*
* Please do NOT modify the source code directly.
* Instead, use WordPress Hooks/Filters.
*
* For example, if you'd like to add your own custom conditionals, use:
* ``add_filter ("ws_plugin__optimizemember_during_paypal_notify_conditionals", "your_function");``
*
* @package optimizeMember\PayPal
* @since 3.5
*
* @attaches-to ``add_action("init");``
*
* @return null Or exits script execution after handling IPN procesing.
