Access params of post request to my rails app

I am using Sendgrid to send emails from my rails app. Sendgrid send HTTP POST requests back to my app when events occur on the emails that I send - such as when an email is opened.

Sendgrid requires a URL to be provided which post requests are sent to. Mine is

my_domain.com/contact_processor

My routes.

resources :contact_processor

I know I can define a specific route, I used resources however and learned that the post request was looking for a create action.

My terminal shows the params being received.

parameters: {"_json"=>[{"ip"=>"66.249.82.220", 
"sg_event_id"=>"YWRREWM4ZmItMzY4YS00MjY1LWE3YTAtOTI0MzcwNTJhMTBj", 
"sg_message_id"=>"YZ8_123AQzOXoILstbNB4Q.filter0018p1las1.11190.577E6B3116.0", 
"useragent"=>"Mozilla/5.0 (Windows NT 5.1; rv:11.0) Gecko Firefox/11.0 (via 
 ggpht.com GoogleImageProxy)", "event"=>"open", "foo_id"=>"19", 
"email"=>"[email protected]", "timestamp"=>1467905735, 
"bar_id"=>"23"}], "contact_processor"=>{}}

I'm wanting to access the foo_id, bar_id, and event values so as to use them to update attributes of objects within my app.

What appeared to be a fairly simple task has stumped me.

Any help on how to access these and a bit of an explanation as to what I'm dealing with here would be greatly appreciated.

You can access them in the controller action hit by the callback, just like normal.

1.9.3-p551 :024 > params['_json']
 => [{"ip"=>"66.249.82.220", "sg_event_id"=>"YWRREWM4ZmItMzY4YS00MjY1LWE3YTAtOTI0MzcwNTJhMTBj", "sg_message_id"=>"YZ8_123AQzOXoILstbNB4Q.filter0018p1las1.11190.577E6B3116.0", "useragent"=>"Mozilla/5.0 (Windows NT 5.1; rv:11.0) Gecko Firefox/11.0 (via \n ggpht.com GoogleImageProxy)", "event"=>"open", "foo_id"=>"19", "email"=>"[email protected]", "timestamp"=>1467905735, "bar_id"=>"23"}] 
1.9.3-p551 :025 > params['_json'].first['ip']
 => "66.249.82.220"
