Google_Service_Calendar_Channel requires that you send a client to authenticate it. Personally i would use service account.
function getServiceAccountClient() {
try {
// Create and configure a new client object.
$client = new Google_Client();
$client->useApplicationDefaultCredentials();
$client->addScope('https://www.googleapis.com/auth/calendar');
return $client;
} catch (Exception $e) {
print "An error occurred: " . $e->getMessage();
}
}
$client = getServiceAccountClient();
$channel = new Google_Service_Calendar_Channel($client);
$channel->setId($channelId);
$channel->setType("web_hook");
$channel->setAddress("https://example.com/notifications");
$service->events->watch($calendarId, $channel);
I've added the client in the channel creation like this:
$channel = new Google_Service_Calendar_Channel($googleCalendar->getClient());But I still get the same errorAppears I had to create a OAuth2 client ID on the Google Developer Console, and then use that to authenticate my app. After that, using the client made it works perfectly, thanks for the help!
