Having new year holiday in our country at the moment, so I could not test it carefully. However, I think something like below should work:
Code:
require_once JPATH_ADMINISTRATOR . '/components/com_eventbooking/libraries/rad/bootstrap.php';
$data = [
'title' => 'Event Title',
'event_date' => '2022-12-01',
'main_category_id' => 10,
'price' => 100,
'short_description' => 'Short Description Of Event',
'description' => 'Description Of Event',
];
$input = new RADInput($data);
JLoader::register('EventbookingModelEvent', JPATH_ADMINISTRATOR . '/components/com_eventbooking/model/event.php');
/* @var EventbookingModelEvent $model */
$model = RADModel::getTempInstance('Event', 'EventbookingModel');
$model->store($input);
