SOLVED: Snippet adds user to group, but needs to flush permissions?#

Hi,

I've created a snippet that adds a user to a member group upon successful payment though paypal. Works great. However, as far as I can tell, I have to flush all permissions in the manager to get the paid content to show up for the user.

Is there a way to flush the permissions for a user via the api? I've been trying to sift through how the menu action does it but not having much luck.

Thanks.

solved. when the user returns to the page that lists all resources they have access to, i run a snippet that contains;

$modx->user->getAttributes(array(), '', true);
