Updated to your system seem to have broken Twitter Access Token API

oauth

So been running an app for the last year without a problem and just updated to support your new fixed callback endpoints, this is working we’re redirecting users to twitter they are authorising and Twitter is returning them to our application with an oauth_token & oauth_verifier, however, sending this verifier to oauth/access_token now results in your API Server responding with “Reverse auth credentials are invalid”.

So following on from this I have refreshed our consumer key and secret and updated that in the application and I’m still getting the same thing you seem to have broken your access token system which is a little strange as the access token system should not be the same as the redirection system the only point of contact should be the OAuth token and verifier database tables (this is coming from someone who as built and OAuth 2.0 system from the RFC’s).
