Inbound emails using webhook with Mandrill Ruby - ruby

Question

According to the documentation, we should be looking at a parameter called "message", which doesn't not come in. What does come in is a parameter called "mandrill_events".
require 'mail'
class InboxController < ApplicationController
skip_before_filter :verify_authenticity_token, only: :create
def create
mail = Mail.new(params[:message])
....
No dice, but I do see this in the console log when I use the following syntax (note, it's so much JSON that SO has trouble viewing it with formatting):
puts JSON.parse(params[:mandrill_events])

So I am getting a JSON string, but how exactly is the best way to grab the TO, FROM, and SUBJECT?
Update: I just tried the following:
tester = JSON.parse(params[:mandrill_events])
puts tester[:msg][:subject]
#and even this
puts tester["msg"]["subject"]
Did not work. Got an error: **TypeError (no implicit conversion of String into Integer): **

Answer 1

After a day of banging my head, I came up with the solution. By the way, accessing the values directly doesn't work. I had to loop into it.
incomingMail = params[:mandrill_events]
mail_from = "Cannot read From"
mail_originally_to = "Cannot read To"
mail_subject = "No subject"
mail_date = ""
mail_body = "No email body"
if incomingMail != nil
incomingMail = JSON.parse(incomingMail)
incomingMail.each do |item|
mail_from = item["msg"]["from_email"]
mail_originally_to = item["msg"]["headers"]["To"]
mail_subject = item["msg"]["subject"]
mail_date = item["msg"]["headers"]["Date"]
mail_body = item["msg"]["text"]
mail_body_html = item["msg"]["html"]
end
#Confirm
else
puts "Email not sent. Parameter invalid."
end
