Getting "Sorry that page doesn't exist" when I try to start getting authorization from a user


I’m trying to figure out how to have a user authorize my Twitter application to send tweets on their behalf. The only discussion I’ve been able to find that discusses this is However this thread is referencing API v1.0 which is deprecated. I also found which mentions a flow of /oauth/access_token /oauth/authenticate /oauth/authorize /oauth/request_token. However if I try to access /oauth/access_token I get back a page that says that that page doesn’t exist. My exact URL that I’m using is Does anyone know why I’m getting this error and can someone tell me if the four REST calls I mentioned above are correct for getting a token for a user having authorized my application?
