# Copy files

`POST /nd/api/file/copy`

## POST body parameters

| Parameter | Type | Description |
| --- | --- | --- |
| `file_ids` | `ID collection` | Required source file IDs |
| `target_id` | `string` | Required destination folder ID |

## Response

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

The source describes file_ids as both an array and string; confirm serialization with the deployment. Use the returned copyKey with copy_progress to check completion; acceptance is not completion.

## 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.
