API post an event

[BulliM]

How to post an event by vBulletin API? What do I have to define, if I want to post automatically as event? My code so far:

$input = array(
	'hvinput'  => '',
	'title'  => 'Title of new event post',
	'rawtext' => 'HTML content of new event post',
	'parentid' => 10,
	'channelid' => 10,
	'nl2br' => false,
	'htmlstate' => 'on',
	'disable_bbcode' => true,
	'tags' => 'post,newpost'
);
		
$options = array(
	'skipDupCheck' => true
);
		
$nodeId = $api->callApi('content_text', 'add', array($input, $options));
