# Duration of authorizations

> How long Dintero holds an authorization for each payment method before it expires.

When a customer pays, Dintero creates an authorization that reserves the amount at their bank. You must capture the payment before the authorization expires, or the customer will need to pay again.

## Quick reference

| Payment method        | Authorization window                        |
| --------------------- | ------------------------------------------- |
| Klarna                | 28 days (auto-extended to 6 months)         |
| Walley                | 90 days                                     |
| Card                  | \~7 days (up to 30+ days depending on bank) |
| Vipps (Visa)          | 7 days                                      |
| Vipps (Visa Electron) | 5 days                                      |
| Vipps (Mastercard)    | 30 days                                     |
| Swish                 | No authorization — captured immediately     |

<Warning>
  If an authorization expires before you capture, the customer must pay again. Use a [payment link](/docs/integrations/support/send-payment-link) to recover the order.
</Warning>

## Klarna

You have **28 days** to capture. Dintero automatically extends the authorization after 23 days, up to a maximum of 6 months, so orders do not expire without warning.

<Note>
  Auto-extension does not apply when the customer selects **Pay by card** within Klarna checkout.
</Note>

Klarna sends email notifications before each authorization period expires.

The customer's invoice is only generated when you capture — not at authorization. For **installment** orders, the full authorized amount shows as Klarna debt until you capture or cancel.

For **partial captures**, the remaining authorized amount receives a fresh 28-day window. You can extend it manually before expiry, up to 6 months in total.

## Walley

You have **90 days** to capture Walley transactions (invoice and installments). The customer's invoice is generated when you capture.

## Card payments

Card authorizations are typically valid for around **7 days**, but this varies by the customer's bank. Most cards allow captures beyond 30 days as long as the card remains valid and funded.

## Vipps

The authorization window depends on the card type linked to the customer's Vipps account:

| Card type     | Authorization valid for |
| ------------- | ----------------------- |
| Visa          | 7 days                  |
| Visa Electron | 5 days                  |
| Mastercard    | 30 days                 |

The customer's bank may release the reservation earlier than these limits. Capture is guaranteed within these windows if funds are available.

## Swish

Swish skips the authorization stage entirely. Approved payments go directly to **Captured**, so there is no authorization window to manage.
