how can i get payment without payment method nonce?

Question

i need to get payment with Braintree and as far as i understand from the Braintree's documentation,followed the these steps;

1. created a Gateway

    BraintreeGateway Gateway = new BraintreeGateway
   {
       Environment = Braintree.Environment.SANDBOX,
       MerchantId = "xxxxxxxxxxx",
       PublicKey = "yyyyyyyyyyyyyyy",
       PrivateKey = "zzzzzzzzzzzzzzz",
   };
   

2. created a Customer

   var request = new CustomerRequest
   {
       FirstName = "firstName",
       LastName = "lastName",
       Email = "eMail",
       Phone = "phone",
   };
   string CustomerId = Gateway.Customer.Create(request).Target.Id;
   

3. created a credit card of the customer as using returened customerid

   var creditCardRequest = new CreditCardRequest
   {
       CustomerId = CustomerId,
       Number = "credit_card_number",
       ExpirationDate = "ex_date",
       CVV = "cc_cvv"
   };
   
   string creditCardToken = Gateway.CreditCard.Create(creditCardRequest).Target.Token;
   

what then? need a transaction with amount but the using what i found is not related with customer or credit card. Can someone help about what i should do next? Especially i need a method without 3d secure.

Answer 1

The answer of support: To create a transaction, you must include an amount and either a paymentMethodNonce, a paymentMethodToken, or a customerId. Passing a customerId is equivalent to passing the paymentMethodToken of the customer's default payment method.

  TransactionRequest transactionRequest = new TransactionRequest()
    {
        Amount = amount,
        CustomerId = customer.Id,
        Options = new TransactionOptionsRequest
        {
            SubmitForSettlement = true
        }
    };

    Result<Transaction> result = Gateway.Transaction.Sale(transactionRequest);
