Supported Currencies

Exirom processes payments in the currencies listed below. Supported currencies depend on your merchant account configuration and the payment method used. Contact your account manager to confirm which currencies are enabled for your MID.

All currency fields in API requests accept ISO 4217 three-letter codes.

#Card Payments

Card payments support a broad set of currencies across major card networks (Visa, Mastercard). The commonly supported currencies include:

Currency conversion: If orderCurrency differs from the processing currency, Exirom applies FX conversion. Both orderAmount and processedAmount are returned in the webhook callback, along with the conversionRate. See FX Refund Flow for refund behavior when currencies differ.

#APM Payments

APM currency support varies by payment method and region. Each APM type is tied to specific currencies and countries:

#Hosted Payment Page (HPP)

HPP inherits the currency support of the underlying payment methods available for your merchant account. The currency field in POST /api/v1/payments/intent controls which currency the checkout is initiated in.

#Amount Format

All amounts are passed as strings representing decimal values in the major currency unit (dollars, euros, etc. — not cents):

"amount": "100.00"   ✓
"amount": "10000"    ✗  (would be interpreted as 10,000 units, not 100.00)
"amount": 100.00     ✗  (must be a string)

Values with more than two decimal places are automatically rounded.

Zero-decimal currencies: For currencies like JPY that have no minor unit, pass the full amount as a whole number string: "amount": "1000" for ¥1,000.
