "109.90",
        "currency": "EUR"
      }
    }
  ],
  "meta": {
    "order": {
      "billingAddress": {
        "name": "Anna",
        "lastName": "Becker",
        "email": "anna.becker@example.com",
        "country": {
          "code": "DE"
        }
      }
    }
  },
  "returnInfo": {
    "success": "https://example.com/success",
    "error": "https://example.com/error"
  }
}

After the customer confirms the purchase, Klarna returns them to your success or error URL. Confirm the result through webhook notifications or the execution status before you fulfill the order.

How Stripe handles Klarna

With delayed capture, Payrails creates the Stripe payment with manual capture, so you capture or cancel it later. With instant capture, Stripe captures the payment when the customer confirms it.
Send an amount greater than zero.
Each Klarna payment is a new customer-initiated payment.
