Find your App Apple ID
Locate the numeric Apple ID that identifies your app in App Store Connect.
Your App Apple ID is the numeric identifier Apple automatically generates for your app
(commonly around 10 digits, for example 1234567890). It is different from your Bundle ID and
from your personal Apple Account login, and is used by Voidhash to reference your app in
Apple's APIs.
Open App Store Connect
Go to App Store Connect, open Apps, and select your app.
Open App Information
In the sidebar choose General → App Information. On this page the read-only Apple ID is listed among your app's properties, alongside your Bundle ID.
Which Apple ID?
Here Apple ID means your app's numeric identifier — not your personal Apple Account login. Apple auto-generates it, and you can't edit it.
Copy the number
Copy the digits exactly (no spaces) and paste them into the App Apple ID field in Voidhash.
Shortcut
If your app is already live, the App Apple ID also appears in its App Store URL:
https://apps.apple.com/app/id1234567890 — the number after id is your App Apple ID.
