How does ShoppingHelper get built?

Walmart API: The Walmart API is used to get the item information to give user recommendations of related products. The API will return the information in JSON format. ShoppingHelper will fetch product's name, price, and product link and give them to the user.

HTTParty gem: When Walmart API is used, it will respond the information based on a URL request. Therefore, the HTTParty gem is used to get the information from the URL. 

Slack-ruby-client gem: As ShoppingHelper is a slack bot, the slack-ruby-client gem is used in order to make ShoppingHelper talk to the user via Slack.
