            throw new \Magento\Framework\Exception\CouldNotDeleteException(__("Order is Successfully Saved!"));
        }
    }
}

 When i create an order i get orderId empty what should i do i want to trigger my api whenever new order is created from admin or frontend

http://captain-staging.us-east-2.elasticbeanstalk.com/api/v1/order/SaveSourceData?order_id=&customer...

{"error":[{"field":"order_id","message":"The order id field is required."}],"statusCode":false}

Try with EntityId:

    /**
     * @param Observer $observer
     */
    public function execute(Observer $observer)
    {
        /** @var OrderInterface $order */
        $order = $observer->getEvent()->getOrder();
        $orderId = $order->getEntityId();
        echo "<pre>"; print_r($orderId);exit;
    }

 and use $order variable as OrderInterface Object.

Hope it helps!

Now it says 

Client error: `GET http://qareeb-dev.us-east-2.elasticbeanstalk.com/rest/all/V1/orders/22` resulted in a `404 Not Found` response: {"message":"The entity that was requested doesn't exist. Verify the entity and try again."}

I think you are trying to call wrong API, try with  http://qareeb-dev.us-east-2.elasticbeanstalk.com/rest/V1/orders/22`
