I am using this script in java https://github.com/fernandezpablo85/...eoExample.java to try retrieving informations about my profil in viadeo with its API. However I don't know what to write in the callback url (is it mandatory ?), since I don't have any site. If possible I am trying to do like with Linkedin where it redirects you to a site where you need to login so that you can get a code to pass to the java application.
Does someone has any idee in how to do so please ?
