I need to retrieve my allocations from Facebook so that I know how many Notifications I can send out per day.
$allocation = $facebook->api_client->admin_getAllocation('notifications_per_day');
This method supports retrieving a number of different allocations, as shown in Table 9-3.
Table 9-3. Allocations
Number of Notifications your application can send per user per day
Number of requests your application can send per user per day
Number of email messages your application can send to a user per day
Location of the disable message within emails sent by your application (“1” is at the bottom and “2” is the top)
For more information about allocations, see Understanding Allocations.
