ASP.NET MVC C# PayPal Rest API - UNAUTHORIZED_PAYMENT

Question

I'm trying to integrate the paypal rest api to my web application. After digging through all available sources I'm stuck.

I'm using the paypal rest api example from here: GitHub-PayPal-DotNet-Sample

I updated the nuget to the latest sdk version and replaced the cliendId and secret with my own live keys.

Now my problem is, always I choose "credit_card" I get an 401 error response:

{ "name": "UNAUTHORIZED_PAYMENT", "message": "Unauthorized payment", "information_link": " https://developer.paypal.com/webapps/developer/docs/api/#UNAUTHORIZED_PAYMENT ", "debug_id": "1d25a990be5db" }

I set the currency to "CHF" (application runs in Switzerland) and the amount to "0.05" for testing purposes. I also retrieve a valid access token!

Tried various credit cards some belongs to my merchant account some not, still the same error.

With the option "paypal" it seems to work, but I want to offer credit cards directly within the application.

Is something not available in Switzerland? Any suggestions for this problem? Did I overlook something?

Thanks in advance!

Sample Code:

        Payment pay = null;

        Amount amount = new Amount();
        amount.currency = "CHF";
        amount.total = "0.05";

        Transaction transaction = new Transaction();
        transaction.amount = amount;
        transaction.description = orderDescription;

        List<Transaction> transactions = new List<Transaction>();
        transactions.Add(transaction);

        FundingInstrument fundingInstrument = new FundingInstrument();
        CreditCardToken creditCardToken = new CreditCardToken();
        creditCardToken.credit_card_id = GetSignedInUserCreditCardID(email);
        fundingInstrument.credit_card_token = creditCardToken;

        List<FundingInstrument> fundingInstrumentList = new List<FundingInstrument>();
        fundingInstrumentList.Add(fundingInstrument);

        Payer payer = new Payer();
        payer.funding_instruments = fundingInstrumentList;
        payer.payment_method = paymntMethod.ToString(); //credit_card

        Payment pyment = new Payment();
        pyment.intent = "sale";
        pyment.payer = payer;
        pyment.transactions = transactions;

        pay = pyment.Create(AccessToken);

        return pay;
