A Ruby wrapper for the Urban Airship API.

branch: master
README.markdown

Urbanairship is a Ruby library for interacting with the Urban Airship API.

Installation

gem install urbanairship

Note: if you are using Ruby 1.8, you should also install the system_timer gem for more reliable timeout behaviour. See http://ph7spot.com/musings/system-timer for more information.

Configuration

Urbanairship.application_key = 'application-key'
Urbanairship.application_secret = 'application-secret'
Urbanairship.master_secret = 'master-secret'
Urbanairship.logger = Rails.logger
Urbanairship.request_timeout = 5 # default

Usage

Registering a device token

Urbanairship.register_device('DEVICE-TOKEN')

You can also pass an alias, and a set of tags to device registration.

Urbanairship.register_device('DEVICE-TOKEN',
  :alias => 'user-123',
  :tags => ['san-francisco-users']
)

Unregistering a device token

Urbanairship.unregister_device('DEVICE-TOKEN')

Sending a push notification

notification = {
  :schedule_for => [1.hour.from_now],
  :device_tokens => ['DEVICE-TOKEN-ONE', 'DEVICE-TOKEN-TWO'],
  :aps => {:alert => 'You have a new message!', :badge => 1}
}

Urbanairship.push(notification) # =>
# {
#   "scheduled_notifications" => ["https://go.urbanairship.com/api/push/scheduled/123456"]
# }

Using aliases instead of device tokens

notification = {
  :schedule_for => [1.hour.from_now],
  :aliases => ['ALIAS-ONE', 'ALIAS-TWO'],
  :aps => {:alert => 'You have a new message!', :badge => 1}
}

Urbanairship.push(notification) # =>
# {
#   "scheduled_notifications" => ["https://go.urbanairship.com/api/push/scheduled/123456"]
# }

Batching push notification sends

notifications = [
  {
    :schedule_for => [{ :alias => 'deadbeef', :scheduled_time => 1.hour.from_now }],
    :device_tokens => ['DEVICE-TOKEN-ONE', 'DEVICE-TOKEN-TWO'],
    :aps => {:alert => 'You have a new message!', :badge => 1}
  },
  {
    :schedule_for => [3.hours.from_now],
    :device_tokens => ['DEVICE-TOKEN-THREE'],
    :aps => {:alert => 'You have a new message!', :badge => 1}
  }
]

Urbanairship.batch_push(notifications)

Sending broadcast notifications

Urban Airship allows you to send a broadcast notification to all active registered device tokens for your app.

notification = {
  :schedule_for => [1.hour.from_now],
  :aps => {:alert => 'Important announcement!', :badge => 1}
}

Urbanairship.broadcast_push(notification)

Polling the feedback API

The first time you attempt to send a push notification to a device that has uninstalled your app (or has opted-out of notifications), both Apple and Urban Airship will register that token in their feedback API. Urban Airship will prevent further attempted notification sends to that device, but it's a good practice to periodically poll Urban Airship's feedback API and mark those tokens as inactive in your own system as well.

# find all device tokens deactivated in the past 24 hours
Urbanairship.feedback(24.hours.ago) # =>
# [
#   {
#     "marked_inactive_on"=>"2011-06-03 22:53:23",
#     "alias"=>nil,
#     "device_token"=>"DEVICE-TOKEN-ONE"
#   },
#   {
#     "marked_inactive_on"=>"2011-06-03 22:53:23",
#     "alias"=>nil,
#     "device_token"=>"DEVICE-TOKEN-TWO"
#   }
# ]

Deleting scheduled notifications

If you know the alias or id of a scheduled push notification then you can delete it from Urban Airship's queue and it will not be delivered.

Urbanairship.delete_scheduled_push("123456789")
Urbanairship.delete_scheduled_push(123456789)
Urbanairship.delete_scheduled_push(:alias => "deadbeef")

Segments

Urban Airship segments let you send a push notification to a subset of relevant users based on location, time, preferences, and behavior. You can read more about segments in the Urban Airship docs.

notification = {
  :schedule_for => [1.hour.from_now],
  :segments => ['SEGMENT-ID'],
  :ios => {
    :aps => {
      :alert => 'You have a new message!', :badge => 1
    }
  },
  :android => {
    :alert => 'You have a new message!', :badge => 1
  }
}

Urbanairship.push_to_segment(notification)

Creating a segment

Urbanairship.create_segment({
  :display_name => 'segment1',
  :criteria => {:and => [{:tag => 'one'}, {:tag => 'two'}]}
}) # => {}

Listing your segments

Urbanairship.segments # =>
# {
#   "segments" => [
#     {
#      "id" => "abcd-efgh-ijkl",
#      "display_name" => "segment1",
#      "creation_date" => 1360950614201,
#      "modification_date" => 1360950614201
#     }
#   ]
# }

Urbanairship.segment("abcd-efgh-ijkl") # =>
# {
#  "id" => "abcd-efgh-ijkl",
#  "display_name" => "segment1",
#  "creation_date" => 1360950614201,
#  "modification_date" => 1360950614201
# }

Modifying a segment

Note that you must provide both the display name and criteria when updating a segment, even if you are only changing one or the other.

