Here is a working example, how to obtain an Access token.
You need to add NewtonSoft.Json nuget package to your project to run it.
public class TokenModel
{
[JsonProperty("access_token")]
public string AccessToken;
}
public async Task<string> GetToken()
{
var credentials = new Dictionary<string, string>();
credentials.Add("client_id", "YOUR_CLIENT_ID");
credentials.Add("client_secret", "YOUR_CLIENT_SECRET");
credentials.Add("grant_type", "YOUR_GRANT_TYPE");
credentials.Add("scope", "YOUR_SCOPE");
var content = new FormUrlEncodedContent(credentials);
using (HttpClient client = new HttpClient())
{
client.BaseAddress = new Uri("https://developer.api.autodesk.com");
var response = await client.PostAsync("/authentication/v1/authenticate", content);
if (response.IsSuccessStatusCode)
{
var responseData = await response.Content.ReadAsStringAsync();
return JsonConvert.DeserializeObject<TokenModel>(responseData).AccessToken;
}
}
}
And simple usage:
var token=await GetToken();
It is not perfect, I've tried to simplify all the moments.
