//Azure Application Client Key Secret
private const string ClientSecret = "SECRET VALUE FROM AZURE";
//Resource CRM Url
private const string Resource = "test.crm.dynamics.com";
//Guid is your Azure Active Directory Tenant Id private const string Authority = "login.microsoftonline.com/00000000-0000-0000-0000-000000000003";

public static string GetAccessToken() { string accessToken = string.Empty; AuthenticationContext authContext = new AuthenticationContext(Authority); //No prompt for credentials ClientCredential credentials = new ClientCredential(ClientId, ClientSecret); _authResult = authContext.AcquireToken(Resource, credentials); return _authResult.AccessToken; }
