`GET /people/documents/{id}/download`

Read-only: Reads and returns; changes nothing.

Retrieves a download link for a document. The response contains a short-lived link, not the file itself. Request a new link each time you start a download instead of saving the link.

## Parameters

| Name | In | Type | Required | Description |
| --- | --- | --- | --- | --- |
| `Api-Version` | header | string · v1 | yes | The API version this request targets, named by its public identifier. Required on every request; omitting it, or naming a version this company does not have, is answered with 400. This document describes version `v1`. |
| `id` | path | string | yes | The unique identifier of the document you want to download. |

## Response

`200` Success

Under `data` (downloadDocumentOutput):

| Field | Type | Required | Description |
| --- | --- | --- | --- |
| `id` | string | yes | The unique identifier for the document the link points at. |
| `fileName` | string | yes | The stored file name of the document. Save the downloaded bytes under it. |
| `mimeType` | string | no | The MIME type of the stored file. Absent when storage does not report one. |
| `fileSizeBytes` | number | no | The size of the stored file in bytes. Absent when storage does not report one. |
| `downloadUrl` | string | yes | A short-lived pre-signed URL the file's bytes are fetched from. It expires and is not a stable link. |
