Require data.is_valid=true and data.app_id to equal the configured app ID. Treat data.type as the token-type check and compare it with the integration's expected type (USER, PAGE, SYSTEM_USER, or APP); do not infer type from lifetime. Use data.scopes as the app-level permission set and inspect data.granular_scopes for target restrictions: each entry names a scope and may list target_ids; require the needed scope and, when target-scoped, the expected Page/ad-account/WABA/other asset ID. If target_ids is absent, Meta's debug_token documentation says the permission applies to all targets. For a user access token, additionally call /{user-id}/permissions and require the required permission's status to be granted; declined and expired are not usable, and login approval is not proof because a user can grant only a subset. For Page and System User tokens, use the PAGE/SYSTEM_USER type plus granular target IDs and the relevant asset/task or least-privilege endpoint check; current Meta docs describe Page tokens as page-specific and System User tokens as automated Business-asset credentials. Record app_id, type, is_valid, expires_at, data_access_expires_at, scopes, granular_scopes, and the checked asset ID, then compare them with the exact endpoint's current requirements.
