* Verifies a Play Integrity API token server-side and returns whether the
|

|
* device meets basic integrity requirements.
|
||
|
|
*
|
||
|
|
* Called by [PlayIntegrityChecker] on app startup. Requires the caller to be
|
||
|
|
* authenticated — the Firebase Auth token is verified automatically by the
|
||
|
|
* Functions runtime.
|
||
|
|
*
|
||
|
|
* Setup required before this function works in production:
|
||
|
|
* 1. Enable the Play Integrity API in your Google Cloud project.
|
||
|
|
* 2. Link the Cloud project to your Play Console app (Play Console →
|
||
|
|
* Setup → API access → Link to Cloud project).
|
||
|
|
* 3. Grant the Cloud Functions service account the "Play Integrity API User"
|
||
|
|
* role in IAM, or use a dedicated service account key via
|
||
|
|
* GOOGLE_APPLICATION_CREDENTIALS.
|
||
|
|
*
|
||
|
|
* If the API is not yet configured the function fails-open (returns
|
||
|
|
* passed: true) and logs the error, so unconfigured environments don't
|
||
|
|
* block users. Firebase App Check remains the server-side gatekeeper.
