#### The Sitecore Commerce 8.2.1 doesn’t support multi currency functionality in Braintree Payment Gateway, though **Braintree** supports multi currency itself . In my [previous post](https://www.brimit.com/blog/sitecore-commerce-8-multicurrency-support "Sitecore Braintree multi currency") I’ve described how to set up multi currency in Sitecore and now I want to describe how to enable multiple currencies featrue in the Plugin.Sample.Payments.Braintree plugin. First of all, we need to define Merchant Accounts for each currency that you want to have. Go to your sandbox account or production account in Braintree, then **Account -> Merchant Account Info -> New Sandbox Merchant Account**. ![braintree merchant account](https://www.brimit.com/-/media/images/blog/multicurrency1jpeg.png?la=en&hash=1C0C0A402A694A9BFF1BDB989682E06E) After that, we need additional configuration in all CommerceAuthoring configs under CommerceAuthoring\wwwroot\data\Environments\ We need to update BraintreeClientPolicy and add Merchants property: ``` { "$type": "Plugin.Sample.Payments.Braintree.BraintreeClientPolicy, Plugin.Sample.Payments.Braintree", "Environment": "sandbox", "MerchantId": "xxxxxxxx", "PublicKey": "xxxxxxxxxxxxx", "PrivateKey": "xxxxxxxxxxxxxxx", "Merchants": [ { "CurrencyCode": "BRL", "MerchantId": "{Merchant Account ID}" }, { "CurrencyCode": "EUR", "MerchantId": "{Merchant Account ID}" }, { "CurrencyCode": "GBP", "MerchantId": "{Merchant Account ID}" } ], "ConnectTimeout": 120000, "PolicyId": "0af6253f42184fd8ae0a61085980c03c", "Models": { "$type": "System.Collections.Generic.List`1[[Sitecore.Commerce.Core.Model, Sitecore.Commerce.Core]], mscorlib", "$values": [ ] } }, ``` In the code above you should replace {Merchant Account ID} on your Merchant Account ID for each currency. Now CommersAuthoring knows about available Merchants Accounts. Now we need to modify CreateFederatedPaymentBlock class in Plugin.Sample.Payments.Braintree project and add logic for Merchant Accounts: ``` [PipelineDisplayName(PaymentsBraintreeConstants.Pipelines.Blocks.CreateFederatedPaymentBlock)] public class CreateFederatedPaymentBlock : PipelineBlock { /// /// Runs the specified argument. /// /// The argument. /// The context. /// /// A cart with federate payment component /// public override Task Run(CartEmailArgument arg, CommercePipelineExecutionContext context) { Condition.Requires(arg).IsNotNull($"{this.Name}: The cart can not be null"); var cart = arg.Cart; if (!cart.HasComponent()) { return Task.FromResult(arg); } var payment = cart.GetComponent(); if (string.IsNullOrEmpty(payment.PaymentMethodNonce)) { context.Abort(context.CommerceContext.AddMessage( context.GetPolicy().Error, "InvalidOrMissingPropertyValue", new object[] { "PaymentMethodNonce" }, $"Invalid or missing value for property 'PaymentMethodNonce'."), context); return Task.FromResult(arg); } var braintreeClientPolicy = context.GetPolicy(); if (string.IsNullOrEmpty(braintreeClientPolicy?.Environment) || string.IsNullOrEmpty(braintreeClientPolicy?.MerchantId) || string.IsNullOrEmpty(braintreeClientPolicy?.PublicKey) || string.IsNullOrEmpty(braintreeClientPolicy?.PrivateKey) || braintreeClientPolicy.Merchants == null || !braintreeClientPolicy.Merchants.Any()) { context.CommerceContext.AddMessage( context.GetPolicy().Error, "InvalidClientPolicy", new object[] { "BraintreeClientPolicy" }, $"{this.Name}. Invalid BraintreeClientPolicy"); return Task.FromResult(arg); } try { var merchant = braintreeClientPolicy.Merchants.FirstOrDefault(x => x.CurrencyCode == cart.Totals.PaymentsTotal.CurrencyCode); var gateway = new BraintreeGateway(braintreeClientPolicy?.Environment, braintreeClientPolicy?.MerchantId, braintreeClientPolicy?.PublicKey, braintreeClientPolicy?.PrivateKey); var request = new TransactionRequest { Amount = payment.Amount.Amount, //fix MerchantAccountId = merchant?.MerchantId, PaymentMethodNonce = payment.PaymentMethodNonce, BillingAddress = ComponentsHelper.TranslatePartyToAddressRequest(payment.BillingParty, context), Options = new TransactionOptionsRequest { SubmitForSettlement = true } }; Result result = gateway.Transaction.Sale(request); if (result.IsSuccess()) { Transaction transaction = result.Target; payment.TransactionId = transaction?.Id; payment.TransactionStatus = transaction?.Status?.ToString(); payment.PaymentInstrumentType = transaction?.PaymentInstrumentType?.ToString(); //fix payment.Amount.CurrencyCode = transaction?.CurrencyIsoCode; var cc = transaction?.CreditCard; payment.MaskedNumber = cc?.MaskedNumber; payment.CardType = cc?.CardType?.ToString(); if (cc?.ExpirationMonth != null) { payment.ExpiresMonth = int.Parse(cc.ExpirationMonth); } if (cc?.ExpirationYear != null) { payment.ExpiresYear = int.Parse(cc.ExpirationYear); } } else { string errorMessages = result.Errors.DeepAll().Aggregate(string.Empty, (current, error) => current + ("Error: " + (int)error.Code + " - " + error.Message + "\n")); context.Abort(context.CommerceContext.AddMessage( context.GetPolicy().Error, "CreatePaymentFailed", new object[] { "PaymentMethodNonce" }, $"{this.Name}. Create payment failed :{ errorMessages }"), context); } return Task.FromResult(arg); } catch (BraintreeException ex) { context.Abort(context.CommerceContext.AddMessage( context.GetPolicy().Error, "CreatePaymentFailed", new object[] { "PaymentMethodNonce", ex }, $"{this.Name}. Create payment failed."), context); return Task.FromResult(arg); } } } ``` After all these small changes you have a complete Braintree integration with multi currency support working.
