I really hate it, but this is offcourse a newbie question:
I'm in search how I must implement the api.

If I go to:
https://console.developers.google.com/apis/dashboard?pli=1

what kind of api do I need ? I think I need the maps javascript api ?
https://console.developers.google.com/google/maps-apis/apis/maps-backend.googleapis.com/metrics?project=xxx

When I click on inloggegevens, the wheel of google is thurning, but there is nothing hapening. I don't understand it. I left it turning overnight. Seems like a bug on the google developers website ?
