Status Update Notifications, statusUpdateNotification
I set Subscription Status URL in my APP in iTunes account like https://www.xxxxxx.xx/iospushnotification.php
I also successfully tested nscurl --ats-diagnostics https://www.xxxxxx.xx/iospushnotification.php
I also implemented php code in iospushnotification.php file to get JSON response
I purchased successfully Auto renewal Subscriptions Sandbox but I did not get any Status Update Notifications I get blank [] JSON response from apple server to my server.

if anyone still cares 2 years later, I found a solution, assuming you're using PHP.
from the stackoverflow post Receive JSON POST with PHP we need to do something like this:
$appleData = file_get_contents('php://input');
then try to json_decode($appleData) from there.
(I've never had to do something so weird to get POST data before, but I've mostly used frameworks before; unfortunately, I do not currently have that luxury...)
