Check out this Ruby gem that I created for connecting with Watson Assistant chatbots. Once installed, you can exercise the dialogs that use the intents and entities in your Watson Assistant workspace or skill with just a few lines of code.

Using the Ruby gem

First, install the Ruby gem:

gem install watson-assistant-chatbot

Next, create your chatbot instance, connect it with your Watson Assistant workspace by specifying the user_id, password, workspace_id, and optionally, api_version, and start having a conversation:

require 'watson-assistant-chatbot'
require 'json'

WatsonAssistant::Chatbot.api_version = '2018-02-16'

chatbot = WatsonAssistant::Chatbot.new('<user_id>', '<password>', '<workspace_id>')

request = { "input" => { "text" => "hello" } }

puts chatbot.message(request.to_json)

You can use this gem to quickly add a cognitive chatbot to your Rails or Sinatra web applications.

Get the Ruby source code of the gem from Github.
