Connecting ASCStats to App Store Connect
To show your stats, ASCStats needs four pieces of credentials from your Apple account. You generate them once in App Store Connect, paste them into ASCStats, and they're stored in your Mac's Keychain — nothing is sent to us.
.p8 file you download once.You'll need to sign in to appstoreconnect.apple.com with an account that has the Admin or Account Holder role — only those roles can generate API keys. Have it open in a browser tab and keep it side-by-side with ASCStats.
Create an App Store Connect API key
This one key gives you three of the four credentials: the Issuer ID, the Key ID, and the private key file.
In App Store Connect, go to Users and Access, then select the Integrations tab at the top. In the sidebar, under App Store Connect API, choose Team Keys.
At the top of that page you'll see Issuer ID with a long UUID next to it. Click to copy it.
Click the + (Generate API Key). Give it a name like ASCStats and assign an access role. Admin or Finance works well — the key needs permission to read sales and finance reports. Click Generate.
The new key now appears in the list. Its Key ID is the 10-character code in the Key ID column.
In the key's row, click Download API Key. This saves a file named AuthKey_KeyID.p8 — this is your private key.
.p8 file somewhere safe — if you lose it, you'll have to revoke the key and create a new one.Find your Vendor Number
The vendor number identifies your account in Apple's sales reports. It lives in a different section of App Store Connect.
From the App Store Connect home, open Payments and Financial Reports (you can also use Sales and Trends → Reports).
Your Vendor No. is shown in the top-left corner of the page, just below your team name. It's the same 8-digit number across all reports.
Enter it all into ASCStats
Open ASCStats' settings and fill in the four fields you just collected.
Once connected, ASCStats fetches your data straight from Apple and your menu bar comes to life. First sync can take a moment while Apple prepares the reports.
These credentials let ASCStats read your sales data — treat them like a password. ASCStats keeps them in the macOS Keychain and talks only to Apple; nothing is sent to reneph.de. If a key is ever exposed, you can revoke it anytime from the same Integrations page in App Store Connect and generate a fresh one.
