Hi Andy, thanks for replying. Yes, I did sign the url as you mention.
As a test, I also sent a request to "https://api.twitter.com/1/account/verify_credentials.xml" >From this I get authorization ok using a standard call when using an "Authorization" header, but as soon as I use the header "X-Verify- Credentials-Authorization" then I get the 401 not authorized. I created the signed request using a GET not a POST, then modify the Realm part, as instructed by other posts. The credentials were creatd using the request url of "https://api.twitter.com/1/account/ verify_credentials.xml". As far as I can tell, I am doing everything correctly - but obviously not. Can't fathom what the problem is, I wish Twitter API provided more feedback for debugging.
