+## Permanent workspace delete
+
+The soft-delete method may not fit in some scenarios such as development and testing, where you need to repeat a deployment with the same settings and workspace name. You can permanently delete your workspace and “override” the soft-delete period. The permanent workspace delete operation releases the workplace name and you can create a new workspace using the same name.
+
+> [!Important]
+> Use cautious when permanently deleting your workspace since the operation is irreversible and your workspace and its data won’t be recoverable.
+
+The permanent workspace delete can be performed via REST API currently.
+
+> [Information]
+> Any API request must include a Bearer authorization token in the request header.
+>
+> You can acquire the token using:
+> - [App registrations](https://docs.microsoft.com/graph/auth/auth-concepts#access-tokens)
+> - Navigate to Azure portal in “developer tool” (F12), look in one of the “batch?” instances and look for the authentication string under “Request Headers” – it looks like this:  “authorization: Bearer <token>”. Copy and add it to your API call as shown in the examples.
+> - Navigate to Azure REST documentation site – press “Try it” on any API and copy the Bearer token and add it to your API call.
+To permanently delete your workspace, use the [Workspaces - Delete REST]( https://docs.microsoft.com/rest/api/loganalytics/workspaces/delete) API call with a force tag:
+
+```rst
+DELETE https://management.azure.com/subscriptions/<subscription-id>/resourcegroups/<resource-group-name>/providers/Microsoft.OperationalInsights/workspaces/<workspace-name>?api-version=2015-11-01-preview&**force=true**
+Authorization: Bearer eyJ0eXAiOiJKV1Qi….
+```

 ## Recover workspace
 
 If you have Contributor permissions to the subscription and resource group where the workspace was associated before the soft-delete operation, you can recover it during its soft-delete period including its data, configuration and connected agents. After the soft-delete period, the workspace is non-recoverable and assigned for permanent deletion. Names of deleted workspaces are preserved during the soft-delete period and can't be used when attempting to create a new workspace.
