get method

Gets a file's metadata or content by ID.

If you provide the URL parameter alt=media, then the response includes the file contents in the response body. Downloading content with alt=media only works if the file is stored in Drive. To download Google Docs, Sheets, and Slides use [files.export](/drive/api/reference/rest/v3/files/export) instead. For more information, see [Download & export files](/drive/api/guides/manage-downloads).

Request parameters:

fileId - The ID of the file.

acknowledgeAbuse - Whether the user is acknowledging the risk of downloading known malware or other abusive files. This is only applicable when alt=media.

includeLabels - A comma-separated list of IDs of labels to include in the labelInfo part of the response.

includePermissionsForView - Specifies which additional view's permissions to include in the response. Only 'published' is supported.

supportsAllDrives - Whether the requesting application supports both My Drives and shared drives.

supportsTeamDrives - Deprecated: Use supportsAllDrives instead.

$fields - Selector specifying which fields to include in a partial response.

downloadOptions - Options for downloading. A download can be either a Metadata (default) or Media download. Partial Media downloads are possible as well.

Completes with a

• File for Metadata downloads (see downloadOptions).

• commons.Media for Media downloads (see downloadOptions).

Completes with a commons.ApiRequestError if the API endpoint returned an error.

If the used http.Client completes with an error when making a REST call, this method will complete with the same error.
