fabychy

fabychy A ruby client for Facebook Messenger's bot API provided by Robochy.

Installation

Add the gem to your application's Gemfile

gem 'fabychy'

and run the following

$ bundle install

Usage

Create a bot using Facebook Messenger developer portal. Once the registration is complete, copy the Page Access Token to be used by this library.

With your Page Access Token you can use fabychy like the following:

require 'fabychy'

bot = Fabychy::Bot.new('[PAGE ACCESS TOKEN]')

Get User Information

You need to have the USER_ID for the target user and then call the get_user function:

require 'fabychy'

bot = Fabychy::Bot.new('[PAGE ACCESS TOKEN]')
bot.get_user('[USER_ID]')

Sending Messages

With a created bot you can create messages of different types, attach custom keyboards, and pass them to the send_message function as follows:

require 'fabychy'

bot = Fabychy::Bot.new('[PAGE ACCESS TOKEN]')
message = Fabychy::Message.new(
  recipient: {id: [USER_ID] },
  message: {
    text: "hi there"
  },
  notification_type: Fabychy::Notification::REGULAR
)

The following notification types can be used:

Fabychy::Notification::REGULAR
Fabychy::Notification::SILENT_PUSH
Fabychy::Notification::NO_PUSH

DataTypes and Validations

Fabychy provides some light-weight validation of the generated message. However, when there is too much scaffolding it also allows you to pass the hash object instead of an actual element to create your messages. Below is an example:

require 'fabychy/message'

bot = Fabychy::Bot.new('[PAGE ACCESS TOKEN]')
message = Fabychy::Message.new(
  recipient: {id: "1056613714384965"},
  message: Fabychy::DataTypes::MessageBody.new(
    attachment: Fabychy::DataTypes::TemplateAttachment.new(
        payload: Fabychy::DataTypes::GenericTemplatePayload.new(
          elements: [
            Fabychy::DataTypes::GenericElement.new(
                title: 123,
                image_url: "http://wip.org/media/nima-456.jpg",
                subtitle: "This thing is great!",
                buttons: [
                  Fabychy::DataTypes::Button.new(
                    type: "web_url",
                    title: "robochy",
                    url: "http://robochy.com"
                  )
                ]
              ),
            Fabychy::DataTypes::GenericElement.new(
                title: "hello",
                image_url: "http://wip.org/media/nima-456.jpg",
                subtitle: "This thing a second thing great!",
              )
          ]
        )
      )
    )
  )
  bot.send_message(message)

Parsing the Response

In your callback servlet, pass the received request (not the request body) to the Fabychy::ApiResponse.parse function and you will get the hash response back:

class Simple < WEBrick::HTTPServlet::AbstractServlet
  def do_POST(request, response)
    response = Fabychy::ApiResponse.parse(request) # response is of type Hash
  end
end
