# View data privilege operation

```{raw} html
<div class="mo-api-page-show-toc" aria-hidden="true"></div>
```

View the processing progress and per-resource results for a data-privilege change. A successful request only reads the current state; it does not mean the grant is complete.

```text
GET https://moi.matrixorigin.cn/newmoi/workspaces/{workspace_id}/iam/roles/{role_id}/data-privilege-operations/{request_id}
```

## Preparation before calling

First [select a role](../roles/list-roles.md#select-a-role). Then keep the change identifier returned by [applying data privileges](apply-data-privileges.md#continue-tracking-the-change) or by a repair operation.

Prepare a [personal access token](../../../../../guides/genesis/api-keys.md) with the required permissions for the target workspace and the [target workspace ID](../../../../../guides/ai-studio/resource-center/workspace.md#copy-a-workspace-id).

### Select the change to track

Use the identifier returned by [applying data privileges](apply-data-privileges.md#continue-tracking-the-change) or a repair operation to view the current result of that same grant change.

## Successful response

Returns the operation state and per-resource results for the original request. Keep viewing when the state is `applying`; the operation is complete at `succeeded`. For `failed`, `drifted`, or `unknown`, review the resource results and decide whether to repair it.

## Next steps

### Determine whether repair is applicable

Only [repair a data privilege operation](repair-data-privilege-operation.md) when its result shows that repair is needed or cannot be confirmed. Continue viewing while processing has not ended; a succeeded or clearly failed change is not eligible for repair.
