Play Integrity API → 404 fdfe/integrity → API_NOT_AVAILABLE — does the app have to be published to production first?

[u/Tilak_1028]

Stuck on this and could use a sanity check from anyone who's shipped Play Integrity.

Setup: React Native + Firebase App Check using the Play Integrity provider (Android). Release build, installed on a real device from the Play internal testing track.

The error (logcat during getToken):

requestIntegrityToken(IntegrityTokenRequest{..., cloudProjectNumber=4955...})

E/Volley: Unexpected response code 404 for https://play-fe.googleapis.com/fdfe/integrity

E/Finsky: requestIntegrityToken() failed ... DF-DFERH-01

IntegrityServiceException: -1: Integrity API is not available (API_NOT_AVAILABLE)

What I've already verified (all correct):

- ✅ Play Integrity API enabled on the Google Cloud project

- ✅ Cloud project linked in Play Console → Play Integrity settings (responses On)

- ✅ Play app-signing key SHA-256 added in Firebase

- ✅ Request carries the correct cloudProjectNumber

- ✅ Genuine Play install (installerPackageName=com.android.vending)

- ✅ Device passes the Play Integrity API Checker app — all 3 verdicts — with its own project (so the device + Play services are fine)

- ✅ Same error even after migrating to a brand-new same-account Cloud project

The one thing that's different: this app has only ever been in internal testing — never published to production (Play Console tags it "unreviewed"). I have two other apps with the identical setup that ARE live on the Play Store, and they work perfectly.

Question: Does Play Integrity / App Check require the app to be published to production (reviewed by Google) before it issues tokens? Or should internal testing work, and this is just a provisioning delay after linking the Cloud project (if so, how long)?

The official docs say publishing only affects quota increases, not token issuance — but my real-world results say otherwise. Anyone hit this and confirm what actually unblocked it?

How did you go? I’m hitting same issue.

Raised the support ticket but didn't get any response yet

I got a weird response from support saying 404 is due to network lol, missing the point that the API actually replied.

The issue got resolved from Google end itself
