Yes, our module fully supports multiple currencies through multiple Braintree merchant accounts. In order to use multiple currencies you will need to contact Braintree to get more information on having multiple merchant accounts. Each merchant would have a different id which you would supply in the payment gateway “Merchant Currencies” field. Please note that the “Merchant ID” field will still contain your primary merchant account id.
Your Merchant Currencies field would look like the above example. Each currency and merchant id is on its own line in the format CURRENCY:MERCHANT_ACCOUNT_ID. Our module will automatically find the correct merchant ID to use based on the customer’s selected currency.
Note that you will need a merchant id for each currency your WHMCS system supports.
