App Store
Subscription offer code
A subscription offer code is an Apple mechanism for giving a referred user a discounted introductory price, used as the redeemer reward while keeping the reward attached to subscribing rather than installing.
In a referral, the sharer earns a commission and the referred user can get a reward. On the App Store, Attribloom delivers that reward as a subscription offer code returned when the app binds the affiliate.
The reward attaches to a paid action (subscribing), never to the install itself, which keeps it within Apple's rules. The app shows the discount only to referred users.
Frequently asked
Why not reward the user just for installing?
Apple's guidelines prohibit rewarding an install itself. The reward must attach to a post-install action such as subscribing, which is exactly how an offer code works.
