Error when I'm trying to charge in Laravel Cashier Paddle

Question

Paddle API error 'Invalid request.' occurred with validation errors ([{"field":"items.0","message":"Additional property webhook is not allowed"}])

The line is

$checkout = $user->charge('70','pro_01jant018pa45vyq1mqyf9ezye',[
    'webhook'=>'ntfset_01jap2sc8enw41rfkncjwh0ka2']);
