Add SMS Controller

Right-click on the Controllers Folder and select add->Controller. Select "MVC Controller - Empty" and name it SmsController.

Add a using statements for Vonage.Messaging and Vonage.Utility at the top of this file.

Add Receive SMS Action

Finally we'll need to add a route to receive the webhook from Vonage, parse out the SMS data structure, and print some stuff to our console:

[HttpGet("/webhooks/inbound-sms")]
public IActionResult InboundSms()
{
    var sms = WebhookParser.ParseQuery<InboundSms>(Request.Query);
    Console.WriteLine("SMS Received");
    Console.WriteLine($"Message Id: {sms.MessageId}");
    Console.WriteLine($"To: {sms.To}");
    Console.WriteLine($"From: {sms.Msisdn}");
    Console.WriteLine($"Text: {sms.Text}");
    return Ok();
}
