notes: >-
  AdMob has NO sandbox for the REST management/reporting API.
  admob.googleapis.com has a single live environment, no test-vs-live key
  prefixes, no test mode and no simulated data — every call reads the caller's
  real AdMob account, and the v1beta write methods create real apps, ad units,
  ad unit mappings and mediation groups against production inventory. The
  sandbox surface AdMob does publish sits on the publisher-integration side: a
  permanent set of Google-owned demo ad unit IDs that always serve test ads, and
  a test-device mechanism for serving test ads against your own ad units. Every
  value below was read verbatim from Google's own test-ads pages on 2026-08-13;
  none is invented.
api_sandbox:
  available: false
  detail: >-
    No sandbox host, no test credentials, no test/live separation for the AdMob
    API. Treat every v1beta write as a production mutation.
  agent_warning: >-
    An agent given admob.report/admob.readonly on v1beta can create production
    inventory with no way to roll back and no idempotency key to make a retry
    safe. Gate every write behind human confirmation.
test_mode:
  mechanisms:
  - name: Demo ad units
    detail: >-
      Google-owned ad unit IDs that always return test ads and are safe to
      hard-code during development. Not associated with your AdMob account, so
      they carry no invalid-traffic risk. All share the publisher prefix
      ca-app-pub-3940256099942544.
  - name: Test devices
    detail: >-
      Register a device so your own ad units serve test ads — programmatically
      via RequestConfiguration.Builder.setTestDeviceIds() using the device id
      printed to logcat, or through the AdMob UI. Ads then render with a
      "Test Ad" label and clicks generate no reportable impressions.

    note: >-
      The iOS page publishes an equivalent demo ad unit table under the same
      ca-app-pub-3940256099942544 publisher prefix. Values not transcribed here;
      read them from the iOS page rather than assuming they match Android — they
      do not.
