are you getting your key from the google api console?, if you are are you enabling all maps api’s that are included in your app? java script api being one of them? have you tried adding your api key in your apps Settings > General tab?
I don’t know what to say… I went to general tab in my app settings. Two key where added, I just delete them because i wasn’t sure about their availability and… it works ! strange… but honestly I am just happy ! thank you very much
depending on your setup in the IAMADMIN console you can either add a secret to your calls to the api to make sure no one uses your keys and also set the referrer url (your app) so calls must come from that url…
