Once Klarna authorizes the purchase, use the authorization token to create an order and complete the one-time payment.
To create an order for a one-time payment, send a POST request to the {apiUrl}/payments/v1/authorizations/{authorizationToken}/order endpoint and include authorization_token in the path.
For example, if the authorization_token is b4bd3423-24e3, send your request to the {apiUrl}/payments/v1/authorizations/b4bd3423-24e3/order endpoint.

When you receive a success response, the customer gets charged and the Klarna payments session is closed.
As part of the response, you receive the following details:
order_id, an order identifier that you can later use to capture or refund the order using the Order management APIredirect_url, a URL to which you redirect the customer. This isn't included in the response received if you didn't include the URL when initiating a paymentfraud_status, an indicator of whether the transaction is suspected to be legitimate or fraudulentauthorized_payment_method, the payment method selected by your customer for this purchase{

}A success response to the order creation request for a one-time payment.
Send the customer browser to redirect_url provided in the response. Klarna places a cookie in the browser and redirects the customer back to the confirmation URL you provided when creating the session. This makes the checkout faster the next time the customer chooses to pay with Klarna.
If your request doesn't pass our validation, you'll receive an error response. The most common reasons why creating an order fails are:

"error_code": "ERROR_CODE",
"error_messages": [
"ERROR_MESSAGE"
]
}An error response to the order creation request for a one-time payment.
Here are examples of common errors with troubleshooting suggestions. You can use the value in correlation_id to find entries related to the request under Logs in the Merchant portal.
| Error code | Error message | Description |
|---|---|---|
NOT_FOUND | Invalid authorization token | The authorization token has expired because the order was placed more than 60 minutes after authorization. To fix the error, request a new authorization_token and use it to place the order. |
BAD_VALUE | Not matching fields: [billing_address.postal_code] | The data shared with Klarna in a previous step (create_session, load(), or authorize()) have been modified causing the validation to fail. |
BAD_VALUE | Not matching fields: [Incorrect number of items in the cart. Expected: 2, Actual: 3] | The order lines or the cart were updated after the authorize() call. Please ensure that the cart is kept as-is or send a new authorization request. |
REJECTED | Rejected | This is an edge case reason, but can be triggered in case the merchant is configured with being allowed to update the cart. This could be updated from the authorize to the place order in such a way that a new authorize is triggered. In this case this is rejected. |
If your agreement with Klarna allows it, we can flag a suspicious transaction for an additional review instead of accepting it immediately. In such cases, fraud_status in the response will be PENDING instead of ACCEPTED. Read more about pending orders.
