senderAuthenticationTokens call returns error code 415 Unsupported Media Type
Wednesday, December 9, 2015 at 09:58amI can't seem to get the senderAuthenticationToken.  I'm  receiving a 415 error code, Unsupported Media Type.  Any ideas what I'm doing wrong?
        PackageId packageId = eslClient.CreatePackage(superDuperPackage);
        using (var client = new WebClient())
        {
            byte[] response = client.UploadValues("https://sandbox.esignlive.com/api/senderAuthenticationTokens", new System.Collections.Specialized.NameValueCollection()
            {
                { "Content-Type", "application/json" },
                { "Accept", "application/json" },
                { "Authorization", "Basic " + apiKey},
                { "packageId", packageId.Id}
            });
            string result = System.Text.Encoding.UTF8.GetString(response);
        }
