How can I ask users to come and do something in my app?
It’s easiest to think of requests as Notifications with an action. They carry a little more weight than general invitations into an application because they have a specific call to action associated with them, as shown in Figure 2-34.

The general idea is that you’re requesting users to take an action in your app based on an action that another user has already taken. Requests tend to have a higher click-through rate than Notifications because they contain an obvious call to action, so carefully consider how you can leverage them.
