-### State
-
-> *unique string to be passed back upon completion*

-
-`https://www.yourapp.com/users/auth/slack?state=1234-foobutter`
-
-creates an auth session with `state`
-
-After a successful auth, the callback request will include `request.env["omniauth.params"]` hash
-
-```ruby
-class CallbackController < ApplicationController
-  def slack
-    request.env["omniauth.params"]["state"]
-    # => "1234-foobutter"
-  end
-end
-```
