# Delete files

Delete temporary files, which cannot be recovered after deletion.

```text
POST $CLOUDSIGMA_API_BASE/connectors/file/delete
```

## Before you call this API

Configure the [regional API endpoint and authentication](https://omnifabric.cloudsigma.com/docs/developer/endpoints-and-authentication.html.md), and select the target workspace.

Make sure the file is no longer needed before deleting it.

Set the operation-specific values used in the request:

- `$CONN_FILE_ID`: Temporary file ID to delete, passed via `conn_file_id`.

## Request example

```bash
curl -X POST "$CLOUDSIGMA_API_BASE/connectors/file/delete" \
  -H "X-API-Key: $CLOUDSIGMA_API_KEY" \
  -H "X-Workspace-ID: $WORKSPACE_ID" \
  -H 'Content-Type: application/json' \
  -d "{
    \"conn_file_id\": \"$CONN_FILE_ID\"
  }"
```

## Request body

| Field | Type | Is it required | Description |
| --- | --- | --- | --- |

## Successful response

## Follow-up operations

When you need to confirm the deletion result, keep `conn_file_id` and [Preview file](https://omnifabric.cloudsigma.com/docs/reference/api/ai-studio/data-connections/connector-files/preview-file.html.md) or [Download file](https://omnifabric.cloudsigma.com/docs/reference/api/ai-studio/data-connections/connector-files/download-file.html.md) again. Both interfaces return a non-exist error when the temporary file has been deleted.
