[null,null,["อัปเดตล่าสุด 2025-08-29 UTC"],[],[],null,["| **Note:** This is a **beta release** of the Google Picker API for desktop apps.\n\nThe Google Picker API is a way to let users select or upload Google Drive files.\nUsers can grant permission to your desktop apps to access their\nDrive data, providing a secure and authorized way to interact\nwith their files.\n\nThe Google Picker acts as a \"File Open\" dialog for files stored on\nDrive and has several features:\n\n- A similar look and feel to the [Google Drive\n UI](https://drive.google.com).\n- Several views showing previews and thumbnail images of Drive files.\n- A redirect to the Google Picker within a new tab in the user's default browser.\n\nNote that the Google Picker doesn't allow users to organize, move, or copy\nfiles from one folder to another. To manage files, you must use either the [Google Drive API](/workspace/drive/api/guides/about-sdk) or the Drive UI.\n\nPrerequisites\n\nApps using the Google Picker must abide by all existing [Terms of\nService](/workspace/terms). Most importantly, you must correctly identify\nyourself in your requests.\n\nYou must also have a [Google Cloud project](/workspace/guides/create-project).\n\nSet up your environment\n\nTo start using the Google Picker API, you must set up your environment.\n\nEnable the API Before using Google APIs, you need to turn them on in a Google Cloud project. You can turn on one or more APIs in a single Google Cloud project.\n\n- In the Google Cloud console, enable the Google Picker API.\n\n [Enable the API](https://console.cloud.google.com/flows/enableapi?apiid=picker.googleapis.com)\n\nCreate an API key\n\nAn API key is a long string containing upper and lower case letters, numbers,\nunderscores, and hyphens, such as `AIzaSyDaGmWKa4JsXZ-HjGw7ISLn_3namBGewQe`.\nThis authentication method is used to anonymously access publicly available\ndata, such as Google Workspace files shared using the \"Anyone on the Internet\nwith this link\" sharing setting. For more details, see [Manage API\nkeys](https://cloud.google.com/docs/authentication/api-keys).\n\nTo create an API key:\n\n1. In the Google Cloud console, go to Menu menu \\\u003e **APIs \\& Services** \\\u003e **Credentials** .\n\n [Go to Credentials](https://console.cloud.google.com/apis/credentials)\n2. Click **Create credentials** \\\u003e **API key**.\n3. Your new API key is displayed.\n - Click Copy content_copy to copy your API key for use in your app's code. The API key can also be found in the \"API Keys\" section of your project's credentials.\n - To prevent unauthorized use, we recommend restricting where and for which APIs the API key can be used. For more details, see [Add API restrictions](https://cloud.google.com/docs/authentication/api-keys#adding-api-restrictions).\n\nAuthorize credentials for a desktop app To authenticate end users and access user data in your app, you need to create one or more OAuth 2.0 Client IDs. A client ID is used to identify a single app to Google's OAuth servers. If your app runs on multiple platforms, you must create a separate client ID for each platform.\n\n1. In the Google Cloud console, go to Menu menu \\\u003e **Google Auth platform** \\\u003e **Clients** .\n\n [Go to Clients](https://console.cloud.google.com/auth/clients)\n2. Click **Create Client**.\n3. Click **Application type** \\\u003e **Desktop app**.\n4. In the **Name** field, type a name for the credential. This name is only shown in the Google Cloud console.\n5. Click **Create** .\n\n\n The newly created credential appears under \"OAuth 2.0 Client IDs.\"\n\nFor apps to get authorization to files previously granted to them, you must use\nthe following steps:\n\n1. You must obtain an OAuth 2.0 token with the `drive.file`, `drive`, or\n `drive.readonly` scope using these instructions: [Using OAuth 2.0 to Access\n Google APIs](/identity/protocols/oauth2). For more information on scopes,\n see [Choose Google Drive API scopes](/workspace/drive/api/guides/api-specific-auth).\n\n2. Pass the OAuth 2.0 token to the Drive API to read and modify files\n in which the user previously granted access.\n\nDisplay the Google Picker\n\nThe Google Picker API for desktop apps redirects to the Google Picker within a\nnew tab in the user's default browser. Once the user grants access and picks the\nrelevant files, the Google Picker returns to the calling app through the\ncallback URL. To have the Google Picker API open in a client page, use the\nGoogle Picker API for web apps instead. For more information, see [Overview of web\napps](/workspace/drive/picker/guides/overview).