Send requests with C#

Introduction

After authorizing API requests as required and setting up a C# environment, you can use the script below to send API requests using C#:

using System.Security.Cryptography;
using System.Text;


namespace Devo
{
    class Program
    {
        public void callDevoAPI()
        {

            String key = "YOUR-DEVO-API-KEY-GOES-HERE";
            String secret = "YOUR-DEVO-API-SECRET-GOES-HERE";
            String cloud = "us";
            String query = "from box.unix select *";
            String body = "" +
                "{\"from\": \"2h\", " +
                "\"to\": \"now\", " +
                "\"query\":\"" + query + "\"," +
                "\"limit\": 10, " +
                "\"mode\": { \"type\":\"csv\"}}";

            var httpclient = new HttpClient();
            httpclient.Timeout = TimeSpan.FromMinutes(9999);
            String queryEndpoint = "https://apiv2-" + cloud + ".devo.com/search/query";
            var webRequest = new HttpRequestMessage(HttpMethod.Post, queryEndpoint)
            {
                Content = new StringContent(body, Encoding.UTF8, "application/json")
            };

            String unixTimestamp = (DateTime.UtcNow.Subtract(new DateTime(1970, 1, 1))).TotalMilliseconds.ToString();
            unixTimestamp = unixTimestamp.Substring(0, unixTimestamp.IndexOf("."));
            String data = key + body + unixTimestamp;
            byte[] byteArrayData = Encoding.UTF8.GetBytes(data);
            byte[] byteArraySecret = Encoding.UTF8.GetBytes(secret);
            var hash = new HMACSHA256(byteArraySecret);
            byte[] byteSigned = hash.ComputeHash(byteArrayData);
            var hexString = BitConverter.ToString(byteSigned);
            String sign = hexString.Replace("-", "").ToLower();

            httpclient.DefaultRequestHeaders.Add("x-logtrust-apikey", key);
            httpclient.DefaultRequestHeaders.Add("x-logtrust-timestamp", unixTimestamp);
            httpclient.DefaultRequestHeaders.Add("x-logtrust-sign", sign);

            try
            {
                var response = httpclient.Send(webRequest);
                Console.WriteLine(response.Content.ReadAsStringAsync().Result);
            }

            catch (Exception ex)
            {
                Console.WriteLine("Exception occured: " + ex.Message);
            }
         }

        public static void Main(string[] args)
        {
            Program p = new Program();
            p.callDevoAPI();
        }
    }
}

Parameters

Replace the following parameters in the script using your own information:

`key`	Enter the API key of your Devo domain. To get it, access Devo and go to Administration → Credentials → Access Keys. Learn more in this article.
`secret`	Enter the API secret of your Devo domain. To get it, access Devo and go to Administration → Credentials → Access Keys. Learn more in this article.
`cloud`	Specify the Devo cloud of your domain. The available options are `us`, `eu`, `es`, `ca` and `saas`
