How to send a proper HTTP request?

I’ve an ready made link that will send an SMS message to user’s phone with THE OTP.

However, I’m using this way and I’m wondering if there is a better way to send the request. Also, how to make sure that I got an 200 OK response.

HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);
HttpWebResponse response = (HttpWebResponse)request.GetResponse();

response.Close();

Method 1

You can use HttpClient.

Example:

public class Client
{
  HttpClient _httpClient;
  public Client()
  {
    _httpClient=new HttpClient();
  }
  //async post,get request
  public async Task<string> sendGetRequest(string url)
  {
    var response= await _httpClient.GetAsync(url);
    if(response.IsSuccessStatusCode)
    {
     //if response has status code 200 do something
     //in this case I'm just converting the content of the response in string format
      string result=await response.Content.ReadStringAsync();
    }
    else
    {
      return "error";
    }
  }
  public async Task<string> sendPostRequest(string url,string bodyJson)
  {
    //Example sending a post request with json as body.
    var body=new StringContent(bodyJson, Encoding.UTF8, "application/json");
    var response= await _httpClient.PostAsync(url,body);
    if(response.IsSuccessStatusCode)
    {
     //if response has status code 200 do something
     //in this case I'm just converting the contntent of the response in string format
      string result=await response.Content.ReadStringAsync();
      return result;
    }
    else
    {
     return "error";
    }
  }
