Sending a message to whatsapp groups through twilio with asp net core


ASP.NET is a popular programming language used for building web applications. In this article, we will explore how to send a message to groups Twilio with ASP.NET Core.

Setting up Twilio

Before we can sending messages to WhatsApp groups, we need to set up Twilio in our ASP.NET Core . Twilio is a cloud communications platform that provides APIs for sending and receiving messages.

To get started, sign up for a Twilio account and obtain your Account SID and Auth Token. These credentials will be used to authenticate your requests to the Twilio API.

Next, install the Twilio package in your ASP.NET Core project. Open the Package and run the following command:

Install-Package Twilio

Sending a Message to WhatsApp Groups

Once Twilio is set up, we can start sending messages to WhatsApp groups. First, we need to create an instance of the Twilio client by passing in our Account SID and Auth Token:

var accountSid = "YOUR_ACCOUNT_SID";
var authToken = "YOUR_AUTH_TOKEN";
var twilioClient = new TwilioRestClient(accountSid, authToken);

Next, we need to specify the WhatsApp 's identifier and the message we want to send:

var groupId = "YOUR_GROUP_ID";
var message = "Hello from Twilio!";

var messageOptions = new CreateMessageOptions(new PhoneNumber("whatsapp:" + groupId))
    Body = message

Finally, we can send the message using the Twilio client:

var result = twilioClient.SendMessage(messageOptions);

The SendMessage method returns a MessageResource object, which information about the sent message, such as its unique identifier and status.


In this article, we have learned how to send a message to WhatsApp groups using Twilio with ASP.NET Core. By following the steps outlined above, you can easily integrate Twilio into your ASP.NET Core application and start sending messages to WhatsApp groups.

Remember to replace the placeholders with your actual Twilio credentials and WhatsApp group identifier before running the code.
