I need to check if the given Facebook app id is valid. Also, I need to check which domain and site configurations are set for this app id. It doesn’t matter if it’s done through PHP or Javascript.
I checked everywhere but couldn’t find any information about this. Any ideas?
You can validate the ID by going to
http://graph.facebook.com/<APP_ID>and seeing if it loads what you expect. For the app information, try using admin.getAppProperties, using properties from this list.
