iTunes Connect is a web app for developers to submit and manage their apps for sale on the App Store, distribute builds to testers using TestFlight Beta Testing, complete legal and tax documents, and view sales, usage, and earnings information.
Initially, only the team agent (the person who joins the Apple Developer Program) has access to iTunes Connect and is assigned the Legal role. Later, the team agent can create additional users in iTunes Connect and assign specific roles to users, such as Developer, Finance, or Legal.
For more information on iTunes Connect, read iTunes Connect Developer Guide. To understand what each role can do, go to Program Roles and iTunes Connect Roles.
Sign in to developer.apple.com/account, and click iTunes Connect.
Click Go to iTunes Connect.
Tip: To go directly to iTunes Connect the next time, select "Take me straight to iTunes Connect…” and then click Go to iTunes Connect.
The iTunes Connect homepage appears showing the sections that contain tasks you can perform depending on your role. For example, click My Apps to view all your app records and versions.
