Fast & Smart Push Notification Service

Last updated October 09, 2019

Pushwoosh is a real-time cross-platform push notification service. The Pushwoosh add-on allows you to engage your audience effectively by sending unlimited push notifications to websites and mobile apps.

Provisioning the add-on

Pushwoosh can be attached to a Heroku application via the CLI:

$ heroku addons:create pushwoosh

Once the add-on has been attached to your app, the Pushwoosh account will be automatically created for you. The account allows you to send unlimited pushes and use API access. The API token will be created and saved in the PUSHWOOSH_API_TOKEN config var.

Once the Pushwoosh account has been created, your application will be automatically added to the Pushwoosh control panel. The application code will be created and saved in the PUSHWOOSH_APPLICATION_CODE config var.

The configuration variable PUSHWOOSH_API_TOKEN can be confirmed using the heroku config:get command.

$ heroku config:get PUSHWOOSH_API_TOKEN

Client side integration

Our SDKs allow you to seamlessly integrate the Pushwoosh service into your app or your website regardless of the platform you’re using.

Sending API requests

Use /createMessage to send requests via the Pushwoosh API. Replace API_TOKEN with one of the following code samples, depending on the programming language you use.

Ruby

ENV['PUSHWOOSH_API_TOKEN']

PHP

$_ENV['PUSHWOOSH_API_TOKEN']

Python

os.environ['PUSHWOOSH_API_TOKEN']

Java

System.getenv("PUSHWOOHS_API_TOKEN")

Golang

os.Getenv("PUSHWOOSH_API_TOKEN")

Use with Ruby

  #     - PushNotification.new.notify_devices(notification_options = {}) Notifies specific devices with custom options

                        #:devices  => {}
                      }

    #- Merging with specific options
    final_notification_options = default_notification_options.merge(notification_options)

    #- Constructing the final call
    options = @auth.merge({:notifications  => [final_notification_options]})
    options = {:request  => options}
    #- Executing the POST API Call with HTTPARTY - :body => options.to_json allows us to send the json as an object instead of a string
    response = self.class.post("https://cp.pushwoosh.com/json/1.3/createMessage", :body  => options.to_json,:headers => { 'Content-Type' => 'application/json' })
  end
