I am using Visual Studio 2017, and install SFMC.FuelSDK by using Nuget.

I use this:

        NameValueCollection parameters = new NameValueCollection();
        parameters.Add("clientId", "xxxxxxxxxxxxx");
        parameters.Add("clientSecret", "xxxxxxxxxxxxxxxxx");
        ETClient myclient = new ETClient(parameters);

and get (401) Unauthorized. I get clientId and clientSecret from App Center. I tested my clientId and clientSecret with URL (https://auth.exacttargetapis.com/v1/requestToken), and they are valid.

Does anyone know what I did wrong or what should I try?


please add the following line and try again:

parameters.Add("authEndPoint", "https://auth.exacttargetapis.com/v1/requestToken?legacy=1");

  • Is there a document showing about this parameter? – Ponpirat Nov 6 '17 at 1:59
