The returned values are measured\nin bytes.\n\nYou *must* set the `fields` [system\nparameter](https://cloud.google.com/apis/docs/system-parameters#definitions) on\nthe `get` method to specify the fields to return in the response. In most\nDrive methods this action is only required to return non-default\nfields but it's mandatory for the `about` resource. If you omit the parameter,\nthe method returns an error. For more information, see [Return specific fields](/workspace/drive/api/guides/fields-parameter).\n| **Note:** If you're using the previous Drive API v2 version, setting the `fields` parameter in the `get` method isn't required. Learn how to [migrate to\nDrive API v3](/workspace/drive/api/guides/migrate-to-v3). \nThe 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.\n\n**Request** \n\n```text\nGET https://www.googleapis.com/drive/v3/about/?fields=kind,user,storageQuota\n```\n\n**Response** \n\n```scdoc\n{\n \"kind\": \"drive#about\",\n \"user\": {\n \"kind\": \"drive#user\",\n \"displayName\": \"DISPLAY_NAME\",\n \"photoLink\": \"PHOTO_LINK\",\n \"me\": true,\n \"permissionId\": \"PERMISSION_ID\",\n \"emailAddress\": \"EMAIL_ADDRESS\"\n },\n \"storageQuota\": {\n \"usage\": \"10845031958\",\n \"usageInDrive\": \"2222008387\",\n \"usageInDriveTrash\": \"91566\"\n }\n}\n```\n\nThe response includes the following values:\n\n- \u003cvar translate=\"no\"\u003eDISPLAY_NAME\u003c/var\u003e: the user's name in plain text.\n- \u003cvar translate=\"no\"\u003ePHOTO_LINK\u003c/var\u003e: the URL of the user's profile photo.\n- \u003cvar translate=\"no\"\u003ePERMISSION_ID\u003c/var\u003e: the user's ID within the `Permission` resources.\n- \u003cvar translate=\"no\"\u003eEMAIL_ADDRESS\u003c/var\u003e: the user's email address\n\nList user apps\n\nGoogle Drive apps are listed in the\n[Google Workspace Marketplace](https://workspace.google.com/marketplace) and\nare used to make Drive more convenient such as the Google Docs\napp or an add-on used within Docs to\nsign documents. For more information, see [Use Google Drive\napps](https://support.google.com/drive/answer/2500820).\n\nTo return a list of all the user's installed apps as an instance of [`apps`](/workspace/drive/api/reference/rest/v3/apps), use the [`list`](/workspace/drive/api/reference/rest/v3/apps/list) method\nwithout any parameters.\n\nIf you want to specify the fields to return in the response, you can set the\n`fields` [system\nparameter](https://cloud.google.com/apis/docs/system-parameters#definitions). If\nyou don't specify the `fields` parameter, the server returns a default set of\nfields. For more information, see [Return specific fields](/workspace/drive/api/guides/fields-parameter).\n| **Note:** If you're using the previous Drive API v2 version, the response body also includes the `etag` field. Learn how to [migrate to\nDrive API v3](/workspace/drive/api/guides/migrate-to-v3). \nThe 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.\n\n**Request** \n\n```text\nGET https://www.googleapis.com/drive/v3/apps\n```\n\n**Response** \n\n```scdoc\n{\n \"kind\": \"drive#appList\",\n \"selfLink\": \"https://www.googleapis.com/drive/v3/apps\",\n \"items\": [\n {\n \"kind\": \"drive#app\",\n \"id\": \"ID\",\n \"name\": \"Google Sheets\",\n \"supportsCreate\": true,\n \"supportsImport\": true,\n \"supportsMultiOpen\": false,\n \"supportsOfflineCreate\": true,\n \"productUrl\": \"https://chrome.google.com/webstore/detail/felcaaldnbdncclmgdcncolpebgiejap\",\n \"productId\": \"PRODUCT_ID\"\n }\n ],\n \"defaultAppIds\": [\n \"ID\"\n ]\n}\n```\n\nThe response includes the following values:\n\n- \u003cvar translate=\"no\"\u003eID\u003c/var\u003e: the app ID.