I was using the Download Sales and Trends Reports API (GET https://api.appstoreconnect.apple.com/v1/salesReports), but at some point, the results started not displaying properly. (The reason for this is that all the +sales values aren't showing up in the CSV file.)
Below, I'll show you how to use the API in Python with a screenshot. (***** elements are hidden.)
If anyone knows why, please let me know.
