A module for using the Twilio REST API and generating valid TwiML. Click here to read the full documentation.

Recent Update

As of release 5.1.0, Beta and Developer Preview products are now exposed via the main twilio-ruby artifact. Releases of the alpha branch have been discontinued.

If you were using the alpha release line, you should be able to switch back to the normal release line without issue.

If you were using the normal release line, you should now see several new product lines that were historically hidden from you due to their Beta or Developer Preview status. Such products are explicitly documented as Beta/Developer Preview both in the Twilio docs and console, as well as through in-line code documentation here in the library.


To install using Bundler grab the latest stable version:

gem 'twilio-ruby', '~> 5.19.0'

To manually install twilio-ruby via Rubygems simply gem install:

gem install twilio-ruby -v 5.19.0

To build and install the development branch yourself from the latest source:

git clone
cd twilio-ruby
make install

Getting Started

Setup Work

require 'twilio-ruby'

# put your own credentials here
 = 'ACxxxxxxxxxxxxxxxxxxxxxxxxxxxxx'
auth_token = 'yyyyyyyyyyyyyyyyyyyyyyyyyyyyyyy'

# set up a client to talk to the Twilio REST API
@client = , auth_token

Make a Call

  from: '+14159341234',
  to: '+16105557069',
  url: ''

Send an SMS

  from: '+14159341234',
  to: '+16105557069',
  body: 'Hey there!'

List your SMS Messages


Fetch a single SMS message by Sid

# put the message sid you want to retrieve here:
message_sid = 'SMxxxxxxxxxxxxxxxxxxxxxxxxxxxxx'

Customizing your HTTP Client

twilio-ruby uses Faraday to make HTTP requests. You can tell Twilio::REST::Client to use any of the Faraday adapters like so:

@client.http_client.adapter = :typhoeus

Getting Started With Client Capability Tokens

If you just need to generate a Capability Token for use with Twilio Client, you can do this:

require 'twilio-ruby'

# put your own account credentials here:
 = 'ACxxxxxxxxxxxxxxxxxxxxxxxxxxxxx'
auth_token = 'yyyyyyyyyyyyyyyyyyyyyyyyyyyyyyy'

# set up
capability = , auth_token

# allow outgoing calls to an application
outgoing_scope = 'AP11111111111111111111111111111111'

# allow incoming calls to 'andrew'
incoming_scope = 'andrew'

# generate the token string
@token = capability.to_s

There is a slightly more detailed document in the Capability section of the wiki.

Getting Started With TwiML

You can construct a TwiML response like this:

require 'twilio-ruby'

response = do |r|
  r.say(message: 'hello there', voice: 'alice')
  r.dial(caller_id: '+14159992222') do |d|
    d.client 'jenny'

# print the result
puts response.to_s

This will print the following (except for the whitespace):

<?xml version="1.0" encoding="UTF-8"?>
  <Say voice="alice">hello there</Say>
  <Dial callerId="+14159992222">
