###Application secret To get the application secret you have to be in admin role of JVM Bloggers on Facebook.

• the second one to change the code to access user token: GET https://graph.facebook.com/oauth/access_token?client_id={app-id}&redirect_uri={redirect-uri}&client_secret={app-secret}&code={code}

{app-id} can be found on the application dashboard.

{redirect-uri} can be anything based on App Domain defined on the application settings page.
