I am trying to add twitter credential to my login system, I keep getting 403 Client Error, I read this but doesn't have an answer. I followed the steps mentioned here no luck. I tried these patterns with Callback URL no luck:
http://127.0.0.1/complete/twitter/
http://127.0.0.1/oauth/complete/twitter/
website URL doesn't accept localhost so I put my old website which is not working at the moment. Please help, what's wrong with setting up twitter credential api?
