Google Plus Login via JavaScript

I could not see any documentation for Google+ Oauth login like FB and Twitter. Is this feature available?
But I do see API key setting options available in the Backendless social setting.

I noticed there were some lines of code for G+ login in the .js file. Can we have some documentation for the same with examples?

Try use Code Generation tab -> JavaScript. There you can find examples for “Registration and Login”.

Works great. Could be better if they are part of the docs section.

It will be added. We are constantly working on improving the documentation, thank you.
