Insert Moment in Google+ using Google PHP Client - php

Question

I'm trying to insert some activity app in a Google+ profile as shown in this documentation page:
https://developers.google.com/+/api/latest/moments/insert
I successfully obtain the access token needed, but seems the moments->insert method doesn't make anything.
If successful I would expect to see something on this page, once made the access, but nothing happen
https://plus.google.com/u/0/apps/activities
That's my code
<?php
require_once '../google-api-php-client/Google_Client.php';
require_once '../google-api-php-client/contrib/Google_PlusService.php';
session_start();
$client = new Google_Client();
$client->setClientId('xxxxxxxxxxxx-xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx.apps.googleusercontent.com');
$client->setClientSecret('xxxxxxxxxxxxxxxxxxxxxxxx');
$client->setRedirectUri('http://www.myregisteredcallbackurl.com');
$client->setAccessType('offline');
$client->setScopes(array('https://www.googleapis.com/auth/plus.login'));
$client->setApprovalPrompt('force');
$plus = new Google_PlusService($client);
if (isset($_GET['logout'])) {
unset($_SESSION['token']);
}
if (isset($_GET['code'])) {
$client->authenticate($_GET['code']);
$_SESSION['token'] = $client->getAccessToken();
header('Location: http://' . $_SERVER['HTTP_HOST'] . $_SERVER['PHP_SELF']);
}
if (isset($_SESSION['token'])) {
echo 'Logout<br><br>'.PHP_EOL.PHP_EOL;
$client->setAccessToken($_SESSION['token']);
$moment = new Google_Moment();
$moment->setType('http://schemas.google.com/AddActivity');
$itemScope = new Google_ItemScope();
$itemScope->setUrl('https://developers.google.com/+/plugins/snippet/examples/thing');
$moment->setTarget($itemScope);
$plus->moments->insert('me', 'vault', $moment);
}
if ($client->getAccessToken()) {
$_SESSION['token'] = $client->getAccessToken();
} else {
$authUrl = $client->createAuthUrl();
echo 'Connect<br>';
}

You need to add the requestvisibleactions permissions to your scope. The easiest way to do this is to switch from the conventional OAuth 2.0 flow to the new Google+ Sign-In flow - the Google+ team provides a PHP sample for Google+ Sign-In. If you want to continue using the older OAuth flow, you need to append request_visible_actions=[the app activity types] to your authorization URL.

In your code, you are really close, the following seems to work for me:
$client = new Google_Client();
$client->setClientId('YOUR_CLIENT_ID');
$client->setClientSecret('YOUR_CLIENT_SECRET');
$client->setRedirectUri('http://example.com/callback.php');
$client->setAccessType('offline');
$client->setScopes(array('https://www.googleapis.com/auth/plus.login'));
$client->setRequestVisibleActions(array('https://schemas.google.com/AddActivity'));
$plus = new Google_PlusService($client);
To check the app activities that you have written, visit the app activity log.
