## Supported methods and overview&#x20;

* `GET` - downloads the data associated with a specific file object/[Secure Object](/3.4/api/working-with-files-and-folders-fundamentals.md#secure-object) version (specified by `versionId`) from storage via the Covata Platform's Content Service.

This data can be downloaded in either unencrypted or encrypted form.

> [!NOTE]

> * Whenever data is downloaded from the Content Service in unencrypted form, it is decrypted (after being retrieved from storage) through a separate Content Service process.

## Supported roles and conditions&#x20;

This API endpoint supports requests utilizing Covata user accounts with the following [roles](/3.4/admin-org/administering-users-within-an-organisation.md#an-organisation-users-roles) (as described in the [Organization Administrator's Guide](/3.4/admin-org.md)) and conditions:

* [Originator](/3.4/admin-org/administering-users-within-an-organisation.md#originator-role) - when this user owns the file object associated with the version whose ID is specified by `{versionId}` in the request's URL.
* **Originator**, [Collaborator](/3.4/admin-org/administering-users-within-an-organisation.md#collaborator-role) and [Ad hoc](/3.4/admin-org/administering-users-within-an-organisation.md#adhoc-role) - when this user is a collaborator with the **Rename** [permission](/3.4/api/access-service-api-v1-permissions-sets.md) on the file object associated with the version whose ID is specified by `{versionId}` in the URL. (The **Rename** permission restricts access to collaborators who have been applied either the **Modify** or **Manage** *permission set* on this file object.)

The Covata Platform's resources available to a Covata user meeting the criteria above is determined by the access token submitted in the [header](/3.4/api/content-service-api-v1-versions-versionid-contents.md#content-service-api-v1-versions-versionid-contents-required-headers) of requests to this endpoint.

## Required headers&#x20;

The appropriate access token as the `Bearer` token:

* `Authorization: Bearer eyJhbGciOiJSUzI1NiJ9.eyJleHAiOjE0NjcwMTY2NjYsInVzZXJfbmFtZSI6ImFsZXgub...`

## Required parameters&#x20;

The following optional parameter can be sent in the **URL** of the request:

* **format** - Specify either the value `plaintext` if downloading the file version's data in its decrypted form or `encrypted` if downloading the file version's encrypted data 'as is'; e.g. decryption will be conducted locally by the client application. \

  **Example:**

  ```text theme={null}
  https://content-service.xy-company.com/api/v1/versions/987654321098765432/contents?format=encrypted
  ```

## Optional parameters&#x20;

The following optional parameter can be sent in the **URL** of the request:

* **encoding** - Specify the value `base64` to download the file version's data as [Base64](https://tools.ietf.org/html/rfc4648)-encoded data. Otherwise, omit this parameter to download the file version's data as raw/binary data. In both cases, the `Content-Type` in the response is `application/octet-stream`.

  **Example:**

  ```text theme={null}
  https://content-service.xy-company.com/api/v1/versions/987654321098765432/contents?format=encrypted&encoding=base64
  ```
