Google+ API Library not found

[Eric]

Hello,
I am trying to connect my Google+ account to my WordPress, but when I try to add the account on SNAP, I receive:

“Google+ API Library not found

Google+ doesn’t have a built-in API for automated posts yet.
The current Google+ API is “Read Only” and can’t be used for posting.

You need to get a special API Library Module to be able to publish your content to Google+.”

Do you have any suggestions, please?

Thanks

Google and Pinterest don’t have free built-in API to make automated posts. You need to obtain a third party libraries to be able to post to Pinterest and Google+

Google+ and Pinterest API libraries along with MultiAccount Edition of the plugin are currently available for purchase for $49 from here: https://www.nextscripts.com/google-plus-automated-posting#getit
