Question

My facebook integration used to work but for a few days it is not any longer?
As I have read around and found that I need to do a webrequest now to get access_token.
https://graph.facebook.com/oauth/access_token?client_id={0}&redirect_uri=&client_secret={1}&code={2}
The issue is that I don’t receive any response. Have you guys implemented a way how to receive access token?
I use debugger tool from facebook using this request I make and I receive 400 error bad request.
This is the link:
https://graph.facebook.com/oauth/access_token?client_id=234035623293956&redirect_uri=https://www.hotelopro.com/TestFb.aspx&client_secret=38c373c3f3723d793f58cb745c9b0364&code=efa62750b66f1a2207cafdf6.1-100002637731450|qn9fIozBUHBYuNchC_f4HLXFbiI
If it helps you.

Do not use the “official” C# library. The code is outdated and not updated!

Try http://facebooksdk.codeplex.com/ (I worked in C #. NET 4 – everything without problems).
