### Overview

Create or update a Cloud Cost Management tag key description. The new description and optional cloud scoping are supplied in the request body. Omit `cloud` to set a cross-cloud default for the tag key. This endpoint requires the `cloud_cost_management_write` permission.

OAuth apps require the `cloud_cost_management_write` authorization [scope](https://docs.datadoghq.com/api/latest/scopes.md#cloud-cost-management) to access this endpoint.
