I have a React/Horizon app with facebook login.
I am wondering if there is any option to work with facebook login from localhost?
There are some other good answers here. However I want to add information about how to create a Test app (as recommended by Facebook).
Go to the page to manage Facebook apps (you, the admin must be logged in): https://developers.facebook.com/apps/
Hover over the block containing your live Facebook app and click on the three dots button that appears on the bottom right corner. Then select Create Test App from the menu.
The test app will be created with a snapshot of your production app's settings. After this, you can independently edit the settings of your test app without affecting your production app.
See the documentation here: https://developers.facebook.com/docs/apps/test-apps/
Regarding the rest of the setup:
keep your app in Development mode
go to Settings -> Basic (left hand menu) and
enter "localhost" for the App Domain
change your Site URL to the localhost version (e.g. http://localhost:3000/users/auth/facebook)
Here are some (Jan 2022) screenshots of my test app settings, which I just use for Facebook login.
Settings -> Basic
Settings -> Advanced
Facebook Login -> Settings
You need to register as facebook developer and create you app there. Once you have your web app registered you can go to your app and click on add product.
Add Facebook Login. Then enable Web OAuth Login and add your localhost in the textfield below and save, you should be able to access it. Attaching a sample screenshot of my facebook app.
Disclaimer: This answer was written in 2019 and I have not been able to keep up with the latest changes introduced by Facebook, this is here for reference purposes.
So in my case doing the following things worked for me.
Make sure your application is in development mode
Make sure you don't have anything in Valid OAuth Redirect URIs when working from localhost
Make sure you don't have anything in App Domains also
Make sure you have entered localhost in your site url
I would like to add an update: July 2019
Facebook now allow localhost automatically in development mode and it is blocked in production mode. All you have to do is turn on development mode in your app settings and you are good to go.
You do not need to add localhost as a redirect URL anymore.
Here you can see the error at the Redirect URLs when I'm trying to add localhost.
You can use a tunneling tool like https://ngrok.com/ which is free for at least one instance. Then you can create a test App as already suggested and use the ngrok generated urls in this test app.
After test I see that we don't need to setup anything in facebook app
(even Site URL don't need to be localhost)
Just need to use https://localhost instead of http://localhost. Then login work and we able to receive response.
Note: If you see SSL warning after you enter https://localhost to browser. Just click on Advance -> Process to ... (unsafe)
The method FB.login can no longer be called from http pages.localhost, I get: App domains must match the domain of the Facebook Web Games URL (https), Mobile Site URL, Unity Binary URL, Site URL or Secure Page Tab URL. Please correct at least one of these domains: localhost
Using something like local-ssl-proxy is an easy way to solve this.
So I also have problem with working with Facebook Login from localhost in React and Express and I got this info:
"The method FB.login can no longer be called from http pages". After click login button, app just crashed.
My solution to fix this mess, was delete Facebook cookie from this localhost page. After this, I still have this error about http, but I can proceed and test login options.
Other solution is working in incognito mode.
I'm using Firebase to log into Facebook and honestly, the easiest thing was to just get your localhost served over HTTPS. I used ssl-serve for it, since I was working on a very basic ESM app with no build tools. But most build pipelines (e.g. Vue's vue-cli, React, etc.) have a CLI option for SSL as well.
What I used:
cd src && npx ssl-serve --ssl --clipless --port 5000 --silent
Then you just accept the self-signed cert ("Advanced" > "Continue" in Chrome/Brave) and you won't need to mess around with swapping the redirect URIs or domains under your Facebook app's config, nor the Facebook App IDs on Firebase.
Facebook provide Test App for your current app to get access to localhost environment. Create a test app on facebook https://developers.facebook.com/docs/development/build-and-test/test-apps/
and use the API and Secret to get testing on localhost.
I would like to share my experience for anyone who use firebase authentication combine with facebook login. Below solution work for me:
First, set your App Mode is development at https://developers.facebook.com.
Next, when you enable facebook login in Firebase Authentication, firebase will give you a link call OAuth redirect URI, you will have to add this link to the Valid OAuth Redirect URIs field in the setting page of your facebook app (inside tab Facebook Login). This is the most important step.
Finally, you don't need to do anything else. Good luck.
If you're using react and your local server is on http and still getting the error run this in the terminal to start up an https localhost
Windows:
set HTTPS=true&&npm start
Windows Powershel:
($env:HTTPS = "true") -and (npm start)
Linux and macOS (Bash):
HTTPS=true npm start
when it opens in the browser
click Advanced and proceed
a little background:
I have an hotspot page wich integrate with facebook login oatuh. The app runs on facebook api v.2.4 and uses node/express/passport to handle the login process
The only option i pass to the oauth fb page is display: touch, so the login page works fine without cookie support
the issue:
since a few days , only on osx 10.11/cna the login can't be processed because of no cookie support in CNA (this should mean that fb ignores the display option, in this case only)
the same request made from a ios device from within the cna works fine
I've already confirmed the display option is actually send, so my best guess is that fb started overwriting/ignoring this option. Also I can't find any reference in the fb api docs anymore (except for display=popup in the manual login page)
Any hint about this ?
thanks

Not sure if you still have this issue, but I can confirm facebook login definitely works end to end inside the CNA on 10.11. The CNA does allow cookies, what it doesn't allow is access to existing cookies in safari or access to localStorage and sessionStorage.
If you have your FB sdk configured with cookies=false, this may well be your issue. When set to false I believe the sdk is then attempting to use local storage.
The other thing to check would be what you have in the walled garden list. We have just got to the bottom of this issue after a lot of frustration. Allowing certain CDN networks actually causes iOS to complete it's internet check and no longer think it's behind a captive portal. I added an answer here https://stackoverflow.com/a/41273984/4427589.
As I said, I can confirm it definitely works end to end inside the popup.

Does anyone know if there is an (undocumented?) field/property in graph api I can use to disable sandbox mode for an app?
I have checked https://developers.facebook.com/docs/reference/api/application/ and googled my eyeballs sore, but can't find anything, is this only available from the app settings panel on developers.facebook.com/apps?
No, there is no undocumented/documented property for this. You must enable/disable manually from your app settings.
I have created a tab-application for a client's Facebook Page and put it in sandbox mode.
The client has a "tester" role for the app.
However, when we're trying to view the app with her Facebook User, the content appears blank like this:
But I can view the app just fine. And the client used to be able to see it until last week.
What can the problem be? It's such a shame, since they're supposed to set it up using a built-in admin-interface.
Thanks in advance!
Kind regards,
Tobias
This could be an SSL issue. If you don't have a signed SSL certificate yet, make sure your client has disabled secure browsing in their Facebook Account Settings > Security.
I've created a facebook app for my site and an html page where i can login into the user account allowing the app for do that...
So, this work correctly when i attempt to logon with the my account, that are the ADMIN of the page, but with other else account, the facebook popup window retrieve an error (with no useful details).. my sensation is that the app is not open to the public, how i can open it for the public?
Are you sure you haven't forgotten to take the app out of Sandbox mode in the app's advanced settings?
By default sandbox mode is not enabled, but yes try this way. If it's not that can you please bring us some code?
