create an initializer config rocketchat-notifier.rb to config/initializers/ and add the following content and add your webhook url:

  # config.verbose_mode = true
end

And you are ready to go

Usage

Fire a notification with: RocketChatNotifier.notify "my message"

Optional parameters:

• emoji: set a avatar emoji (:ok:, or :smile: e.g. See http://emoji.codes/ for a quick lookup)
• event: set a eventname (will be shown as "username" in rocket.chat)
• attachment: set an attachment hash. Example:

  {
    "title": "Rocket.Chat",
    "title_link": "https://rocket.chat",
    "text": "Rocket.Chat, the best open source chat",
    "image_url": "https://rocket.chat/images/mockup.png",
    "color": "#764FA5"
  }

Use the optional parameters as named parameters.

Example:

RocketChatNotifier.notify 'my message', emoji: ':ok:', event: 'my notifier', attachment: {title: 'my att. title', text: 'attachment text', color: '#FF0000'}

Additionally you will need a parser script for your rocket.chat for the incoming webhook integration.

If you don't want to code one yourself, here is a working script with basic functionality for you: https://github.com/cbajohr/rocketchat-notifier/wiki/rocket.chat---incoming-webhook-parser-script-example
