My oAuth appears correct as I can get request and access tokens via POST however everytime I issue a GET request I get a 401 unauthorized error. I have triple checked my authorization string. I am trying to use GET users/show for an authorized user that I have an access token, secret etc. I have tried deleting and recreating the Twitter app. I am running on my dev machine from localhost. Any ideas why I can’t issue GET requests?
