One-time payment order

Creating an order differs for one-time and recurring payments. For one-time, send a POST with authorization token to Klarna. For recurring, generate a customer token first.

The process of creating an order is different for one-time and recurring payments.

For one-time payments, get the authorization token ready and send a request to Klarna API
For recurring payments, generate a customer token prior to placing the order

Create an order

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.

A POST request to create an order for a one-time payment.

Success response

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 API
redirect_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 payment
fraud_status, an indicator of whether the transaction is suspected to be legitimate or fraudulent
authorized_payment_method, the payment method selected by your customer for this purchase

"fraud_status": "ACCEPTED",
"authorized_payment_method": "invoice"
}

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.

Error response

If your request doesn't pass our validation, you'll receive an error response. The most common reasons why creating an order fails are:

placing the order more than 60 minutes after authorization
modifying purchase details after authorization without updating the payment session

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.

Special considerations for one-time payments

Automatic capture of created orders

If your Klarna contract allows automatic capture of the order once an order is created, set auto_capture to true when creating the order.

Recurring payment order

For recurring payments, you have to create a customer token before placing the order. This token identifies your customer and the payment method selected for the purchase. It also lets you charge the customer later, ad-hoc or at regular intervals.

For payments where you charge the customer at checkout and enable a recurring charge (intent set to buy_and_tokenize), you have to send two separate create order requests:

1.
In the first request, use authorization_token to charge the customer at checkout.
2.
In the second request, use customer_token for future recurring payments.

If you're not charging the customer at checkout (intent set to tokenize), you need to send only the second request to place the order and charge the customer at a later date.

If you're creating an order related to a subscription, include the subscription object in your create order request. Learn more about sharing subscription details with Klarna.

Create a customer token

Request a customer token by sending a POST request to the {apiUrl}/payments/v1/authorizations/{authorizationToken}/customer-token endpoint.

Include the authorization token from the authorize() call as the authorizationToken path parameter.

A POST request to create a customer token for a customer located in the US.

Success response

In response to the customer token request, Klarna sends:

token_id, a customer token identifier that you later use to create an order
redirect_url, a URL to which the customer is redirected after the order is placed
