Is there any way to post on google plus using public api key. I dont want to go for client id and secret method as that needs user consent and I want to post every activity on goog

Solution 1:

You can not automatically post activities to Google+ (Unless you have a Google Apps for Business account). You can either use moments.insert which can be inserted programmatically, or you have to use the embeddable share button.
