Facebook Business Manager Rate Limits

The Business Manager API surface (Marketing, Pages, Conversions, Catalog, Insights, Messenger, WhatsApp Business) is bound by Meta's Graph API rate-limiting framework. Limits are formula-based (Platform + Business Use Case + Pages/Messenger/Instagram windows) and depend on the app's App Review tier (Development, Standard, Advanced).
