action_sms

action_sms allows you to switch between SMS Gateways effortlessly without modifying your application or test code. By keeping SMS Gateway configuration out of your code you can be more adaptable to change.

Current SMS Gateway Adapters

Adapter Specific Configuration

Usage

Configuration

Establish a connection to your SMS Gateway Adapter:

ActionSms::Base.establish_connection(
  :adapter => 'your_adapter',
  # the remaining options are specific to the SMS Gateway Adapter
  :username => 'username',
  :password => 'password'
)

The only required option is :adapter. This specifies the SMS Gateway adapter you want to use. The remaining options are specific to the adapter.

Send an SMS and check if it was successful

class SMS
  def recipient
    "617198378843"
  end

  def body
    "Hello world"
  end

  def from
  end
end

response = ActionSms::Base.deliver(SMS.new)
success = ActionSms::Base.delivery_request_successful?(response)

Receive an SMS

# Assume 'params' has the data posted back to your server

# get sender
sender = ActionSms::Base.sender(params)

# get message text
message_text = ActionSms::Base.message_text(params)

Delivery receipts

# Assume 'receipt' has the data posted back to your server as the delivery receipt

# get status
status = ActionSms::Base.status(receipt)

# get message id
message_id = ActionSms::Base.message_id(receipt)

Authentication

ActionSms::Base.establish_connection(
  :authentication_key => "my secret",
  :use_ssl => true
)

If you set up an: authentication_key in the configuration, your key will be passed back to your listener url. Using an authentication key in conjunction with a secure connection use_ssl => true helps protect you against someone faking incoming messages to your server. You can authenticate an incoming message as follows:

# Assume 'params' has the data posted back to your server

# Removes the authentication key from 'params' and returns true or false
ActionSms::Base.authenticate(params)

Service url

# gets the gateway's api url
# ActionSms::Base.service_url

Testing

When you set: :environment => "test" in your configuration, you get some additional test helpers.

ActionSms::Base.establish_connection(
  :environment => "test"
)

# get sample configuration
ActionSms::Base.sample_configuration

# get sample incoming SMS params
ActionSms::Base.sample_incoming_sms

# get customized sample incoming SMS
ActionSms::Base.sample_incoming_sms(
  :message => "hello",
  :to => "6128392323",
  :from => "61289339432",
  :date => Time.now,
  :authentic => false     # see configuration
)

# get sample delivery response
ActionSms::Base.sample_delivery_response

# get sample delivery response (failed)
ActionSms::Base.sample_delivery_response(:failed => true)

# get a sample delivery response with a message id
ActionSms::Base.sample_delivery_response_with_message_id("12345")

# get sample message id
ActionSms::Base.sample_message_id

# get sample delivery receipt
ActionSms::Base.sample_delivery_receipt

# get customized sample delivery receipt
ActionSms::Base.sample_delivery_receipt(
  :message_id => "12345",
  :status => "delivered",
  :error => "some error",
  :date => Time.now
)

Creating your own adapter

To create your own adapter all you need to do is open up the ActionSms::Base class and add a class method named: my_adapter_connection which takes a single hash argument of configuration details and returns an instance of your adapter class. For example, let's create an adapter for clickatell:

# clickatell_adapter.rb
require 'action_sms/connection_adapters/abstract_adapter'

module ActionSms
  class Base
    def self.clickatell_connection(config)
      ConnectionAdapters::ClickatellAdapter.new(config)
    end
  end
end

module ConnectionAdapters
  class ClickatellAdapter < AbstractAdapter
    # define your adapter here ...
    def initialize(config)
    end
  end
end

Rails

For convenience there is a generator that can be used if you are using action_sms within a Rails app

rails g action_sms:initializer

Generates an initializer including example configuration for built-in adapters
