Answer 1

You can dispatch a job by calling static dispatch method on the job class and passing the job's constructor arguments to the dispatch method, like this:
ReProcessShipment::dispatch($single_data->request_data)->delay(2);
Ensure that you are using the Illuminate\Foundation\Bus\Dispatchable trait to be able to call dispatch on the job class, e.g.:
use Illuminate\Foundation\Bus\Dispatchable;
class ProcessPodcast implements ShouldQueue
{
use Dispatchable, ...
If you have a look at the source you'll see that the static dispatch function creates the job for you using the job's parameters, so you don't need to create the job before you dispatch it. This is the source of the dispatch function:
public static function dispatch()
{
return new PendingDispatch(new static(...func_get_args()));
}
So it essentially transforms this:
ReProcessShipment::dispatch($single_data->request_data);
into this:
new PendingDispatch(new ReProcessShipment($single_data->request_data));
