HttpClient - Send a batch of requests

Question

I want to iterate a batch of requests, sending each one of them to an external API using HttpClient class.

  foreach (var MyRequest in RequestsBatch)
  {

It doesn't look like you're actually running a seperate thread for each request. Try something like this:

var taskList = new List>();

foreach (var myRequest in RequestsBatch)
{
    taskList.Add(GetResponse(endPoint, myRequest));
}

try
{
    Task.WaitAll(taskList.ToArray());
}
catch (Exception ex)
{
}

public Task GetResponse(string endPoint, string myRequest)
{
    return Task.Run(() =>
        {
            HttpClient httpClient = new HttpClient();

            HttpResponseMessage response = httpClient.PostAsJsonAsync(
                 string.Format("{0}api/GetResponse", endpoint), 
                 myRequest, 
                 new CancellationTokenSource(TimeSpan.FromMilliseconds(5)).Token);

            JObject resultResponse = response.Content.ReadAsAsync();
        });
}
