Marketplace 中的 Google Workspace 插件
Google Workspace 加购项是与 Google Workspace 应用(例如 Gmail、Google 文档和 Google 表格)集成的自定义应用。它们可让开发者创建直接集成到 Google Workspace 中的自定义界面。插件可帮助用户更高效地工作,减少上下文切换。
Google Workspace Marketplace 可让用户和管理员找到并安装与 Google Workspace 集成的第三方企业应用。Marketplace 也是管理已发布的 Google Workspace 加购项的中心位置。用户可以安装和卸载已发布的插件。管理员可以限制用户可以安装的插件。

This indicates to Meet that the add-on is loaded and is ready for use.\n5. **Add-on initialized**: The add-on is ready for use.\n6. **(Optional) Request token with One Tap** : The selected add-on uses [Google One Tap](/identity/gsi/web/guides/display-google-one-tap) to request a token with the sign-in information and user-approved scopes if there's an active Google session.\n7. **(Optional) Google returns ID token**: The ID token contains the user identity information.\n\nGoogle Workspace add-ons in the Marketplace\n-------------------------------------------\n\nGoogle Workspace add-ons are customized apps that integrate with Google Workspace\napplications, such as Gmail, Google Docs, and Google Sheets. They\nallow developers to create customized user interfaces that are directly\nintegrated into Google Workspace. Add-ons help users work more\nefficiently with less context switching.\n\nThe [Google Workspace Marketplace](https://workspace.google.com/marketplace/)\noffers users and administrators a way to find and install third-party enterprise\napps that are integrated with Google Workspace. The\nMarketplace is also the central place for managing\npublished Google Workspace add-ons. Users can install and uninstall published\nadd-ons. Admins can restrict the add-ons users can\ninstall.\n\nTypes of add-ons\n----------------\n\nIn general, there are two types of add-ons you can build: [Google Workspace add-ons](/apps-script/add-ons/concepts/types#google-workspace-add-ons)\nand\n[Editor add-ons](/apps-script/add-ons/concepts/types#editor-add-ons).\n\nFor the Meet add-ons SDK, you must build your add-ons\nusing Google Workspace add-ons.\n\nWith a Google Workspace add-on, you can extend multiple Google Workspace\napps such as Gmail, Google Calendar, and Google Drive. You specify\nwhich app the add-on is targeting, along with other\ndetails, in the [add-on manifest\nfile](/apps-script/add-ons/concepts/workspace-manifests). For the\nMeet add-ons SDK, you must declare a `meet` object within the `addOns`\nsection of the manifest file. For more information, see [Create a\ndeployment](/workspace/meet/add-ons/guides/deploy-add-on#create-deployment).\n\nA Google Workspace add-on can be developed in two different ways: either in\nGoogle Apps Script, or as a self-hosted add-on using\nyour preferred tech stack. Each of these add-ons contains a\nmanifest, which is made up of different sections. The Meet\nsection of the manifest contains information specific to how your\nadd-on is loaded from Google Meet and is unrelated to\nwhether the rest of your add-on is self-hosted or uses\nApps Script. Add-ons for Meet are\nloaded in an iframe and must reference web pages rather than [Card-based\ninterfaces](/apps-script/add-ons/concepts/card-interfaces).\n\nFor example, a manifest for a Google Workspace add-on might have a section for\nGmail that uses\n[`ComposeTrigger`](/apps-script/manifest/gmail-addons#composetrigger) and\n[`ContextualTrigger`](/apps-script/manifest/gmail-addons#contextualtrigger)\nobjects to return card interfaces, and a section for Meet that\nuses web, iOS, and Android objects to point to your web page and mobile app.\n**Figure 2.** An example manifest with Meet and Gmail sections.\n\nPublish an add-on\n-----------------\n\nWhen you publish your Google Workspace add-on, you make it available for\nothers to find, install, and use.\n\nFor more information, see [Publish your\nMeet add-on](/workspace/meet/add-ons/guides/publish).\n\nRelated topics\n--------------\n\n- [Deploy a Meet add-on](/workspace/meet/add-ons/guides/deploy-add-on)\n- [Best practices](/workspace/meet/add-ons/guides/best-practices)\n- [Add-ons types](/apps-script/add-ons/concepts/types)\n- [Gmail manifest resource](/apps-script/manifest/gmail-addons)"]]
