Hi. I have the same issue, but may i ask why you are performing a GET request with a POST signature? HTTP POST should be:
POST /oauth/request_token <Headers>\r\n \r\n callback=..&nonce=&... Not in the way you've shown us: HTTP POST: https://api.twitter.com/.../oauth_callback=..&;... Secondly, have you checked your timestamps so it matches the twitter server? Say you live in Sweden like i do, you need to compensate for the time difference with -1 so it matches GMT. Thirdly, are you URL encoding anything at all in the POST header? I think the signature needs to be URL encoded. This is what my Header and POST data looks like: http://groups.google.com/group/twitter-development-talk/browse_thread/thread/40b41730d2144ca9 On Thu, Jun 30, 2011 at 12:19 AM, miloshes <blask...@gmail.com> wrote: > Hi guys, > > I am new here, working on yet another twitter client for desktops. > It's Adobe AIR desktop app written in AS3.