Urbanairship.update_segment('abcd-efgh-ijkl', {
  :display_name => 'segment1',
  :criteria => {:and => [{:tag => 'asdf'}]}
}) # => {}

Deleting a segment

Urbanairship.delete_segment("abcd-efgh-ijkl") # => {}

Getting your device tokens

Urbanairship.device_tokens # =>
# {
#   "device_tokens" => {"device_token"=>"<token>", "active"=>true, "alias"=>"<alias>", "tags"=>[]},
#   "device_tokens_count" => 3,
#   "active_device_tokens_count" => 1
# }

Getting a count of your device tokens

Urbanairship.device_tokens_count # =>
# {
#   "device_tokens_count" => 3,
#   "active_device_tokens_count" => 1
# }

Tags

Urban Airship allows you to create tags and associate them with devices. Then you can easily send a notification to every device matching a certain tag with a single call to the push API.

Creating a tag

Tags must be registered before you can use them.

Urbanairship.add_tag('TAG')

Listing your tags

Urbanairship.tags

Removing a tag

This will remove a tag from your set of registered tags, as well as removing that tag from any devices that are currently using it.

Urbanairship.remove_tag('TAG')

View tags associated with device

Urbanairship.tags_for_device('DEVICE-TOKEN')

Tag a device

Urbanairship.tag_device(:device_token => 'DEVICE-TOKEN', :tag => 'TAG')

You can also tag a device during device registration.

Urbanairship.register_device('DEVICE-TOKEN', :tags => ['san-francisco-users'])

Untag a device

Urbanairship.untag_device(:device_token => 'DEVICE-TOKEN', :tag => 'TAG')

Sending a notification to all devices with a given tag

notification = {
  :tags => ['san-francisco-users'],
  :aps => {:alert => 'Good morning San Francisco!', :badge => 1}
}

Urbanairship.push(notification)

Using Urbanairship with Android

The Urban Airship API extends a subset of their push API to Android devices. You can read more about what is currently supported here, but as of this writing, only registration, aliases, tags, broadcast, individual push, and batch push are supported.

To use this library with Android devices, you can set the provider configuration option to :android:

Urbanairship.provider = :android

Alternatively, you can pass the :provider => :android option to device registration calls if your app uses Urbanairship to send notifications to both Android and iOS devices.

Urbanairship.register_device("DEVICE-TOKEN", :provider => :android)

Note: all other supported actions use the same API endpoints as iOS, so it is not necessary to specify the provider as :android when calling them.

When sending notifications to Android devices, the Urban Airship API expects the following basic structure:

notification = {
  :schedule_for => [1.hour.from_now],
  :apids => ['DEVICE-TOKEN-ONE', 'DEVICE-TOKEN-TWO'],
  :android => {:alert => 'You have a new message!', :extra => {:foo => 'bar'}}
}

Urbanairship.push(notification)

Note: all public library methods will return either an array or a hash, depending on the response from the Urban Airship API. In addition, you can inspect these objects to find out if they were successful or not, and what the http response code from Urban Airship was.

response = Urbanairship.push(payload)
response.success? # => true
response.code # => '200'
response.inspect # => "{\"scheduled_notifications\"=>[\"https://go.urbanairship.com/api/push/scheduled/123456\"]}"

If the call to Urban Airship times out, you'll get a response object with a '503' code.

response = Urbanairship.feedback(1.year.ago)
response.success? # => false
response.code # => '503'
response.inspect # => "{\"error\"=>\"Request timeout\"}"

Instantiating an Urbanairship::Client

Anything you can do directly with the Urbanairship module, you can also do with a Client.

client = Urbanairship::Client.new
client.application_key = 'application-key'
client.application_secret = 'application-secret'
client.register_device('DEVICE-TOKEN')
notification = {
  :schedule_for => [1.hour.from_now],
  :device_tokens => ['DEVICE-TOKEN'],
  :aps => {:alert => 'You have a new message!', :badge => 1}
}

client.push(notification) # =>
# {
#   "scheduled_notifications" => ["https://go.urbanairship.com/api/push/scheduled/123456"]
# }

This can be used to use clients for different Urbanairship applications in a thread-safe manner.