\n- \u003cvar translate=\"no\"\u003ePRODUCT_ID\u003c/var\u003e: the product listing ID for this app.\n\nList user apps with query parameters\n\nTo find a specific app, use one or more of the optional query parameters:\n\n- `appFilterExtensions`: Filter the search results using a comma-separated\n list of file extensions. Apps within the app query scope that can open the\n listed file extensions are included in the response. If `appFilterMimeTypes`\n are also provided, a union of the two resulting app lists is returned.\n Examples of extensions include `docx` for Microsoft Word and `pptx` for\n Microsoft PowerPoint. For more examples of file extensions, see [Export MIME\n types for Google Workspace documents](/workspace/drive/api/guides/ref-export-formats).\n\n The following code sample shows how to provide multiple file extensions as a\n query parameter: `GET\n https://www.googleapis.com/drive/v3/apps?appFilterExtensions=docx,pptx`.\n- `appFilterMimeTypes`: Filter the search results using a comma-separated list\n of MIME types. Apps within the app query scope that can open the listed MIME\n types are included in the response. If `appFilterExtensions` are also\n provided, a union of the two resulting app lists is returned. Examples of\n MIME types include `application/vnd.google-apps.form` for Google Forms and\n `application/vnd.google-apps.site` for Google Sites. For more examples of\n MIME types, see [Google Workspace and Google Drive supported MIME\n types](/workspace/drive/api/guides/mime-types).\n\n The following code sample shows how to provide multiple MIME types as a\n query parameter: `GET\n https://www.googleapis.com/drive/v3/apps?appFilterMimeTypes=application/vnd.google-apps.form,application/vnd.google-apps.site`.\n- `languageCode`: Filter the search results using a language or locale code,\n as defined by BCP 47, with some extensions from [Unicode's LDML\n format](https://www.unicode.org/reports/tr35/). Examples of language codes\n include `en-us` for English (United States) and `fr-ca` for French (Canada).\n\n The following code sample shows how to provide multiple language codes as a\n query parameter: `GET\n https://www.googleapis.com/drive/v3/apps?languageCode=en-us,fr-ca`.\n\nGet user app by ID\n\nTo download the detailed app info as an instance of\n[`apps`](/workspace/drive/api/reference/rest/v3/apps), use the [`get`](/workspace/drive/api/reference/rest/v3/apps/get)\nmethod with the app ID. \nThe 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.\n\n**Request** \n\n```scdoc\nGET https://www.googleapis.com/drive/v3/apps/APP_ID\n```\n\n**Response** \n\n```scdoc\n{\n \"kind\": \"drive#app\",\n \"id\": \"ID\",\n \"name\": \"Google Sheets\",\n \"supportsCreate\": true,\n \"supportsImport\": true,\n \"supportsMultiOpen\": false,\n \"supportsOfflineCreate\": true,\n \"productUrl\": \"https://chrome.google.com/webstore/detail/felcaaldnbdncclmgdcncolpebgiejap\",\n \"productId\": \"PRODUCT_ID\"\n}\n```\n\nThe response includes the following values:\n\n- \u003cvar translate=\"no\"\u003eID\u003c/var\u003e: the app ID.\n- \u003cvar translate=\"no\"\u003ePRODUCT_ID\u003c/var\u003e: the product listing ID for this app.\n\nRelated topics\n\nHere are a few next steps you might try:\n\n- To create a file in Drive, see [Create and manage files](/workspace/drive/api/guides/create-file).\n\n- To upload file data when you create or update a file, see [Upload file\n data](/workspace/drive/api/guides/manage-uploads).\n\n- To download and export files, see [Download and export\n files](/workspace/drive/api/guides/manage-downloads)."]]
