# check_apple_ads_app_eligibility

Ask Apple whether an app may be advertised at all, PER PLACEMENT AND PER COUNTRY — the check Apple tells you to run before building a campaign around an app. Each row is ELIGIBLE or INELIGIBLE for one combination of placement, country or region and device class, with the minimum age rating for that market. A campaign targeting a country the app is INELIGIBLE in simply will not deliver there and nothing in the campaign build says so, so this is how you find out for free beforehand. adamId is REQUIRED. NO ROWS IS NOT THE SAME AS INELIGIBLE — it usually means the app is not owned by this organization; report that distinction rather than presenting it as a refusal. Read-only, free.

## Why check_apple_ads_app_eligibility is rated Low
