Google Drive provides two options to gather information about
Drive users:
Using the about resource, you can retrieve
information about the user, the user's Drive settings, and
their system capabilities.
Using the apps resource, you can retrieve a
list of the user's installed apps, with information about each app's
supported MIME types, file extensions, and other details.
This guide explains how you can retrieve user info in Drive.
Get details about a user
To return information on a Drive user as an instance of
about, use the
get method. The returned values are measured
in bytes.
You must set the fieldssystem
parameter on
the get method to specify the fields to return in the response. In most
Drive methods this action is only required to return non-default
fields but it's mandatory for the about resource. If you omit the parameter,
the method returns an error. For more information, see Return specific fields.
The following code sample shows how to provide multiple fields as a query parameter in the request. The response returns the field values for the request.
Request
GET https://www.googleapis.com/drive/v3/about/?fields=kind,user,storageQuota
PERMISSION_ID: the user's ID within the Permission resources.
EMAIL_ADDRESS: the user's email address
List user apps
Google Drive apps are listed in the
Google Workspace Marketplace and
are used to make Drive more convenient such as the Google Docs
app or an add-on used within Docs to
sign documents. For more information, see Use Google Drive
apps.
To return a list of all the user's installed apps as an instance of apps, use the list method
without any parameters.
If you want to specify the fields to return in the response, you can set the
fieldssystem
parameter. If
you don't specify the fields parameter, the server returns a default set of
fields. For more information, see Return specific fields.
The following code sample shows how to return a list of all the user's installed apps in the request. The response returns the field values for the request.
To find a specific app, use one or more of the optional query parameters:
appFilterExtensions: Filter the search results using a comma-separated
list of file extensions. Apps within the app query scope that can open the
listed file extensions are included in the response. If appFilterMimeTypes
are also provided, a union of the two resulting app lists is returned.
Examples of extensions include docx for Microsoft Word and pptx for
Microsoft PowerPoint. For more examples of file extensions, see Export MIME
types for Google Workspace documents.
The following code sample shows how to provide multiple file extensions as a
query parameter: GET
https://www.googleapis.com/drive/v3/apps?appFilterExtensions=docx,pptx.
appFilterMimeTypes: Filter the search results using a comma-separated list
of MIME types. Apps within the app query scope that can open the listed MIME
types are included in the response. If appFilterExtensions are also
provided, a union of the two resulting app lists is returned. Examples of
MIME types include application/vnd.google-apps.form for Google Forms and
application/vnd.google-apps.site for Google Sites. For more examples of
MIME types, see Google Workspace and Google Drive supported MIME
types.
The following code sample shows how to provide multiple MIME types as a
query parameter: GET
https://www.googleapis.com/drive/v3/apps?appFilterMimeTypes=application/vnd.google-apps.form,application/vnd.google-apps.site.
languageCode: Filter the search results using a language or locale code,
as defined by BCP 47, with some extensions from Unicode's LDML
format. Examples of language codes
include en-us for English (United States) and fr-ca for French (Canada).
The following code sample shows how to provide multiple language codes as a
query parameter: GET
https://www.googleapis.com/drive/v3/apps?languageCode=en-us,fr-ca.
Get user app by ID
To download the detailed app info as an instance of
apps, use the get
method with the app ID.
The following code sample shows how to provide an appId as a query parameter in the request. The response returns the field values for the request.
Request
GET https://www.googleapis.com/drive/v3/apps/APP_ID
