Re: [YouTube-API] Re: Using C# to retrieve YouTube Insights

Well Jeff, 

has anyone ever used the .Net API to retrieve insights? I'm providing the e-mail address 

and password of the account.  The token is the developer key. 

The Video objects that come back  from the call  

Feed<Video> videoFeed = request.Get<Video>(new Uri(feedUrl));

Do not appear to have any Link collections or lists that can be interrogated.

Is this an omission on the part of the providers of the YouTube .Net interface, or am I doing something 

incorrect? Can you have one of your .NET API developers advise me where to find the Link objects

within the Feed<Video> list? 

Thank you.

ChDev.

Hello,

 I don't have any C# code readily available, but I can tell you what
you're doing wrong. You should not be manually creating YouTube
Insight URLs. You can't do it. You seem to be using your YouTube
authentication token as the value of the "token=" URL parameter, and
sticking your username and password in the URL for good measure, but
that's completely the wrong approach. The Insight URL is uniquely
generated by the API and exposed in an authenticated request for a
video entry by that entry's owner, in a <link> element. This is
explained at

 https://developers.google.com/youtube/2.0/developers_guide_protocol_insight

 Again, you can't manually create the URL. The only time you need to
modify the automatically generated URL at all is if you want to modify
the user_starttime or user_endtime parameters, which is also covered
in the docs.
