Ruby on Rails Authenticate Api using Devise


Devise is authentication solution for Rails. Before going any further i would like to add quick note on API. So API does not handle sessions (is stateless) which means one that provide response after you request, and then requires no further attention, which means no previous or future state is required for the system to work hence whenever we requesting to the server need to pass authentication details with all API and should tell Devise not to store authentication details.
