The object returned by acceptNotification is a server request incoming from the gateway. The Omnipay core documentation does not suggest any standard ways to acknowledge the notification. At the moment this involves using $request->send() to get a response object, and then $response->acknowledge() to return and acknowledgement and then immediately exit.
Instead, it makes more sense to return a HTTP response that can then be used in the response by the merchant site when it is ready. That response can include a body, headers and a specific HTTP code as appropriate to the state of the request.
