Hello I have searched this group for this error for some time without success. My base-string is,
POST&https%3A%2F%2Fapi.twitter.com%2Foauth %2Frequest_token&oauth_callback%3Dhttp%253A%252F%252Flocalhost %253A3005%252Fthe_dance%252Fprocess_callback%253Fservice_provider_id %253D11%26oauth_consumer_key%3DBQdOVY4TyFCEtNxNVwwFJw%26oauth_nonce %3DQP70eNmVz8jvdPevU3oJD2AfF7R7odC2XJcn4XlZJqk%26oauth_signature_method %3DHMAC-SHA1%26oauth_timestamp%3D1299953987%26oauth_version%3D1.0 To now I have had no problem getting same oauth_signature as the official document, http://dev.twitter.com/pages/auth . I changed some of the base-string into my own, such as oauth_consumer_key and oauth_timestamp, and using my own consumer_secret, tried to get oauth_token without success. I think the oauth_callback value is not related with the error 401, which I didn't touched. Either with oauth_nounce. What should I check first? Where can I find more kind example? I am using Asp.net + Javascript for this authentication. Any input is appreciated. -- Twitter developer documentation and resources: http://dev.twitter.com/doc API updates via Twitter: http://twitter.com/twitterapi Issues/Enhancements Tracker: http://code.google.com/p/twitter-api/issues/list Change your membership to this group: http://groups.google.com/group/twitter-development-talk
