The updated commission rate will decrease to 2.5% on apps. Other iTunes content will still give affiliates a 7% commission.

"Starting on May 1st 2017, commissions for all app and in-app content will be reduced from 7% to 2.5% globally. All other content types (music, movies, books, and TV) will remain at the current 7% commission rate in all markets. We will also continue to pay affiliate commissions on Apple Music memberships so there are many ways to earn commissions with the program," Apple said in an email.
