How to find your Issuer ID in App Store Connect
Short version: App Store Connect → Users and Access → Integrations → App Store Connect API. The Issuer ID sits at the top of that page with a copy button — one UUID for your whole team, shared by every API key, and it never changes. Everything below is the map for when that path doesn't behave.
The exact click-path
- 1. Sign in at appstoreconnect.apple.com.
- 2. Open Users and Access from the home screen.
- 3. Switch to the Integrations tab along the top.
- 4. In the sidebar, pick App Store Connect API (under "Keys").
- 5. The Issuer ID is right at the top, above the key list — hit Copy. Done.
It's a UUID that looks like 57246542-96fe-1a63-e053-0824d011072a. If yours looks like that, you have the right string. If it looks like a 10-character code, you've copied a Key ID — different thing, keep reading.
What the Issuer ID actually is
Every request to the App Store Connect API is authenticated with a signed token (JWT), and that token has to say who's asking. The Issuer ID is the "who": it identifies your team as the token's issuer. That's why it's identical for every key your team creates and why it never rotates — keys come and go, the team stays. It's an identifier, not a secret, but the polite habit is to treat the trio (Issuer ID, Key ID, .p8 file) as one credential bundle and keep it out of screenshots.
Issuer ID vs Key ID vs Vendor Number
Three IDs, three jobs, endlessly confused with each other:
- Issuer ID — your team. UUID format. Same for all keys, lives at the top of the API page.
- Key ID — one specific key. Short code like 2X9R4HXF34, shown next to each key in the list.
- Vendor Number — your sales-reporting identity. Numeric, found in Payments and Financial Reports, needed for download and revenue reports.
Most tools ask for all three plus the .p8 file. The full key-generation walkthrough — roles, the one-time .p8 download, where each ID lives — is in our App Store Connect API key setup guide.
Issuer ID not showing? Check these
- Your role. The Integrations tab is visible only to Admin and the Account Holder. Developer or Marketing roles see nothing there — ask an admin to fetch the ID or bump your role.
- Team keys never enabled. The first visit to the page has a one-time "Request Access" button an Account Holder must click before any keys (or the Issuer ID) exist.
- Unaccepted agreements. A pending Apple Developer Program license agreement blocks chunks of App Store Connect, this page included. The Account Holder accepts it; things reappear.
- Individual keys. Personal API keys (scoped to your user, not the team) don't use an Issuer ID at all — if a tool asks for one, it wants a team key.
Where you'll paste it
Fastlane's app_store_connect_api_key, CI pipelines, RevenueCat, analytics tools — and FunnelHound, where the Issuer ID + Key ID + .p8 combo is the 60-second setup that pulls your funnel out of App Store Connect and onto your iPhone. The key lives on your device, talks only to Apple, and the dashboard-archaeology part of your morning retires.

Paste your Issuer ID into FunnelHound and get impressions, tap-through, installs and deletions on your iPhone — straight from Apple's API, no middleman server.
Get FunnelHoundData notes: click-path and role requirements verified against App Store Connect as of 2026. Apple reshuffles this UI periodically — if "Integrations" has moved again, the search box in Users and Access still finds it. The example UUID is Apple's own documentation sample, not a real team.
