HTTP request

GET /groups/{group-id}/drive/items/{item-id}/versions/{version-id}/content
GET /me/drive/items/{item-id}/versions/{version-id}/content

Request headers

Name Description
Authorization Bearer {token}. Required. Learn more about authentication and authorization.

Response

Returns a 302 Found response redirecting to a preauthenticated download URL for the bytes of the file.

To download the contents of the file your application needs to follow the Location header in the response. Many HTTP client libraries will automatically follow the 302 redirection and start downloading the file immediately.

Preauthenticated download URLs are only valid for a short period of time (a few minutes) and don't require an Authorization header to download.

Example

This example retrieves a version of a file in the current user's drive.

Request

GET /me/drive/items/{item-id}/versions/{version-id}/content

Response

The call returns a redirect to where the contents of the version can be downloaded.

HTTP/1.1 302 Found
Location: https://onedrive.com/34FF49D6...

Remarks

OneDrive doesn't preserve the complete metadata for previous versions of a file.

When your app retrieves the list of available versions for a file, a driveItemVersion resource is returned that provides the available information about the specific version.
