アプリに付与するアクセスレベルを定義するには、承認スコープを特定して宣言する必要があります。認証スコープは、Google Workspace アプリ名、アクセスするデータの種類、アクセスレベルを含む OAuth 2.0 URI 文字列です。スコープとは、ユーザーの Google アカウント データを含む Google Workspace データを操作するためのアプリのリクエストのことです。
機密情報: これらのスコープは、ユーザーがアプリに対して承認した特定の Google ユーザーデータへのアクセスを提供します。追加のアプリ検証を受ける必要があります。この要件については、機密性の高いスコープと制限付きスコープの要件をご覧ください。
制限付き: これらのスコープは Google ユーザーデータへの広範なアクセスを提供するため、制限付きスコープの確認プロセスを完了する必要があります。この要件について詳しくは、Google API サービスのユーザーデータに関するポリシーと特定の API スコープの追加要件をご覧ください。制限付きスコープのデータをサーバーに保存（または送信）する場合は、セキュリティ評価を受ける必要があります。

Before reading this document, be sure to read the\nGoogle Workspace's general authentication and authorization information at\n[Learn about authentication and authorization](/workspace/guides/auth-overview).\n\nNote that Sheets API scopes are applied to a\n[spreadsheet](/workspace/sheets/api/guides/concepts#spreadsheet) file and cannot\nbe limited to a specific [sheet](/workspace/sheets/api/guides/concepts#sheet).\nTo prevent modification of a sheet, use a\n[`ProtectedRange`](/workspace/sheets/api/reference/rest/v4/spreadsheets/sheets#protectedrange)\nto define a cell or range of cells that cannot be edited. For an example, see\n[Named and protected ranges](/workspace/sheets/api/samples/ranges).\n\nConfigure OAuth 2.0 for authorization\n-------------------------------------\n\n[Configure the OAuth consent screen and choose scopes](/workspace/guides/configure-oauth-consent)\nto define what information is displayed to users and app reviewers, and register\nyour app so that you can publish it later.\n\nSheets API scopes\n-----------------\n\nTo define the level of access granted to your app, you need to identify and\ndeclare *authorization scopes*. An authorization scope is an OAuth 2.0 URI string\nthat contains the Google Workspace app name, what kind of data it accesses, and\nthe level of access. Scopes are your app's requests to work with Google Workspace data, including\nusers' Google Account data.\n\n\nWhen your app is installed, a user is asked to validate the scopes used\nby the app. Generally, you should choose the most narrowly focused scope\npossible and avoid requesting scopes that your app doesn't require. Users more\nreadily grant access to limited, clearly described scopes.\n\nWhen possible, we recommend using non-sensitive scopes as it grants per-file\naccess scope and narrows access to specific features needed by an app.\n| If your public application uses scopes that permit access to certain user data, it must complete a verification process. If you see **unverified\n| app** on the screen when testing your application, you must submit a verification request to remove it. Find out more about [unverified apps](https://support.google.com/cloud/answer/7454865) and get answers to [frequently asked questions about app verification](https://support.google.com/cloud/answer/9110914) in the Help Center.\n\nThe Sheets API supports the following scopes:\n\n| Scope code | Description | Usage |\n|---------------------------------------------------------|-------------------------------------------------------------------------------------------|---------------------------|\n| `https://www.googleapis.com/auth/spreadsheets` | See, edit, create, and delete all your Google Sheets spreadsheets. | Sensitive |\n| `https://www.googleapis.com/auth/spreadsheets.readonly` | See all your Google Sheets spreadsheets. | Sensitive |\n| `https://www.googleapis.com/auth/drive.file` | See, edit, create, and delete only the specific Google Drive files you use with this app. | Recommended Non-sensitive |\n| `https://www.googleapis.com/auth/drive` | See, edit, create, and delete all of your Google Drive files. | Restricted |\n| `https://www.googleapis.com/auth/drive.readonly` | See and download all your Google Drive files. | Restricted |\n\nThe Usage column in the table indicates the sensitivity of each scope, according\nto the following definitions:\n\n- **Non-sensitive** : These scopes provide the smallest scope of authorization\n access and only requires basic app verification. For information on this\n requirement, see [Submitting your app for\n verification](https://support.google.com/cloud/answer/13461325).\n\n- **Sensitive** : These scopes provide access to specific Google User Data\n that's authorized by the user for your app. It requires you to go through\n additional app verification. For information on this requirement, see\n [Sensitive and Restricted Scope\n Requirements](https://support.google.com/cloud/answer/13464321#ss-rs-requirements).\n\n- **Restricted** : These scopes provide wide access to Google User Data and\n require you to go through a restricted scope verification process. For\n information on this requirement, see [Google API Services User Data\n Policy](/terms/api-services-user-data-policy) and [Additional Requirements\n for Specific API\n Scopes](/terms/api-services-user-data-policy#additional_requirements_for_specific_api_scopes).\n If you store restricted scope data on servers (or transmit), then you must\n go through a security assessment.\n\nIf your app requires access to any other Google APIs, you can add those scopes\nas well. For more information about Google API scopes, see [Using OAuth 2.0 to\nAccess Google APIs](/identity/protocols/oauth2).\n\nFor more information about specific OAuth 2.0 scopes, see [OAuth 2.0 Scopes for\nGoogle APIs](/identity/protocols/oauth2/scopes).\n\nRelated topics\n--------------\n\n- [Choose Google Drive API scopes](/workspace/drive/api/guides/api-specific-auth)\n- [OAuth App Verification Help Center](https://support.google.com/cloud/answer/13463073)\n- [OAuth App Verification FAQs](https://support.google.com/cloud/answer/13463817)"]]
