The Apple App ID is a two part string used to identify one or more apps. Specifically, the Apple app ID is your team ID and bundle ID joined with a period, for example: 1A234H7ABC.com.yourdomain.YourApp.
You or your mobile developer can find your team ID in the Apple’s Developer Portal under Organization Profile > Account Summary. When you enter the Member Center on http://developer.apple.com, click you name on the top right and click on “View Account”. You will find your team ID under the Developer Account Summary.
NOTE
- In order to support Universal Links, the Apple App ID will need to be included in your Bitly iOS app configuration. It is used to create an Apple site association file on the Custom Domain that support Universal Links.
