We are pulling data from the salesReports endpoint, specifically focusing on the Subscriber, Subscription_Event, and Subscription report types. Our goal is to perform internal analysis on our subscriptions, such as comparing renewals to new subscriptions.
However, we have observed that the data quality is not as high as we would expect from Apple. While some insights can be gleaned with a degree of uncertainty, our biggest concern is the discrepancy between the data obtained from the API or manually downloaded from the portal (https://appstoreconnect.apple.com/trends/reports) and the data displayed in the Portal visualizations (https://appstoreconnect.apple.com/trends/events). This discrepancy makes cross-checking difficult and lowers our confidence in the data’s accuracy.
Is anyone else experiencing similar issues, or has anyone managed to obtain reliable data for their app(s)?
