Working on a mobile app, have a button that triggers the facebook log-in prompt and have created a holder on the facebook devs site and input the correct key etc, however i've left "domain" blank, since this is never going to be a facebook game, I just want permissions to post from it to a wall etc.
However, whenever I try and log in via the game on desktop it throws an error saying "Given URL is not permitted by the application configuration.: One or more of the given URLs is not allowed by the App's settings. It must match the Website URL or Canvas URL, or the domain must be a subdomain of one of the App's domains."
and on mobile the button does nothing at all (despite correct key being fed to CocoonJS)
So presumably I need to specify a domain on the facebook dev site...
Being an android game and not a facebook game, what on earth do I feed it for a domain?
