This is sample code for a CreateRequest object. I don't know exactly what this is supposed to do, so I'm going to make this up as I go. Hopefully it is helpful to show multiple jacks on one action.

create_request.rb

class CreateRequest

  def initialize request_jack, notification_jack, payment_jack
    @request_jack = request_jack
    @notification_jack = notification_jack
    @payment_jack = payment_jack
  end
  
  def execute input
    unless input.has_shape? user_id: Fixnum, text: String, amount: Float, who_to_notify: Fixnum
      raise ArgumentError.new 'invalid input format'
    end
    
    # Create a Request entity an save it to some jack (so, DB)
    data = { user_id: input[:user_id], text: input[:text] }
    request = Request.new
    request.populate data
    request_data = @request_jack.save request.to_hash #returns a hash of the request data persisted
    
    # Notify some one that a new Request exists (so, let's say email...also might create a notification object)
    data = { who_to_notify: input[:who_to_notify], user_id: request_data[:user_id], text: request_data[:text] }
    notification = Notification.new
    notification.populate data
    notification_data = @notification_jack.push notification.to_hash
    
    
    # Handle payment for the Request (so, some payment processor stuff)
    data = { amount: input[:amount], user_id: input[:user_id] }
    payment = Payment.new
    payment.populate data
    payment_data = @payment_jack.purchase payment.to_hash
    
    # I don't know what you want to return here, so return everything I guess
    { request_info: request_data, notification_info: notification_data, payment_info: payment_data } 
  end

end
