Hi,

Our Braintree account has multiple Merchant Accounts for different currencies, the default one is for USD, and there are also for AUD, CAD, EUR, GBP.

Our Merchello shop API handles multiple currencies but regardless of the selected currency Braintree uses the default which is the USD one.

I'm trying to set MerchantAccountId = "accountidfor_GBP" like braintree api docs but I'm not sure where.

TransactionRequest request = new TransactionRequest
{
    Amount = 100.00M,
    MerchantAccountId = "your_merchant_account",
    PaymentMethodNonce = nonceFromTheClient
};

This is how I'm doing the payment

// Get the payment method
var paymentGatewayMethod = checkoutManager.Payment.GetPaymentGatewayMethods().FirstOrDefault();
var paymentMethod = paymentGatewayMethod.PaymentMethod;
    checkoutManager.Payment.SavePaymentMethod(paymentMethod);

// Create the arguments
var args = new ProcessorArgumentCollection();
    args.Add("cardholderName", cardholderName);
    args.Add("cardNumber", cardNumber);
    args.Add("expireMonth", expireMonth);
    args.Add("expireYear", expireYear);
    args.Add("cardCode", cardCode);

    //tried to add it here, but doesn't work 
    args.Add("MerchantAccountId", "account_id_for_GBP");

     // Set the nonce
     args.SetPaymentMethodNonce(paymentMethodNonce);

     // Attempt a payment
     authorisationAttempt = checkoutManager.Payment.AuthorizePayment(paymentMethod.Key, args);

Any help is much appreciated.

Thanks !

Alex
