Hi All,

We are trying to integrate external system(.Net) to SFDC(server).  For this we are using oauth setup to establish connection between .Net to SFDC. In this setup we are using Call Back URL, https://localhost:8443/RestTest/oauth/_callback. 
In .Net code we are using consumer key, consumer secret, call back URL, while running .Net code we are not able to get access token from SFDC

Is there any issues with above Call Back URL.

Thanks Inadvance.
