[shunyauads]

When using the code below, one signal is sending the notification two times.

OneSignal::setParam('headings', $headings)
                    ->sendNotificationToAll (
                        $body,
                        $url = null,
                        $data = $dataToNotify,
                        $buttons = null,
                        $schedule = null
                    );

Try this one. OneSignal::sendNotificationToAll( 'You message', 'player id', null, null, null, array( "en" => "Custom Header Name" ));
