I need to do a request with XML API.
POST /feeds/api/videos/VIDEO_ID/comments HTTP/1.1
Host: gdata.youtube.com
Content-Type: application/atom+xml
Content-Length: CONTENT_LENGTH
Authorization: Bearer ACCESS_TOKEN
GData-Version: 2
X-GData-Key: key=DEVELOPER_KEY
<?xml version="1.0" encoding="UTF-8"?>
<entry xmlns="http://www.w3.org/2005/Atom"
xmlns:yt="http://gdata.youtube.com/schemas/2007">
<content>This is a crazy video.</content>
</entry>
What should I use for this?
