## DELETE /api/v2/shared-hosting/{accountId}/actions/upgrade

**Cancel scheduled hosting change**

Cancel the open next-period package change returned as `scheduledChange` by `GET /api/v2/shared-hosting/{accountId}/actions/upgrade`. The account remains on its current package. When the scheduled change had already replaced a renewal invoice, the current-package renewal is restored and returned as `renewalInvoice`. Cancellation is blocked after renewal payment has started or while the change is actively being applied.
