Can't configure tracker integration

[vsanta]

Maybe we're doing something wrong but we're getting 404 on the validation.

Note: I changed my API after this screenshot :)

Slightly different error here. On the browser console, I see all calls returns a 202, not a 404.
Those calls are not to a pivotal tracker address, but to the current app (the project monitor app itself).
Is that correct? I see that the route is defined in routes.rb:

  post 'projects/validate_tracker_project'

but -being not familiar with ruby at all- I can't see in the code where the call to the actual pivotal tracker url is made... if I make a POST to http://pulse.pivotallabs.com/projects/validate_tracker_project (the URL in your screenshot) I just get a login page... my pivotal tracker login doesn't work.

When I look at the project monitor application logs, I see:

Seems it can't find the project.. but the request contains the id, the pproject_id and the auth_token, and in can see a project with that id in the project monitor db...
