module Mandrill::Rails::WebHookProcessor

WebHookProcessor is a module that mixes in Mandrill web hook processing support to a controller in your application.

The controller is expected to be a singlular resource controller. WebHookProcessor provides the :show and :create method implementation.

  1. Create a controller that includes Mandrill::Rails::WebHookProcessor

  2. Direct a GET :show and POST :create route to the controller

  3. Define handlers for each of the event types you want to handle

e.g. in routes.rb:

resource :webhook, :controller => 'webhook', :only => [:show,:create]

e.g. a Webhook controller:

class WebhookController < ApplicationController
  include Mandrill::Rails::WebHookProcessor

  # Command: handle each 'inbound' +event_payload+ from Mandrill
  def handle_inbound(event_payload)
    # do some stuff
  end

  # Define other handlers for each event type required.
  # Possible event types: inbound, send, hard_bounce, soft_bounce, open, click, spam, unsub, or reject
  # def handle_<event_type>(event_payload)
  #   # do some stuff
  # end

end
