SmsKit

Easily send text messages via an HTTP SMS gateway.
The goal is to offer one streamlined API for any provider adapter.

Installation

Add this line to your application's Gemfile:

gem 'sms_kit'

And then execute:

$ bundle

Or install it yourself as:

$ gem install sms_kit

Usage

Configuration

You can store arbitrary options in a provider's configuration:

require 'sms_kit/providers/mobi_web'
SmsKit::MobiWeb.configure do |config|
  config.username = 'user'
  config.password = 'pass'
  config.sender   = 123456
end

Send text message

provider = SmsKit::MobiWeb.new text: 'Hello World.', to: 491231234567
result   = provider.deliver

# returns the message id from MobiWeb or nil if something went wrong
puts result // 1234

There's also a short version:

SmsKit::MobiWeb.deliver text: 'Hello World.', to: 491231234567

Sending "Objects"

If your class responds to to_sms, you can send it itself:

class TextMessage
  def to_sms
    {
      to: 491231234567
      text: 'hello world'
    }
  end
end

SmsKit.deliver :provider_name, TextMessage.new

# or on a provider level

class MyProvider < SmsKit::Provider
  # ...
end

MyProvider.deliver TextMessage.new

Custom Provider

class MyProvider < SmsKit::Provider
  # default url that the built-in http client will use
  HTTP_ENDPOINT = 'https://www.example.com'.freeze

  # ...

  # custom connection configuration
  # the default implementation (`super`) accepts a block
  # which yields you a faraday instance
  def connection
    super do |conn|
      conn.headers[:user_agent] = 'custom user agent'
    end
  end
end

Error handling

SmsKit will throw a SmsKit::DeliveryError if something goes wrong. Though it depends on the specific provider this generally happens upon authentication errors as well as returned error codes from the web service.

begin
  provider = :provider_symbol
  SmsKit.deliver provider, text: 'hello world', to: '...'
rescue SmsKit::DeliveryError => e
  logger.error e
end

Common SMS options

Which options the #deliver method expects generallly depends on provider implementation. However, core providers expect the following options, at least:

• :to The number to send the message to
• :from The sender ID
• :text The text message
