Google Analytics PHP API - 错误（403）访问未配置

I have been Googling this for going on hours now. I have followed the Hello Analytics tutorial.

The application runs fine until the user has granted permission from the Google 'consent screen' at which point i receive the following error:

There wan a general error : Error calling GET My url (403) Access Not Configured. Please use Google Developers Console to activate the API for your project.

I have checked in the developer console and Analytics API is enabled and, after reading other posts on this, have added Google+ and Drive access.

NOTE: I am running this application locally and redirecting the redirecting back to 127.0.0.1.

I have added my code below for reference although I think the issue is to do with my google console account and / or running this application locally.

Appreciate any help with this guys. Please let me know if any further information is required.
