When you create an app you will be asked how the app will be used:
The choice you make determines its type. There are five possible types: Consumer, Business, Instant Games, Gaming Services, Workplace, or None. Once you choose an app type, your app will only be presented with products, permissions, and features that are available to that app type.
The Consumer app type is for apps that integrate consumer-related products like Facebook Login to provide app users with a more personalized experience.
Consumer apps are subject to an additional layer of Graph API authorization called access levels.
Business apps are subject to an additional layer of Graph API authorization called access levels.
Business apps do not have app modes and instead rely exclusively on access levels to determine who can grant them permissions and who will be affected by features.
Learn more about app modes.
The Instant Games app type is for gaming apps that are played on the Facebook Platform.
The Workplace app type is for SaaS apps that can be installed by Workplace customers. Refer to our Workplace documentation for more information about Workplace and SaaS apps.
Apps designated as None are apps that don't fit any of our app types. Apps designated as None have access to all products, permissions, and features.
If you created your app before March 22, 2021, you may remove your app's type by going to App Dashboard > App Review > Permission and Features > Looking for additional permissions and features? and clicking the Remove App Type button. Any permissions or features already approved through App Review will retain their approval status. Note that if you remove your app type, you will be unable to restore it later; you must create a new app with the desired type instead.
Removing the app type will restore the app modes toggle and set the mode to what it had been at the time of type selection.
