The Twilio Ruby Helper Library

The twilio-ruby helper library lets you write Ruby code to make HTTP requests to the Twilio API. If you are interested in migrating to the newer 5.x version of the Twilio Ruby Helper Library from the 4.x version, check out this guide.

This library is open source, so if you find a feature missing or a bug, we encourage you to contribute back to the twilio-ruby project hosted on GitHub.

Install the Library

The easiest way to install twilio-ruby is from RubyGems.

gem install twilio-ruby

Manual Installation

Or, you can clone the source code for twilio-ruby, and install the library from there.

"Permission Denied"

If the command line gives you a big long error message that says Permission Denied in the middle of it, try running the above commands with sudo, ex. sudo gem install twilio-ruby.

Testing your installation

Try sending yourself an SMS message, like this:

require 'twilio-ruby'

account_sid = "ACXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX" # Your Account SID from www.twilio.com/console
auth_token = "your_auth_token"   # Your Auth Token from www.twilio.com/console

@client = Twilio::REST::Client.new account_sid, auth_token
message = @client.messages.create(
    body: "Hello from Ruby",
    to: "+12345678901",    # Replace with your phone number
    from: "+12345678901")  # Replace with your Twilio number

puts message.sid

Using the Gem

Try the Ruby quickstarts and refer to the open source twilio-ruby specific documentation for details about the methods and classes contained in the library.

Handling Exceptions

If the Twilio API returns a 400 or a 500 level HTTP response, the twilio-ruby library will throw a Twilio::REST::RequestError. 400-level errors are normal during API operation (“Invalid number”, “Cannot deliver SMS to that number”, for example) and should be handled appropriately.

require 'twilio-ruby'

account_sid = "{{ account_sid }}" # Your Account SID from www.twilio.com/console
auth_token = "auth_token"   # Your Auth Token from www.twilio.com/console

begin
    @client = Twilio::REST::Client.new account_sid, auth_token
    message = @client.messages.create(
        body: "Hello from Ruby",
        to: "+12345678901",    # Replace with your phone number
        from: "+12345678901")  # Replace with your Twilio number
rescue Twilio::REST::TwilioError => e
    puts e.message
end

More Documentation

If you'd like to learn more about how Twilio works, or for inspiration about what to build, try the Ruby quickstarts.

The Rest API Documentation has examples written in Ruby for every kind of action you could take with the Twilio API. You should start there if you know what you want to do with the Ruby library.

You may also want to refer to the open source twilio-ruby specific documentation for more details about the methods and classes contained in the gem.

Accessing the 4.x Version of the Helper Library

The most recent version of the Ruby Helper Library is not API compatible with the previous 4.x version you may have used in previous Twilio applications. The older version will continue to work, and you will continue to find sample code for this version throughout our documentation. Should you need to install this version you can do so with the following command:

gem install twilio-ruby -v 4.13.0
