Google スプレッドシート、ドキュメント、スライド、フォームのアドオンは、通常、ドキュメントにバインドされているスクリプトと同じ承認モデルに従います。ただし、特定の状況では、onOpen(e) 関数と onEdit(e) 関数が認証なしモードで実行され、さらに複雑な問題が発生します。詳しくは、アドオンの認証ライフサイクルに関するガイドをご覧ください。
OAuth アプリケーションのユーザー上限
OAuth を使用して Google ユーザーデータにアクセスするアプリケーション（Apps Script プロジェクトを含む）には、承認の上限が適用されます。詳細については、OAuth アプリケーションのユーザー上限をご覧ください。

Code that is\ncommented out can still generate an authorization request. If a script needs\nauthorization, you'll see one of the authorization dialogs shown here when it is\nrun.\n\nScripts that you have previously authorized also ask for additional\nauthorization if a code change adds new services. Scripts may not request\nauthorization if you access the script as a web app that runs under\n[the script owner's user identity](/apps-script/execution_web_apps#permissions).\n| **Warning:** Web apps and other scripts that use sensitive scopes are subject to review by Google. Users attempting to authorize such apps may see a warning screen saying the app is *unverified* by Google. See [OAuth client verification](/apps-script/guides/client-verification) for details.\n\nRevoking access rights\n\nTo revoke a script's access to your data, follow these steps:\n\n1. Visit the [permissions](https://security.google.com/settings/security/permissions) page for your Google account. (To navigate to this page in the future, visit [Google.com](https://www.google.com), then click your account picture in the top-right corner of the screen. Next, click **My Account** , then **Connected apps \\& sites** under the \"Sign-in \\& security\" section, and then **Manage Apps**.)\n2. Click the name of the script whose authorization you want to revoke, then click **Remove** on the right, then **OK** in the resulting dialog.\n\nPermissions and types of scripts\n\nThe user identity that a script runs with --- and thus the data it can access ---\nvaries based on the scenario in which the script is run, as shown in the table\nbelow.\n\n| Type of script | Script runs as... |\n|--------------------------------------------------------------------------------------------------------------------------------------------------------------------|------------------------------------------------------------------------------------------------------------------------------------------------------------------------|\n| [Standalone](/apps-script/execution_script_editor), [add-on](/workspace/add-ons/overview), or [bound to Docs, Sheets, Slides, or Forms](/apps-script/guides/bound) | User at the keyboard |\n| [Custom function in a spreadsheet](/apps-script/execution_custom_functions) | [Anonymous user](/apps-script/execution_custom_functions#permissions); however, [quota limits](/apps-script/guides/services/quotas) count against user at the keyboard |\n| [Web app](/apps-script/execution_web_apps) or [Google Sites gadget](/apps-script/execution_gadgets) | User at the keyboard or script owner, dependent on [options selected](/apps-script/execution_web_apps#permissions) when deploying the app |\n| [Installable trigger](/apps-script/understanding_triggers#Installable) | User who created the trigger |\n\nManual authorization scopes for Sheets, Docs, Slides, and Forms\n\nIf you're building an [add-on](/workspace/add-ons/overview) or other script that\nuses the [Spreadsheet service](/apps-script/reference/spreadsheet),\n[Document service](/apps-script/reference/document),\n[Slides service](/apps-script/reference/slides), or\n[Forms service](/apps-script/reference/forms), you can force the authorization\ndialog to ask only for access to files in which the add-on or script is used,\nrather than all of a user's spreadsheets, documents, or forms. To do so, include\nthe following [JsDoc](https://jsdoc.app/) annotation in a file-level comment: \n\n /**\n * @OnlyCurrentDoc\n */\n\nAn opposing annotation, `@NotOnlyCurrentDoc`, is available if your script\nincludes a [library](/apps-script/guides/libraries) that declares\n`@OnlyCurrentDoc`, but the master script actually requires access to more than\nthe current file.\n\nAuthorization lifecycle for add-ons\n\n[Add-ons](/workspace/add-ons/overview) for Google Sheets, Docs, Slides, and Forms\ngenerally follow the same authorization model as scripts that are\n[bound](/apps-script/guides/bound) to a document. In certain\ncircumstances, however, their `onOpen(e)` and `onEdit(e)` functions run in a\nno-authorization mode that presents some additional complications. For more\ninformation, see the\n[guide to the add-ons authorization lifecycle](/workspace/add-ons/concepts/addon-authorization#editor_add-on_authorization).\n\nOAuth application user limits\n\nApplications that use OAuth to access Google user data, including Apps\nScript projects, are subject to authorization limits. See\n[OAuth application user limits](https://support.google.com/cloud/answer/9028764)\nfor details."]]
