Google calender API Service account

Question

There are hundreds of examaple files for Google Calendar API and I have been stuck a couple of days now and i'm getting a lot of errors. I downloaded the https://github.com/google/google-api-php-client/releases/tag/v2.0.3 lib and tried to add a event in my Google Calendar. It would be great if you could give us an up to date solution for us newbies here on stackoverflow. The code is running on hostinger.com and the files is in the same dir.

Is there any up to date ready to use example that creates events? Like new version of this.

Isn't client_secret.json' same as '/calendar-php-quickstart.json'?

<?php
require_once __DIR__ . '/vendor/autoload.php';


define('APPLICATION_NAME', 'Google Calendar API PHP Quickstart');
define('CREDENTIALS_PATH', '/calendar-php-quickstart.json');
define('CLIENT_SECRET_PATH', __DIR__ . '/client_secret.json');
// If modifying these scopes, delete your previously saved credentials
// at ~/.credentials/calendar-php-quickstart.json
define('SCOPES', implode(' ', array(
 Google_Service_Calendar::CALENDAR_READONLY)
));

 if (php_sapi_name() != 'cli') {
  throw new Exception('This application must be run on the command line.');
 }

/**

* @return Google_Client the authorized client object
*/
function getClient() {
$client = new Google_Client();
$client->setApplicationName(APPLICATION_NAME);
$client->setScopes(SCOPES);
$client->setAuthConfig(CLIENT_SECRET_PATH);
$client->setAccessType('offline');

 // Load previously authorized credentials from a file.
 $credentialsPath = expandHomeDirectory(CREDENTIALS_PATH);
 if (file_exists($credentialsPath)) {
  $accessToken = json_decode(file_get_contents($credentialsPath), true);
 } else {
// Request authorization from the user.
$authUrl = $client->createAuthUrl();
printf("Open the following link in your browser:\n%s\n", $authUrl);
print 'Enter verification code: ';
$authCode = trim(fgets(STDIN));

// Exchange authorization code for an access token.
$accessToken = $client->fetchAccessTokenWithAuthCode($authCode);

   // Store the credentials to disk.
   if(!file_exists(dirname($credentialsPath))) {
  mkdir(dirname($credentialsPath), 0700, true);
  }
  file_put_contents($credentialsPath, json_encode($accessToken));
  printf("Credentials saved to %s\n", $credentialsPath);
  }
  $client->setAccessToken($accessToken);

  // Refresh the token if it's expired.
 if ($client->isAccessTokenExpired()) {
$client->fetchAccessTokenWithRefreshToken($client->getRefreshToken());
file_put_contents($credentialsPath, json_encode($client->getAccessToken()));
 }
 return $client;
}

// Get the API client and construct the service object.

Answer 1

This is the example Google gives for php inserting a calendar event in v3:

Note that for v3 you must use OAuth 2.0, but the best way to do that is with the google-api-php-client using this example called "idtoken"

// Refer to the PHP quickstart on how to setup the environment:
// https://developers.google.com/google-apps/calendar/quickstart/php
// Change the scope to Google_Service_Calendar::CALENDAR and delete any stored
// credentials.

$event = new Google_Service_Calendar_Event(array(
  'summary' => 'Google I/O 2015',
  'location' => '800 Howard St., San Francisco, CA 94103',
  'description' => 'A chance to hear more about Google\'s developer products.',
  'start' => array(
    'dateTime' => '2015-05-28T09:00:00-07:00',
    'timeZone' => 'America/Los_Angeles',
  ),
  'end' => array(
    'dateTime' => '2015-05-28T17:00:00-07:00',
    'timeZone' => 'America/Los_Angeles',
  ),
  'recurrence' => array(
    'RRULE:FREQ=DAILY;COUNT=2'
  ),
  'attendees' => array(
    array('email' => 'lpage@example.com'),
    array('email' => 'sbrin@example.com'),
  ),
  'reminders' => array(
    'useDefault' => FALSE,
    'overrides' => array(
      array('method' => 'email', 'minutes' => 24 * 60),
      array('method' => 'popup', 'minutes' => 10),
    ),
  ),
));

$calendarId = 'primary';
$event = $service->events->insert($calendarId, $event);
printf('Event created: %s\n', $event->htmlLink);
