Facebook Login allows you to control oAuth settings, and add a deauthorization callback URL and redirect URI validator.

Quickstart

The Facebook Login quickstart allows you to quickly get the code to implement Facebook Login into your app.

After you add a permission to your app, you can see the status for that permission:

Ready for live mode – This permission has been approved in App Review and you can publish your app
Ready for testing – You can test API calls to endpoints that require this permission and complete App Review permission testing requirements
Verification required – This permission requires a verified Meta Business Account added to the app

You can also see the number of successful API calls you have made to endpoints that require each permission.

Add more use cases

Click the Go back button in the upper right or Use cases in the left side menu to add more use cases to your app.

These are the use cases most commonly used with the use case you chose when you created this app.
