When a customer completes their purchase with Klarna, Klarna authorizes the payment and sends the authorization back to your store. PrestaShop creates the order using the status you selected for new Klarna purchases during configuration.

Below is a high level overview of the post purchase lifecycle:

1. The purchase is authorized by Klarna.
2. You prepare the items for shipping.
3. You capture the payment, either automatically or manually.
4. Items are shipped to the customer.
5. You may issue full or partial refunds if needed.

Info: Klarna recommends managing all post purchase actions for Klarna purchases in PrestaShop instead of the Klarna Merchant Portal to keep both systems aligned.

Klarna module allows you to manage and see the order information. To see that you need to navigate to the Orders -> Orders page in the PrestaShop admin panel.

Each Klarna purchase contains a Klarna section in the PrestaShop order details page. This section displays:

• Klarna reference number
• Klarna payment status
• Actions available, such as capture or refund
• A link to view the purchase in the Klarna Merchant Portal
• A history of all Klarna related events

Klarna authorizes the payment during checkout, but the payment is not collected until you capture it. PrestaShop allows both automatic and manual captures based on your module settings.

To capture a payment manually:

1. Open the Klarna purchase in PrestaShop.
2. Go to the Klarna section.
3. Select Capture payment.
4. Confirm the capture.

After capture:

• The Klarna status updates to Captured
• PrestaShop updates the order status based on your configuration
• Klarna charges the customer based on the selected payment plan

If you ship an order in multiple shipments, you can capture only the items or amounts being shipped.

To perform a partial capture:

1. Open the purchase.
2. Select Capture order.
3. Choose individual items or enter a partial amount.
4. Confirm the capture.

The module prevents capturing more than the remaining authorized amount.

You can cancel a Klarna order only if the payment is still authorized and has not been captured.

To cancel:

1. Open the purchase.
2. Select Cancel order.
3. Confirm the cancellation.

After cancellation:

• The Klarna authorization is voided
• PrestaShop updates the order status to the canceled status you selected during configuration

Refunds apply only to captured purchases. You can refund the full amount or refund item by item or by custom amount.

1. Open the purchase.
2. Select Refund order.
3. Select all items or the full amount.
4. Confirm the refund.

1. Open the purchase.
2. Select Refund order.
3. Choose specific items or enter a partial amount.
4. Confirm the refund.

After the refund:

• Klarna updates the customer’s payment schedule
• The refund event appears in the Klarna history

If only part of the purchase is captured, Klarna keeps the remaining amount authorized until you release it.

To release the remaining authorization:

1. Open the purchase.
2. Select Release remaining authorization.

This clears the remaining authorization, ensuring the customer is not expecting additional charges.

When tracking numbers are added in PrestaShop, the Klarna module automatically sends shipment details to Klarna during the capture event when supported.

Klarna provides the initial payment method only in English. Since PrestaShop requires localization across multiple languages, the initial payment method may not be shown to customers on the confirmation page.

This does not affect the purchase or post purchase functionality.
