Twilio Gem

The Twilio gem provides two major pieces of functionality: (1) a Ruby wrapper for the Twilio REST API and (2) response handlers based on the Twilio Markup XML (TwiML).

See for Twilio's API documentation.

For an overview of the Twilio Gem and a sample use case, check out our cached blog entry:

Calling the Twilio REST API

First set your credentials by calling the connect method:

Twilio.connect('my_twilio_sid', 'my_auth_token')

Now call any of the Twilio classes:

Twilio::Call.make('1234567890', '9876543210', '')

Responding to Twilio

When Twilio calls your application URL, your response must use the Twilio Markup XML ( The Twilio gem makes this very easy by providing a Twilio Verb class.

For example, in a Ruby on Rails application, you could do the following inside a controller class:

Twilio::Verb.dial '415-123-4567'

and you can nest multiple verbs inside a block:

verb = { |v|
  v.say "The time is #{}"


sudo gem install twilio -s

If you need to tweak the source code, clone this repository and do a rake build and rake install.
