if anyone knows how I can publish something on google + using PHP. I used Google plus Domains API, but it only give access for read. If I can do it by g suite please tell me how can I do it.
//add code
$client = new \Google_Client();
$client>setAccessToken(unserialize(get_option('google_access_token')));
$plus = new \Google_Service_Plus($client);
$plusDomain = new \Google_Service_PlusDomains($client);
$activity = new \Google_Service_PlusDomains_Activity();
$obj = new \Google_Service_PlusDomains_ActivityObject();
try{
$userId = $plusDomain->people->get('me')->id;
$obj->setContent("Test text");
$obj->setActor($userId);
$activity->setObject($obj);
$activity->setActor($userId);
$activity->setTitle("title");
$plusDomain->insert($userId,$activity);
on line setActor my code not continue http://i.prntscr.com/yM7xybRnTzy8H97jY7DKCg.png
There are two different APIs, and your question appears to be combining them. The Google+ api used grants read only access to the Google+ social media website. The Google plus domains api which gives you access to post to your Google plus domains account (gsuite).
You say you want to post to Google+ assuming that you mean the social media website then the answer is you cant the Google+ api as already stated is read only.
Your code appears to be using the Google+ domains api which you need to make sure that the user you are authenticating with has access to a google+ domains account if its not working have the Admin check the users access to the domain account
