# deleteTenant

> Permanently deletes a tenant, unlinking it from all customers and removing its fields.
Threads that were associated with the tenant retain a tombstone reference but are no longer routed through it.
The tenant can be identified by either its Plain `tenantId` or its `externalId`.
Requires the `tenant:delete` permission.
