2. Drive Installs and Re-engagement to your game
with Requests and User Notifications
Requests and User to User Notifications are two of the main drivers of organic traffic
on Facebook developers can control.
Requests and User Notifications are sent by a player to a specific list of friends, and always carry a call-to-action that the sender
would like the recipient to complete. We’ll cover all the best practices that will help your game to leverage these channels the
most:
• Send Experience: Multi-friend selector, frictionless requests, referral system…
• Placement and Context: prominent invite button, optimal in-game placements…
• Conversion: Targeting options, structured requests…
• Match Maker: with a few/no Facebook friends playing the game

3. Best Practices from the Facebook Policy Team
Inviting Friends: https://developers.facebook.com/docs/games/invitable-friends/v2.2
• Apps should allow people to select more than one friend to invite in the Request Dialog.
• Apps should not pre-select friends for people to invite. People prefer to choose exactly whom to invite.
• Allow users to select whom to send requests.
Permissions:
• Make sure people have granted your app the user_friends permission. Apps will not receive results from the
invitable_friends API without this permission.
Multi-Friend Selector: https://developers.facebook.com/docs/games/multi-friend-selector/v2.2
• If your app has a multi-friend selector, you should ensure that users can search for friends.
• Additionally, you should only display the selector if you have confirmed that you can display back at least
one friend.

4. Common Mistakes & Misconceptions
Referral-Based Rewards:
• Apps should not reward people for sending invitations. However, apps can reward people for sending invitations if their
friends end up authorizing the app.
Invitable_Friends:
• The invitable_friends API is only available for games with a Canvas integration using version 2.0 of the Graph API. Apps
without a functioning Canvas integration will not have access to this API.
• https://developers.facebook.com/docs/games/invitable-friends/v2.2
Requests:
• People will only see request notifications for games on the platforms where those games exist. For example, if a game only
exists on iOS, a request notification will not appear on desktop.
• https://developers.facebook.com/docs/games/requests/v2.2#overview
• When people accept requests, they are not automatically deleted. It is the developer's responsibility to ensure that
requests are deleted once consumed.
