What are App Domains in Facebook Apps

Question

I want to add the ability to  login with Facebook  to my site  But I am confused when I register my site in Facebook Apps  What should I input into App Domains

User · Answer

I think it is the domain that you run your app    For example  your canvas URL is facebook yourdomain com  you should give App domain as  yourdomain com

To add to the answers above  the App Domain is required for security reasons  For example  your app has been sending the browser to  www example com PAGE NAME HERE   but suddenly a third party application  or something else  sends the user to  www supposedlymaliciouswebsite com PAGE HERE   then a 191 error is thrown saying that this wasn t part of the app domains you listed in your Facebook application settings

It s simply the domain that your  facebook  application  wich means application visible on facebook but hosted on the website www xyz com  will be hosted  So you can put App Domain   www xyz com

In this example    http   www example com 80 somepage parameter1  hello  amp parameter2  world   the bold part is the Domainname  80 is rarely included  I post it since many people may wonder if 3000 or some other port is part of the domain if their not staging their app for production yet  Normally you don t specify it since 80 is the default  but if you just want to specify localhost just do it without the port number  it works just as fine  The adress  though  should be http   localhost 3000  if you have it on that port
