https //api.powerbi.com/v1.0/myorg/datasets 403 forbidden

I gave all permission to my app but isues was something different.I was trying to get token based on azure active directy app client id and app secerete key.After doing google i found that i need to pass credentials of azure login account too.

Below code worked for me with valide token:

  private async void SetAccessToken()
        {
            List<KeyValuePair<string, string>> vals = new List<KeyValuePair<string, string>>();
            vals.Add(new KeyValuePair<string, string>("grant_type", "password"));
            vals.Add(new KeyValuePair<string, string>("scope", "openid"));
            vals.Add(new KeyValuePair<string, string>("resource", "https://analysis.windows.net/powerbi/api"));
            vals.Add(new KeyValuePair<string, string>("client_id", "..........."));
            vals.Add(new KeyValuePair<string, string>("client_secret", "........"));
            vals.Add(new KeyValuePair<string, string>("username", "................."));
            vals.Add(new KeyValuePair<string, string>("password", "................."));
            string TenantId = "............com";//your organizaion name
            string url = string.Format("https://login.windows.net/{0}/oauth2/token", TenantId);
            HttpClient hc = new HttpClient();
            HttpContent content = new FormUrlEncodedContent(vals);
            HttpResponseMessage hrm = hc.PostAsync(url, content).Result;
            string responseData = "";
            if (hrm.IsSuccessStatusCode)
            {
                Stream data = await hrm.Content.ReadAsStreamAsync();
                using (StreamReader reader = new StreamReader(data, Encoding.UTF8))
                {
                    responseData = reader.ReadToEnd();
                }
            }
            AccessToken Token = JsonConvert.DeserializeObject<AccessToken>(responseData);
            var result = await CallResoureApi(Token);
        }

   public async Task<string> CallResoureApi(AccessToken token)
        {
            var baseAddress = new Uri("https://api.powerbi.com/");
            string jsonresult = "";
            string requestUrl = baseAddress + "v1.0/myorg/datasets";
            var client = new RestClient(baseAddress);
            var request = new RestRequest("v1.0/myorg/datasets", Method.GET);
            request.AddHeader("authorization", "Bearer " + token.access_token);

            // execute the request
            IRestResponse response = client.Execute(request);
            var content = response.Content;
            return content;
        }
