Hi Prabath, 1. Can't we use the implicit grant type instead of *Authorization code . *
- *Authorization Code* for apps running on a web server<http://aaronparecki.com/articles/2012/07/29/1/oauth2-simplified#web-server-apps> - *Implicit* for browser-based<http://aaronparecki.com/articles/2012/07/29/1/oauth2-simplified#browser-based-apps> or mobile apps<http://aaronparecki.com/articles/2012/07/29/1/oauth2-simplified#mobile-apps> Any reason why it can't be used. Is that because we use a proxy app and client app ? 2. Also can't we eliminate the use of web view. Rather use direct calls ? 3. Also can we have a custom grant type for mobile application , so that same level of security is achieved ?
