Facebook app - login through omniauth - OAuthException 191

Question

I am facing with the problem:

  "error": {
      "message": "Invalid redirect_uri: Given URL is not allowed by the Application configuration.",
      "type": "OAuthException",
      "code": 191
   }

I set up in my app the needed keys and tokens, in the Facebook's dev center I set up Site URL: to http://127.0.0.1:3001 and I am getting the error above. Also I tried to set up App Namespace: to http://127.0.0.1:3001, but I am getting error about bad address format... When I tried to fill out he App Domain: and set there my localhost, again the error for the bad format...

What is the correct configuration the fabebook app with localhost?

You need to use urls, what I would do add this to your hosts:

127.0.0.1 dev-machine
127.0.0.1 dev-machine.com

Then in the facebook settings use

dev-machine.com as your App Domain

dev-machine.com:3001 as your Site URL

Hi I'm new to rails, could you please tell me how do we add the above mentioned urls as hosts to the application?? – Aks.. Jan 07 '14 at 14:30

By hosts, I mean your hosts file on your local machine. This is usually in /etc/hosts. – Abe Petrillo Jan 07 '14 at 18:57
Thank you Abe Petrillo :) I'll do that – Aks.. Jan 08 '14 at 04:59

Yes in FB App you have to assign an IP Site/ App Domain.

Facebook matches this url with the url of the request where it came from.
You can not assign localhost or 127.0.0.1
You have to enter the IP address your server. Also if it is rails then call the site with your-ip:3000 instead of localhost:3000; I use 192.168.1.154:3000
Enter the same IP address in IP of the site and APP Domain in your FB APP Settings.
To get your IP run ifconfig command in terminal if it is Linux or ipconfig if windows.

let me know if it doesn't work.

This is a wrongly accepted answer. FB does let you use localhost. But the port (:3000) should be indeed specified in Site URL (ex. http://localhost:3000/). Otherwise (http://localhost/) just won't work. – valk May 31 '14 at 21:23
On the development machine I assigned 'http://127.0.0.1:5000/users/auth/facebook/callback' in **devise.rb** callback settings and it works. I have problems with the real host name in production **Heroku** hosting. – Fabrizio Bertoglio Mar 02 '17 at 08:45

in the facebook App Page -> the basic tab. find "Website with Facebook Login" Option.

you will find Site URL: input there put the full URL (i.e http:// localhost:3000 if you are in Development mode) [* note : not "App Domains"]

I encountered this error and it was incredibly frustrating. The solution? I wasn't actually passing parameters properly in the query string. When I manually built my URL and submitted it using the browser, everything worked fine. Crap.

So, essentially, if you're getting this error it may actually be a symptom of something totally unrelated to the redirect_uri -- it just happens to be the first error triggered when your parameters are messed up. I hope that saves you the hours I spent on this.
