Duo Auth API - Ping

See more Duo Auth MFA Examples

The /ping endpoint acts as a "liveness check" that can be called to verify that Duo is up before trying to call other Auth API endpoints. Delphi ActiveX

uses
    Winapi.Windows, Winapi.Messages, System.SysUtils, System.Variants, System.Classes, Vcl.Graphics,
    Vcl.Controls, Vcl.Forms, Vcl.Dialogs, Vcl.StdCtrls, Chilkat_TLB;
