无法与与会者一起创建谷歌日历活动

Question

I am using this PHP Google Client Library for creating google calendar events. My requirement is to create a calendar event on the account I created credentials with and also need to create the same event for attendees. This is my code

$credentials = credentials.json';
require '\vendor\autoload.php';

$client = new Google_Client();
$client->setScopes(Google_Service_Calendar::CALENDAR);
$client->setAuthConfig($credentials);

$service = new Google_Service_Calendar($client);

$event = new Google_Service_Calendar_Event(array(
    'summary' => 'Testing for g calender',
    'location' => 'ABC',
    'description' => 'A chance to hear more about Google\'s developer products.',
    'start' => array(
      'dateTime' => '2022-01-05T09:00:00-07:00',
      'timeZone' => 'America/Los_Angeles',
    ),
    'end' => array(
      'dateTime' => '2022-12-28T17:00:00-07:00',
      'timeZone' => 'America/Los_Angeles',
    ),
    'recurrence' => array(
      'RRULE:FREQ=DAILY;COUNT=2'
    ),
    'attendees' => array(
      array('email' => 'attendee1@gmail.com'),
      array('email' => 'attendee2@gmail.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);

The problem is this code only works when i run this without attendees with attendees it is not working and returns me this error

Fatal error: Uncaught Google_Service_Exception: { "error": { "errors": [ { "domain": "calendar", "reason": "forbiddenForServiceAccounts", "message": "Service accounts cannot invite attendees without Domain-Wide Delegation of Authority." } ], "code": 403, "message": "Service accounts cannot invite attendees without Domain-Wide Delegation of Authority." } }

I look for this issue on the internet and find out that i need a G-Suit account in order to enable this Domain Wide Delegation so get the G-Suit account and followed these steps which are mentioned in google documentation.

but still, this does not help me out and I am still unable to activate this Domain Wide Delegation feature on my account. I am still seeing this feature as it is.. ANY HELP !!

Answer 1

Domain wide deligation can only be configured by the google workspace admin. The service account needs to have been created on google cloud console by a user on the domain.

To be 100% clear standard gmail users can't be used for deligation to a service account. Everything must remain within your workspace domain.

Your code also needs to denote the user on your domain the service account should be impersonating

$client->setSubject('redacted@daimto.com);
