cannot get RTMP URL and stream key

Question

I am developing code using the youtube API for live streaming. What I have done

1. I have registered a project in google and gotten client_id, client_secret, and developer ID
2. I have done OAuth 2.0 and gotten the code and exchanged it to AUTH_TOKEN
3. 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/'
  xmlns:yt='http://gdata.youtube.com/schemas/2007'>

    </entry> 
  </content> 
  <yt:when start='2013-07-05T22:00:00.000Z'/> 
</entry>

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
