Invite Friends

Overview

The Invite Friends feature is available in LINE Versions (LINE MINI App and LINE Login LIFF). This feature is one of the most important tools for user acquisition and user activation, helping your Unifi Apps grow organically within the LINE ecosystem.

Referrals play a key role in driving viral spread among LINE users. We strongly recommend implementing this feature to maximize visibility and user engagement.
