App Store Connect (called iTunes Connect until 2018) is Apple's web console for everything that touches the App Store and TestFlight. Submissions, builds, in-app purchases, pricing, subscriptions, testers, reviews, sales reports, App Store Connect API keys, and team access all live here. It is a sibling to the Apple Developer portal, which is where certificates, identifiers, and provisioning profiles live.
