Google+ API, call API without access token - node.js

Question

I implemented a Google+ and a Facebook login button and got access token successfully. However I didn't save it in my server. For new business, I need to get display name and image of authorized users.
For Facebook integration, I can use :
https://graph.facebook.com/userId?fields=picture.width(720).height(720),name&access_token=APP_ID|APP_SECRET
Are there any similar way for Google+ API to get public information of Google+ user (image, name, email..) without the missing access token?

Answer 1

Google has something called a public API key. Public API keys can only be used to access Public data. So if the user in question hasn't set something on there profile public you wont be able to see it.
You will need to go to google developer console an register your application there you will be able to create a public key and enable the google+ api.
