cannot get RTMP URL and stream key - youtube

Question

I am developing code using the youtube API for live streaming. What I have done
I have registered a project in google and gotten client_id, client_secret, and
developer ID
I have done OAuth 2.0 and gotten the code and exchanged it to AUTH_TOKEN
I can create a live event by posting to domain gdata.youtube.com
with request
/feeds/api/users/default/live/events
with header
Authorization: Bearer AUTH_TOKEN
GData-Version: 2
Content-Type: application/atom+xml
X-GData-Key: key=DEV_ID
with content
<?xml version='1.0' encoding='UTF-8'?>
<entry xmlns='http://www.w3.org/2005/Atom'
xmlns:media='http://search.yahoo.com/mrss/'

This returns HTTP code : 201 and my live event is created, but the returned data
does not include STREAM KEY AND RTMP URL. I need these data to start my live
event automatically.
the return data
<?xml version='1.0' encoding='UTF-8'?>

If I manually login youtube and click on my create live event, I can see my
stream key and RTMP URL there. And I can use they to start streaming manually
So my problem is: how can I get STREAM KEY and RTMP URL automatically (by API
request)?
----EDIT----
based on https://developers.google.com/youtube/2.0/developers_guide_protocol_managing_live_events
it said that when I success create/adding an event, youtube will returns url like this
<yt:cdn name='primary'>
<media:content yt:format='19' yt:name='yt-live_SpQXZYILnN0_35'
url='rtmp://rtmp1.youtube.com/videolive?...'/>
</yt:cdn>
but in my case, my returned data doesn't include this line

Answer 1

After do some research, I solved it by sending this request
/feeds/api/users/default/live/events?inline=true
and the youtube returns me RTMP server URL
Thanks all
