Twilio REST API and TwiML Libraries for .NET

Twilio provides a HTTP-based API for sending and receiving phone calls and text messages. Learn more on twilio.com.

More documentation for this library can be found here.

Versions

twilio-csharp uses a modified version of Semantic Versioning for all changes. See this document for details.

Migrate from earlier versions

See the migration guide here. Also, if you were using the Twilio.Mvc package, that has been replaced by the Twilio.AspNet.Mvc package which is compatible with this version of the library.

TLS 1.2 Requirements

New accounts and subaccounts are now required to use TLS 1.2 when accessing the REST API. "Upgrade Required" errors indicate that TLS 1.0/1.1 is being used. With .NET, you can enable TLS 1.2 using this setting:

System.Net.ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12;

Supported .NET versions

This library supports .NET applications that utilize .NET6+.

Installation

The best and easiest way to add the Twilio libraries to your .NET project is to use the NuGet package manager.

With Visual Studio IDE

From within Visual Studio, you can use the NuGet GUI to search for and install the Twilio NuGet package. Or, as a shortcut, simply type the following command into the Package Manager Console:

Install-Package Twilio

With .NET Core Command Line Tools

If you are building with the .NET Core command line tools, then you can run the following command from within your project directory:

dotnet add package Twilio

Sample usage

The examples below show how to have your application initiate and outbound phone call and send an SMS message using the Twilio .NET helper library:

TwilioClient.Init("ACCOUNT_SID", "AUTH_TOKEN");

var call = CallResource.Create(
    new PhoneNumber("+11234567890"),
    from: new PhoneNumber("+10987654321"),
    url: new Uri("https://my.twiml.here")
);
Console.WriteLine(call.Sid);

var message = MessageResource.Create(
    new PhoneNumber("+11234567890"),
    from: new PhoneNumber("+10987654321"),
    body: "Hello World!"
);
Console.WriteLine(message.Sid);

Specify Region and/or Edge

To take advantage of Twilio's Global Infrastructure, specify the target Region and/or Edge for the client:

TwilioClient.SetRegion("au1");
TwilioClient.SetEdge("sydney");

This will result in the hostname transforming from api.twilio.com to api.sydney.au1.twilio.com.

Enable debug logging

There are two ways to enable debug logging in the default HTTP client. You can create an environment variable called TWILIO_LOG_LEVEL and set it to debug or you can set the LogLevel variable on the client as debug:

TwilioClient.SetLogLevel("debug");

Handle exceptions

For an example on how to handle exceptions in this helper library, please see the Twilio documentation.

Generate TwiML

To control phone calls, your application needs to output TwiML.

// TwiML classes can be created as standalone elements
var gather = new Gather(numDigits: 1, action: new Uri("hello-monkey-handle-key.cshtml"), method: HttpMethod.Post)
    .Say("To speak to a real monkey, press 1. Press 2 to record your own monkey howl. Press any other key to start over.");

// Attributes can be set directly on the object
gather.Timeout = 100;
gather.MaxSpeechTime = 200

// Arbitrary attributes can be set by calling set/getOption
var dial = new Dial().SetOption("myAttribute", 200)
                     .SetOption("newAttribute", false);

// Or can be created and attached to a response directly using helper methods
var response = new VoiceResponse()
    .Say("Hello Monkey")
    .Play(new Uri("http://demo.twilio.com/hellomonkey/monkey.mp3"))
    .Append(gather)
    .Append(dial);

// Serialize the TwiML objects to XML string
Console.WriteLine(response);

/*
<?xml version="1.0" encoding="utf-8"?>
<Response>
  <Say>Hello Monkey</Say>
  <Play>http://demo.twilio.com/hellomonkey/monkey.mp3</Play>
  <Gather numDigits="1" action="hello-monkey-handle-key.cshtml" method="POST" timeout="100" maxSpeechTime="200">
    <Say>To speak to a real monkey, press 1. Press 2 to record your own monkey howl. Press any other key to start over.</Say>
  </Gather>
  <Dial myAttribute="200" newAttribute="false"></Dial>
</Response>
*/
