We use OAuth login in our application for a long time, but the links are sth. like: "http://twitter.com/oauth/request_token", and we just found the new one should be sth. like " http://api.twitter.com/oauth/request_token". It seems what we have now is OAuth 1.0A as mentioned in documents. We are not sure what should we change to avoid broken after June 30th. Any suggestions? Thank you.
