Hi Georgina, Everything appears correct with your base string for this step.
Are you performing this operation through a HTTP proxy of any kind? Have you tried producing a valid OAuth header and executed it in curl (without having "executed it" in C# first)? I'm not familiar with C#'s HTTP request libraries and the configuration options available to you in it. We were having an issue with occasionally hanging connections recently and it's possible that it may be related -- but if that's the case, you shouldn't have it occur to you every time -- it would be one out of X times. I'm curious where the connection is hanging -- while you are sending HTTP request headers or when your HTTP client is awaiting a response?
