Make Post Privacy As Public To Facebook

[Please do not post in all caps – it’s considered yelling – topic modified]

i want to ask how to make the post privacy set to PUBLIC of all post that are made autopost by SNAP to facebook

I am having linked my facebook page with twitter for auto update of post

http://www.facebook.com/twitter

SNAP post on facebook correctly but the same post is not posted to twitter
i checked by manually posting on fb page and it flows to twitter,

so only error seems to be post may not be of public privacy …

HOW TO change privacy to public

https://developers.facebook.com/docs/reference/api/privacy-parameter/

to post a status update visible to a user’s friends, include this in the POST parameters of a Graph API call to /me/feed or a REST API call to stream.publish:

privacy={‘value’:’ALL_FRIENDS’}

is only i get from facebook, but put where ???????