\n\nTo allow users to grant access to additional files or to pick files for use in\nyour desktop app flow, follow these steps:\n\n1. Request access to the `drive.file` scope to open the OAuth 2.0 access page\n in a new browser tab using these instructions: [Using OAuth 2.0 to Access\n Google APIs](/identity/protocols/oauth2). For more information on scopes,\n see [Choose Google Drive API scopes](/workspace/drive/api/guides/api-specific-auth).\n\n Note that only the `drive.file` scope is permitted for desktop apps and it\n can't be combined with any other scope.\n2. The URL for the new browser tab accepts all [standard OAuth query string\n parameters](/identity/protocols/oauth2/native-app#step-2:-send-a-request-to-googles-oauth-2.0-server).\n\n You must append the `prompt` and `trigger_onepick` URL parameters to your\n OAuth 2.0 authorization URL request. You can also customize the\n Google Picker with several optional parameters:\n\n | Parameter | Description | Status |\n |-------------------------------------------------|------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|----------|\n | `prompt=consent` | Prompt for file access. | Required |\n | `trigger_onepick=true` | Enable the Google Picker. | Required |\n | `allow_multiple=true` | If true, allow the user to select multiple files. | Optional |\n | `mimetypes=`\u003cvar translate=\"no\"\u003eMIMETYPES\u003c/var\u003e | A comma-separated list of [MIME types](/workspace/drive/api/guides/mime-types) to filter the search results. If not set, files for all MIME types are displayed in the view. | Optional |\n | `file_ids=`\u003cvar translate=\"no\"\u003eFILE_IDS\u003c/var\u003e | A comma-separated list of file IDs to filter the search results. If not set, all files are displayed in the view. | Optional |\n\n The following sample shows an OAuth 2.0 authorization URL request: \n\n https://accounts.google.com/o/oauth2/v2/auth? \\\n client_id=\u003cvar translate=\"no\"\u003eCLIENT_ID\u003c/var\u003e \\\n &scope=https://www.googleapis.com/auth/drive.file \\\n &redirect_uri=\u003cvar translate=\"no\"\u003eREDIRECT_URI\u003c/var\u003e \\\n &response_type=code \\\n &access_type=offline \\\n &prompt=consent \\\n &trigger_onepick=true\n\n Replace the following:\n - \u003cvar translate=\"no\"\u003eCLIENT_ID\u003c/var\u003e: Your desktop app's client ID.\n\n - \u003cvar translate=\"no\"\u003eREDIRECT_URI\u003c/var\u003e: Where the authorization server\n redirects the user's browser after successful authentication. For\n example, `https://www.cymbalgroup.com/oauth2callback`.\n\n The specified `redirect_uri` must be a public HTTPS URL. If you want to use\n a custom protocol or localhost URL for your `redirect_uri`, you must use a\n public HTTPS URL that then redirects to the custom protocol or localhost\n URL.\n3. Once the user grants access and picks the relevant files, OAuth redirects to\n the `redirect_uri` specified in the request with the following URL\n parameters appended:\n\n - `picked_file_ids`: If the user granted access and picked files, a\n comma-separated list of selected file IDs.\n\n - `code`: The access token or access code based on the `response_type`\n parameter set in the request. This parameter includes a new\n [authorization code](/identity/protocols/oauth2#installed).\n\n - `scope`: The scope(s) included in the request.\n\n - `error`: If the user cancelled the request within the consent flow, an\n error is shown.\n\n The following sample shows an OAuth 2.0 authorization URL response: \n\n https://\u003cvar class=\"readonly\" translate=\"no\"\u003eREDIRECT_URI\u003c/var\u003e?picked_file_ids=\u003cvar class=\"readonly\" translate=\"no\"\u003ePICKED_FILE_IDS\u003c/var\u003e&code=\u003cvar class=\"readonly\" translate=\"no\"\u003eCODE\u003c/var\u003e&scope=\u003cvar class=\"readonly\" translate=\"no\"\u003eSCOPES\u003c/var\u003e\n\n4. Apps must exchange the authorization code from step 3 for a new OAuth 2.0\n token. For more information, see [Exchange authorization code for refresh\n and access\n tokens](/identity/protocols/oauth2/web-server#exchange-authorization-code).\n\n5. Apps can then use the file IDs from the URL parameter in step 3 and OAuth\n 2.0 token obtained in step 4 to call the Drive API. For more\n information, see [Google Drive API overview](/workspace/drive/api/guides/about-sdk)."]]
