Gridhook

Gridhook is a Rails engine providing an endpoint for handling incoming SendGrid webhook events.

This engine supports both batched and non-batched events from SendGrid.

Looking to handle incoming email from the SendGrid Parse API? Gridhook will eventually support that, until then, you should check out Griddler. It's awesome.

Installation

Add Gridhook to your application's Gemfile and run bundle install:

gem 'gridhook'

You must also tell Gridhook how to process your event. Simply add an initializer in config/initializers/gridhook.rb:

Gridhook.configure do |config|
  # The path we want to receive events
  config.event_receive_path = '/sendgrid/event'

  config.event_processor = proc do |event|
    # event is a Gridhook::Event object
    EmailEvent.create! event.attributes
  end
end

The config.event_processor just needs to be any object that responds to call(). So, if you'd prefer to use a separate class, that's fine:

class EventProcessor
  def call(event)
    # do some stuff with my event!
  end
end

# config/initializers/gridhook.rb
Gridhook.configure do |config|
  config.event_processor = EventProcessor.new
end

Changelog
