Can't authorize to twitter. Writes: Failed to validate oauth signature and token... Nodejs. Checked timestamp - almost the same as twitter's.
Request body is empty. Everything seems to be done correctly...
Moreover when i try cURL command, provided by OAuth tool in Home → My applications it returns the same answer!
Could use some more details to understand your issues. There are so many reasons you can get that error. Make sure that you're not using cookies of any kind, that you're connecting over HTTPS, and you've tried everything in Troubleshooting OAuth 1.0A.
