How to get order id using "sales_order_place_after" event

sales_order_place_after: This event is dispatched after the order payment is placed.

$order = $observer->getEvent()->getOrder();
$incrementId = $order->getIncrementId();

sales_order_save_after: This event is called every time the order is saved. For eg. Order status changed, invoiced, shipped & credit memo.

$order = $observer->getEvent()->getOrder();
$orderId = $order->getId();

The event sales_order_place_after triggers after payment processed but before the order has been saved to database. Id will be available after order was successfully saved to database. So sales_order_place_after will not give you orderId though you will get order incremental id.

On the other hand, if you use sales_order_save_after, it will be triggered every time the order is saved.

If you like to get order id just after place an order using after plugin for Magento\Sales\Api\OrderManagementInterface::place will be the best option.

        // do something with order object (Interceptor )
