# Modify file information

`POST /nd/api/file/update_file`

## POST body parameters

| Parameter | Type | Description |
| --- | --- | --- |
| `file_id` | `string` | Required file ID |
| `name` | `string` | Optional new name |
| `description` | `string` | Optional description |

## Response

Fields listed in the source: `code`, `success`.



## Calling the Endpoint

Use `Authorization: Bearer <access_token>`. GET parameters belong in the URL query; normal business POST requests use JSON. Check HTTP status and then the business result. Confirm array serialization and ambiguous types with the deployment instead of inventing fields.
