重命名Facebook应用程序的托管URL

Question

I just started developing a Facebook App. I'm having trouble understanding some things working with Heroku, the free hosting platform for the apps.

So I created the App on Facebook. And from Heroku, I renamed the App. And from Facebook under App on Facebook, I changed Canvas URL and Secure Canvas URL accordingly. But the Hosting URL still has the old URL which was given when I created the app. The only option given is to remove it. How can I edit this and give the new URL?

Guidance would be greatly appreciated as I'm really confused with this. Thank you.

Answer 1

Yes, I'm same problem like you.

The reason why removing Hosting URL is I don't want auto-generated url something like 'something-####.herokuapp.com'

When I removed this url, however, Facebook authentication doesn't work anymore. So my recipe is,

• Change app name whatever you want.
• Just remove it hostring url.

• Reconfigure heroku's config var using CLI.

  $heroku config:add FACEBOOK_APP_ID=yours FACEBOOK_SECRET=yours

You can figure it out heroku config -s current variables. Check Readme.md in your Facebook/Heroku sample app folder for more detail.

Answer 2

I actually had a similar issue when I decided to change the app name on heroku. After a little bit of research I realized that if toy only change the items it allows you to change, facebook will still direct to your heroku app page.
