I’ve this problem that many others have been through. I’m doing everything correct but still i get this annoying “Failed to validate oauth signature and token” error 
Well, something got to be wrong I guess…
I’m trying to obtain a request_token by making a post to “https://api.twitter.com/oauth/request_token” with headers:
Authorization:
OAuth oauth_consumer_key=“MYVq…ywj2g”,
oauth_nonce=“m8NG0s4oc87AOIpuILafAeI1YoMv5Mu9”,
oauth_signature=“Bxb%252FFIfOG9KLVj%252FUNdV%252FycVlGPs%253D”,
oauth_signature_method=“HMAC-SHA1”,
oauth_timestamp=“1378976842”,
oauth_version=“1.0”
But it complains about signature and token.
Is my signature invalid somehow?
And for this request I dont need a token right??
