What is App Store Connect?
App Store Connect is Apple's web portal for managing apps on the App Store. Developers use it to create an app record, upload builds, run TestFlight, fill in the store listing and privacy details, set prices, submit for App Review and follow sales. Access comes with a membership in the Apple Developer Program.
More about App Store Connect
It also has an API, so tools can do the same work with a key instead of clicks. Every app on the App Store belongs to the App Store Connect account that published it, and that account is paid what the app earns.
