I tried to use your function, but it didn't help.

            HttpWebRequest request = System.Net.HttpWebRequest.CreateHttp(String.Format("https://api.powerbi.com/v1.0/myorg/groups/{0}/reports/GenerateToken", groupID));

            string PostData = "{"+

            byte[] byteArray = System.Text.Encoding.UTF8.GetBytes(PostData); 

            try
            {
                //Write JSON byte[] into a Stream
                using (Stream writer = request.GetRequestStream())
                {
                    writer.Write(byteArray, 0, byteArray.Length);
                    var response = (HttpWebResponse)request.GetResponse(); 
                    var responseJson = new StreamReader(response.GetResponseStream()).ReadToEnd();
                    dynamic responseString = JsonConvert.DeserializeObject<dynamic>(responseJson.ToString());
                    embedToken = responseString["token"];

            catch (WebException wex)

                    using (var errorResponse = (HttpWebResponse)wex.Response)
                    {
                        using (var reader = new StreamReader(errorResponse.GetResponseStream()))

                            string errorString = reader.ReadToEnd();
                            dynamic respJson = JsonConvert.DeserializeObject<dynamic>(errorString);
                            Console.WriteLine(respJson.toString());
                            //TODO: use JSON.net to parse this string and look at the error message
                        }
                    }
                }
            }

            return embedToken;
        }
    }
}

On line: 

using (Stream writer = request.GetRequestStream())

program thinks for approximately 30 seconds and then goes to catch block.

In catch block if statement is false (so, Response == null) and program just goes out from catch.

That's all.

 

I still don't understant why it happens because I just use this guide for POST requests (https://msdn.microsoft.com/library/mt784614.aspx). And it's up to date (Updated: July 21, 2017), so, I don't understand.

 

I'll appresiate any help.

Have you got any API console tool for testing purpose? If not, I'd suggest using POSTMAN.

So beforing coding in C#, can you test this GenerateToken in postman? For any issue, feel free to post.
