Hey Francisco, That Worked!! I had the same issue of missing the last empty
line, followed your method and implemented it in C#. Its working like
charm. I had tried to figure this out using Fiddler and had played around
in OAuth PlayGround too but was getting the same error there. Thanks a ton
again!! This is what I needed an expert advice on where my request was
failing. Thanks again was really struggling with this, I am able to uplad
photos and videos both now. Cheers!! :D
Sorry Ben not using the .net library but if you want I can post my working
C# code written using HttpRequest.
