Braintree not updating user preferred/default payment method

Question

When a customer wants to choose his payment method while creating a sale order I see it changed in the DropInUI(small tick mark) and I assume that should become the default payment method but that is not what happens at my server, I still get the payment token for the first one.

Here's what I'm doing:

String token = btGateway.customer().find(customerId).getDefaultPaymentMethod().getToken().toString();

Case:

• Customer A places an order with his credit card - All Good
• Customer A places another order, this time adding a paypal account and the drop in ui shows two options, customer selects his preferred payment method - All good

At my server I don't get a different payment token for credit card and paypal.

UPDATE:

Based on the Ryan's answer, I have a new query: How do you get the token for the payment method selected from the dropin(is there a delegate method that returns the payment method in iOS). Is there a way to identify the payment method selected by user so I fetch the token for it?

Answer 1

All right, after nice inputs from Ryan and here. I figured out a way to make my payment method as default and fetch its token to make a sale with that later on. Later on since I am using marketplace I can't create a sale with service fee so I fetched the payment method from the token and went on to make a sale. Not sure if what I did is the best way but it serves the purpose.

Here's what I did:

Make the user selected payment method as default and save its token:

if(customerId!=null){
            PaymentMethodRequest request = new PaymentMethodRequest()
            .customerId(customerId)
            .paymentMethodNonce("paymentMethodNonceFromClient")
            .options()
                .makeDefault(true)
            .done();

            Result<PaymentMethod> result = (Result<PaymentMethod>) btGateway.paymentMethod().create(request);
            if(result.isSuccess())
                token = btGateway.customer().find(customerId).getDefaultPaymentMethod().getToken().toString();

Later on when making a transaction find the payment method and apply fee if it is a CreditCard:

PaymentMethod payMethod = btGateway.paymentMethod().find(token);
            if(payMethod instanceof CreditCard){
                request = new TransactionRequest()
                .amount(new BigDecimal(txnAmount))
                .paymentMethodToken(token)
                .merchantAccountId("merchantAccountId")
                .serviceFeeAmount(new BigDecimal(serviceFee));
            }else{
                request = new TransactionRequest()
                .amount(new BigDecimal(txnAmount))
                .paymentMethodToken(token);
            }
