How does Omise handle currency conversion?

Last updated on August 23, 2019

Omise supports charges in several currencies depending on the country in which your account is registered.

See our multi-currency documentation for supported currencies.


Multi-currency charges are automatically converted into your local currency before being deposited to your account. When we convert currencies on your behalf, the rate used is approximately 2-4% above the mid-market exchange rate.

You can retrieve the exchange rate used for a particular conversion in real time using the Forex API.


The exchange rate used is the rate at the time you create the refund.

Disputes and Chargebacks

The exchange rate used is the rate at the time we are notified of the dispute or chargeback by our partnering banks.

Please be aware that exchange rates do fluctuate. Refunds, disputes, and chargebacks will reflect these fluctuations, for which you will be liable.
