Nevermind, sooner after posting this i found -> "Twitter requires that all OAuth requests be signed using the HMAC-SHA1 algorithm"
But i can't get it to work with hmac either :/ CONSUMERKEY = 'dHbWZ6idD9VEuQ5tNUufA'; CONSUMERSECRET = '5ZzUafGDoFcAqOEubv3TAa01xb0Z326NMK6fLLrmk0'; basestring: POST&http%3A%2F%2Fapi.twitter.com%2Foauth%2Frequest %5Ftoken&oauth_consumer_key=dHbWZ6idD9VEuQ5tNUufA%26oauth_nonce %3D248256711275449040%26oauth_signature_method%3DHMAC- SHA1%26oauth_timestamp%3D1275449040%26oauth_version%3D1.0 authorization tag: Authorization: OAuth oauth_consumer_key="dHbWZ6idD9VEuQ5tNUufA", oauth_nonce="248256711275449040", oauth_signature_method="HMAC-SHA1", oauth_timestamp="1275449040", oauth_version="1.0", oauth_signature="SaG5KExe2frRkFMvZjJqHoZEp%2Bk%3D" Someone can spot the problem? Thanks in advance Arthur.
