Hi Amila,
I am using couple "nuget" packages "Microsoft.AspNet.WebApi.Client" & "HttpMultipartParser" to achieve the same. Here you go:

using Newtonsoft.Json;
namespace DownloadZipFile
{
public static class Program
{
static string filePath;
static void Main(string[] args)
{
filePath = @"D:\Output";
CallWebAPIAsync().Wait();
}
static async Task CallWebAPIAsync()
{
using (var client = new HttpClient())
{
client.BaseAddress = new Uri("https://cpf-ue1.adobe.io/ops/id/");
client.DefaultRequestHeaders.Accept.Clear();
client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("text/plain"));
client.DefaultRequestHeaders.Add("x-api-key", "{Your CLIENT ID)}");
client.DefaultRequestHeaders.Add("Authorization", "Bearer " + "{Your Authorization token}");
//GET Method
System.Net.ServicePointManager.SecurityProtocol = System.Net.SecurityProtocolType.Tls | System.Net.SecurityProtocolType.Tls11 | System.Net.SecurityProtocolType.Tls12;
HttpResponseMessage response = await client.GetAsync("{Your x-request-id}");
if (response.IsSuccessStatusCode)
{
var parser = MultipartFormDataParser.Parse(response.Content.ReadAsStreamAsync().Result);
string parserParameters = parser.Parameters[0].Data;
Root model = JsonConvert.DeserializeObject<Root>(parserParameters);
List<ElementsRendition> listElements = model.CpfOutputs.elementsRenditions;
Dictionary<string,string> fileNameTypeDictionary = new Dictionary<string,string>();
foreach(ElementsRendition a in listElements)
{
fileNameTypeDictionary.Add(a.CpfLocation, a.DcFormat);
}
foreach (var f in parser.Files)
{
Stream data = f.Data;
string fileName = Path.Combine(filePath,"{0}.{1}");
string fileExtension = "json";
if (fileNameTypeDictionary.ContainsKey(f.Name)) fileExtension = fileNameTypeDictionary[f.Name];
switch(fileExtension)
{
case "text/csv":
File.WriteAllBytes(string.Format(fileName, f.Name, "csv"), ReadFully(data));
break;
case "image/png":
File.WriteAllBytes(string.Format(fileName, f.Name, "png"), ReadFully(data));
break;
default:
File.WriteAllBytes(string.Format(fileName, f.Name, "json"), ReadFully(data));
break;
}
}
}
else
{
Console.WriteLine("Internal server Error");
}
}
}
public static byte[] ReadFully(Stream input)
{
byte[] buffer = new byte[16 * 1024];
using (MemoryStream ms = new MemoryStream())
{
int read;
while ((read = input.Read(buffer, 0, buffer.Length)) > 0)
{
ms.Write(buffer, 0, read);
}
return ms.ToArray();
}
}
}
}
