title: Sending a message to whatsapp groups through twilio with asp.net core
body: <p>I am trying to use whatsapp business api for my application with twilio. I already have read the documentation of whatsapp business api. My question is, can we use twilio to send the messages to different whatsapp group based on id. 
  For example, If I have 3 groups such as Students, Professors, Assistants and based on each different group I want to send a specific message such as Hi to Students, Hello to Professors and Hey to Assistants. 
  What I know till now that Whatsapp differentiate everything with specific id, for instance, <code>chat.whatsapp.com/DeUzzel9O13231</code> </p>
  
  <p>I also have worked with the twilio and whatsapp api where you can send a message from your twilio number to your whatsapp number like below</p>
  
  <pre><code>using System;
  using Twilio;
  using Twilio.Rest.Api.V2010.Account;
  
  
  class Program 
  {
      static void Main(string[] args)
      {
          // Find your Account Sid and Token at twilio.com/console
          // DANGER! This is insecure. See http://twil.io/secure
          const string accountSid = "ACXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX";
          const string authToken = "your_auth_token";
  
          TwilioClient.Init(accountSid, authToken);
  
          var message = MessageResource.Create(
              body: "Join Earth's mightiest heroes. Like Kevin Bacon.",
              from: new Twilio.Types.PhoneNumber("+15017122661"),
              to: new Twilio.Types.PhoneNumber("+15558675310")
          );
  
          Console.WriteLine(message.Sid);
      }
  }
  </code></pre>
  
  <p>The code above is only for sending a message to a specific number. Can I do the same thing with the groups? If yes, How? Is there any documentation for that? </p>
  
  <p>Thanks.</p>
