Root Cause

• Unsupported currency by acquirer account: The merchant’s payment processor or acquirer does not support transactions in the selected currency.
• Merchant account configuration issue: The merchant account is not enabled for handling the specified currency.
• Currency restrictions imposed by payment gateway: The gateway does not allow transactions in the provided currency for the merchant’s account.
• Unsupported currency for selected payment method: The payment method used does not support transactions in the chosen currency.

Troubleshooting and Solutions

• Reach out to gateway support to ensure the currency can be supported by the payment gateway and is enabled for your merchant account.
• Verify and update the merchant account settings to support the required transaction currencies.
• Recommend offering alternative currencies that are supported by the merchant’s payment gateway and acquirer.
• Advise the customer to choose a different payment method that supports the selected currency.
• Clearly communicate supported currencies during the checkout process to prevent transaction failures.
• Retry the transaction only after ensuring currency compatibility between the payment method and the merchant account.
