# Deprecation of fractional ISK charges and refunds

Multiple card networks (e.g. Visa, Mastercard) changed their requirements for Icelandic króna (ISK) payments to only permit whole-unit amounts starting 14 April 2023. For instance, an ISK 40.10 payment won't be accepted and needs to be a whole amount such as ISK 40.00 or ISK 41.00.
If you've previously created ISK charges with your Stripe account, you need to update your integration and price lists so that they accommodate whole amounts only.
Since 14 April 2023, the Stripe API enforces that all amounts in ISK are stated in multiples of 100. Attempts to specify fractional króna after this date results in the following response:
```
400 invalid_charge_amount_no_decimal_compatible: Invalid amount. 
Currency ISK has become effectively zero-decimal and charged amounts must be evenly divisible by 100. 
See https://stripe.com/docs/currencies#special-cases for more information.
```
Any Products and Prices in króna need to be represented with whole amounts, along with any references to these amounts in your Subscriptions, Invoices, Payment Links and Checkout.
ISK will remain a two-decimal currency in the Stripe API, and an ISK amount of `100` will continue to represent 1 króna.
**Refunds**
After 14 April 2023, refunding prior charges made in fractional króna result in the same `invalid_charge_amount_no_decimal_compatible` response. As a workaround, you can refund a partial amount, for example, the refund amount rounded down to the nearest whole krona. You may find it easier to manually create refunds from the Stripe Dashboard as needed, instead of building this into your integration.
