Facebook Marketing API connections: exclude people -

so on ads manager under connections, gives choice exclude people used app way avoid showing ads current users.

the marketing api in doc says can set targeting spec: 'app_install_state' can set 'installed' or 'not_installed' , quote facebook

must used in conjunction promoted_object @ adset level

i have tried adding $targeting object adding on adset level. when go view ad set in ad manager on facebook connections part still unchanged.

'name' => 'test ad set', 'billing_event' => 'app_installs', 'optimization_goal' => 'app_installs', 'campaign_status' => "paused", 'daily_budget' => 5000, 'bid_amount' => 10, 'campaign_group_id' => $id, 'targeting' => json_encode($targeting),  $targeting = array(     'geo_locations' => array(         'countries' => array('us'),     ),     'page_types' => array('mobilefeed'),     'user_os' => array('android'),     'app_install_state' => 'not_installed', ); 

also tried moving app_install_state outside of targeting array adset level.

incase don't know talking part on ad manager:
