## Documentation

The documentation for the Twilio API can be found [here][apidocs].

The Ruby library documentation can be found [here][libdocs] and individual releases [here][refdocs].

## Versions

`twilio-ruby` uses a modified version of [Semantic Versioning](https://semver.org) for all changes. [See this document](VERSIONS.md) for details.

### Supported Ruby Versions

This library supports the following Ruby implementations:

* Ruby 2.4
* Ruby 2.5
* Ruby 2.6
* Ruby 2.7
* Ruby 3.0
* Ruby 3.1

### Migrating from 4.x

[Upgrade Guide][upgrade]

## Installation

To install using [Bundler][bundler] grab the latest stable version:

```ruby
gem 'twilio-ruby', '~> 5.67.3'
```

To manually install `twilio-ruby` via [Rubygems][rubygems] simply gem install:

```bash
gem install twilio-ruby -v 5.67.3
```

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

```bash
git clone git@github.com:twilio/twilio-ruby.git
cd twilio-ruby
make install
```

## Getting Started

### Setup Work

```ruby
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

```ruby
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](https://www.twilio.com/docs/global-infrastructure), specify the target Region and/or Edge for the client:

```ruby
# 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'

```ruby
@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

```ruby
@client.calls.create(
  from: '+14159341234',
  to: '+16105557069',
  url: 'http://example.com'
)
```

### Send an SMS

```ruby
@client.messages.create(
  from: '+14159341234',
  to: '+16105557069',
  body: 'Hey there!'
)
```

### List your SMS Messages

```ruby
@client.messages.list(limit: 20)
```

### Fetch a single SMS message by Sid

```ruby
# put the message sid you want to retrieve here:
message_sid = 'SMxxxxxxxxxxxxxxxxxxxxxxxxxxxxx'
@client.messages(message_sid).fetch
```

### Customizing your HTTP Client

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

```ruby
@client.http_client.adapter = :typhoeus
```

To use a custom HTTP client with this helper library, please see the [Twilio documentation](https://www.twilio.com/docs/libraries/ruby/custom-http-clients).

To apply customizations such as middleware, you can use the `configure_connection` method like so:

```ruby
@client.http_client.configure_connection do |faraday|
  faraday.use SomeMiddleware
end
```

### Handling Errors

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

For more descriptive exception types, please see the [Twilio documentation](https://www.twilio.com/docs/libraries/ruby/usage-guide#error-handling).

### Getting Started With Client Capability Tokens

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

```ruby
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'
capability.add_scope(outgoing_scope)

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

# generate the token string
@token = capability.to_s
```

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

### Generating TwiML

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

You can construct a TwiML response like this:

```ruby
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'
  end
end

# print the result
puts response.to_s
```

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

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

## Docker Image

The `Dockerfile` present in this repository and its respective `twilio/twilio-ruby` Docker image are currently used by Twilio for testing purposes only.
