User Profile

Hello,we have an app, where users can track times calling an API from an other external service (other product). After tracking all times, the user can order a report via the external API. This order will be charged and after the payment, an email with the monthly report as pdf file will be sent from the external product to the customer.Now the question: Do we need to add IAP here for the purchase of the report and pay the 30% commission?Thanks and regards
