Using UCWA api and getting error when trying to connect through code C#

I am using UCWA api to create Lync Meeting URL but I am getting error in a step,

and it is related to LYNC so trying to figure out how to resolve. My code is 

string url_00   = ucwaMsRtcOAuth;   
var authDic_00  = new Dictionary<string, string>();  

authDic_00.Add("grant_type", "password");  
authDic_00.Add("username", String.Format("{0}\\{1}", ucwaAdDomain, ucwaAdUser));  
authDic_00.Add("password", ucwaAdPassword);  

httpClient.DefaultRequestHeaders.Remove("Accept");  
httpClient.DefaultRequestHeaders.Add("Accept", "application/vnd.microsoft.com.ucwa+xml");  

var res_00 = await httpClient.PostAsync(url_00, new FormUrlEncodedContent(authDic_00));  

string res_00_request   = res_00.RequestMessage.ToString();  
string res_00_headers   = res_00.Headers.ToString();  
string res_00_status    = res_00.StatusCode.ToString();  
var res_00_content      = await res_00.Content.ReadAsStringAsync();

and output of last 4 variable is as

res_00.RequestMessage

Method: POST, RequestUri: 'https://lynceu1webint.MYCOMPANYNAME.com/WebTicket/oauthtoken',

There are a few potential reasons you are seeing that error response:

  • Incorrect domain\username combo
  • Incorrect password
  • Incorrect grant string

If you are intending to use domain and password with the password grant_type make sure your grant string resembles:

grant_type=password&domain\username&password=*******

If that still does not work you may be required to provide the SIP/Account used to login in that user to the desktop version of Skype for Business. This grant string would look like:

grant_type=password&[email protected]&password=*******
