I have many subscription in Auth.net all the subscription works as the 30 day time duration and that all the run for the 60 months.
I have several operation such as the email and update my db related and amount change kind of many operation I have to perform when any subscription is made.
Currently I am made it for cron job but there was very long and complex process to do code.
So research on that I found the auth.net something use like the Silent post url.
but I have tried in my sandbox account but it not works. and I am not sure about that this is works when subscription deduct money on the card?
What is silent post url and it's works or not ?
I am posting an answer on basis of the comments and research.
IPN and silent post URL are same things.

This kind of the post name you can get in the your silent post file.
description for test:-
there you can print the data how you receive and get name of the post data.
echo "<pre>";
print_r($_REQUEST);
echo "</pre>";
die();
print array and see the testing data.
Hope that answer will help to understand silent post url.
Thanks.
