About

Admin API keys grant programmatic access to organization and compliance APIs. An attacker can delete legitimate admin API keys to break security monitoring or integrations, or to cover tracks after creating replacement credentials they control. Deletion without a nearby rotation event points more at sabotage than routine key hygiene.
