Getting Started

Setup Work

require 'twilio-ruby'

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

# set up a client to talk to the Twilio REST API
@client = Twilio::REST::Client.new account_sid, auth_token

Use An API Key

require 'twilio-ruby'

# put your own credentials here
account_sid = 'ACxxxxxxxxxxxxxxxxxxxxxxxxxxxxx'
api_key_sid = 'zzzzzzzzzzzzzzzzzzzzzz'
api_key_secret = 'yyyyyyyyyyyyyyyyyyyyyyyyyyyyyyy'

# set up a client to talk to the Twilio REST API using an API Key
@client = Twilio::REST::Client.new api_key_sid, api_key_secret, account_sid

Specify a Region and/or Edge

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

# set up a client to talk to the Twilio REST API over a specific region and edge
@client = Twilio::REST::Client.new account_sid, auth_token, nil, 'au1'
@client.edge = 'sydney'

# you may also specify the region and/or edge after client creation
@client = Twilio::REST::Client.new account_sid, auth_token
@client.region = 'au1'
@client.edge = 'sydney'

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

Enable Debug logging

In order to enable debug logging, pass in a 'logger' instance to the client with the level set to at least 'DEBUG'

@client = Twilio::REST::Client.new account_sid, auth_token
myLogger = Logger.new(STDOUT)
myLogger.level = Logger::DEBUG
@client.logger = myLogger

@client = Twilio::REST::Client.new account_sid, auth_token
myLogger = Logger.new('my_log.log')
myLogger.level = Logger::DEBUG
@client.logger = myLogger

Make a Call

  from: '+14159341234',
  to: '+16105557069',
  url: 'http://example.com'

Send an SMS

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

List your SMS Messages

@client.messages.list(limit: 20)

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

To use a custom HTTP client with this helper library, please see the Twilio documentation.

Handling Errors

  messages = @client.messages.list(limit: 20)
rescue Twilio::REST::RestError => e
  puts e.message

For more descriptive exception types, please see the Twilio documentation.

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:
account_sid = 'ACxxxxxxxxxxxxxxxxxxxxxxxxxxxxx'
auth_token = 'yyyyyyyyyyyyyyyyyyyyyyyyyyyyyyy'

# set up
capability = Twilio::JWT::ClientCapability.new account_sid, auth_token

# allow outgoing calls to an application
outgoing_scope = Twilio::JWT::ClientCapability::OutgoingClientScope.new 'AP11111111111111111111111111111111'

# allow incoming calls to 'andrew'
incoming_scope = Twilio::JWT::ClientCapability::IncomingClientScope.new 'andrew'

# generate the token string
@token = capability.to_s

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

Generating TwiML

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

You can construct a TwiML response like this:

require 'twilio-ruby'

response = Twilio::TwiML::VoiceResponse.new 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">
