+# This controller is designed to allow your Agents to receive cross-site Webhooks (posts).  When POSTed, your Agent will
2 
+# have #receive_webhook called on itself with the POST params.
3 
+#
4 
+# Make POSTs to the following URL:
5 
+#   http://yourserver.com/users/:user_id/webhooks/:agent_id/:secret
6 
+# where :user_id is your User's id, :agent_id is an Agent's id, and :secret is a token that should be
7 
+# user-specifiable in your Agent.  It is highly recommended that you verify this token whenever #receive_webhook
8 
+# is called.  For example, one of your Agent's options could be :secret and you could compare this value
9 
+# to params[:secret] whenever #receive_webhook is called on your Agent, rejecting invalid requests.
10 
+#
11 
+# Your Agent's #receive_webhook method should return an Array of [json_or_string_response, status_code].  For example:
12 
+#   [{status: "success"}, 200]
13 
+# or
14 
+#   ["not found", 404]
