Answer 1

The server log shows "Invalid Authenticity Token" message. This means that the token saved by rails server in a previous requests cookie did not match the token sent with your POST request.

If this is the first interaction for this service/server and no previous token is available, you an skip this validation for this particular action (i.e index action)

class FooController < ApplicationController


 protect_from_forgery except: :index
