Hi,
Like I wrote ; you can use the "short notify url" using a PHP file in the root ; but that method won't load the plugin parameters for you. You still need to read the method from the URL parameters and load his configuration.
The other solution is to not create a "multiple" plugin ; which means that you could just have one single configuration for the plugin in the database ; which make the reading of the configuration easier.
You can use the function "pluginParams($id)".
If you have one single instance ; you can just pass "0" for the $id ; otherwise you need to give the ID of the payment configuration instance.
