Compensation

Compensation is saga rollback. When step N fails, laravel-flow walks previously completed compensatable steps from N - 1 back to the first step and calls each FlowCompensator.

Flow::define('order.fulfill')
    ->withInput(['order_id'])
    ->step('reserve_stock', ReserveStock::class)
        ->compensateWith(ReleaseStock::class)
    ->step('capture_payment', CapturePayment::class)
        ->compensateWith(RefundPayment::class)
    ->step('ship', CreateShipment::class)
        ->compensateWith(CancelShipment::class)
    ->register();
