Answer 1

just remove 'included_segments' => array('All'),
If you fill both of included_segments and include_player_ids, you will send to all selected player ids and also all selected segments. Segment All mean all subscribers.
you can read about other option on official documentation

Answer 2

I need to remove included_segments and web_buttons
both of them not just included_segments , when I try to just remove included_segments it give me error of {"errors":["You must include which players, segments, or tags you wish to send this notification to."]}
also I don't need 'Authorization: Basic XXXXXXXXXXXXXXXXXXXXXXXXXXXXX'.
