Triggering custom code after Task Move (from/to any column)

[cloter]

Hi,
Just as the title says, I need to make an API call to another server after a task moves from/to any column on the panel. Per tutorials, I built basic plugin code, but I don't seem to understand how to get the data from the $event object. I can trigger the event based on task move:

  public function initialize() {
    // Listen to the event when a task moves between columns
    $this->on('task.move.column', 'Kanboard\Plugin\ColumnChangeAPI\Listener::onTaskMove');
  }

and my code has:

class Listener extends Base {
    public static function onTaskMove($event) { 
        $task = $event['task'];
        $project = $event['project']; 
        ...

I need to extract 'task_id' and 'project_id' and present column info from $event, but I failed over and over on this.

Could anyone pls point me at the right direction?

Tkanks
