Help us improve our Google Workspace documentation by taking a quick [online survey](https://forms.gle/XcqRP3PJiQv9ADuj9). |\n\nThe Google Meet add-ons SDK lets you embed your app into Google Meet as an\nadd-on where users can discover, share, and collaborate\nin the app without leaving Meet.\n\nDevelopers can register their app in the\n[Google Workspace Marketplace](https://workspace.google.com/marketplace/)\n, through which users and administrators can search for, discover, and install\nadd-ons. Users can also discover and install apps directly from\nthe Meet UI.\n\nFor more information about add-ons and the\nMarketplace, see\n[Concepts](/workspace/meet/add-ons/guides/concepts).\n\n\u003cbr /\u003e\n\n| **Note:** Third-party cookies in the Chrome browser are **no longer being\n| deprecated** . Development of Google Meet add-ons shouldn't be impacted for the near future. However, Chrome intends to further elevate user choice around third-party cookies so third-party cookie access might become more limited in the future than it is today. For more information, see the [blog\n| post](https://privacysandbox.com/news/privacy-sandbox-update/) announcement.\n\nThe following is a list of common terms used in this SDK:\n\n*Add-ons*\n: Customized apps that integrate with Google Workspace apps.\n\n*Available add-ons*\n: Add-on that's\n available in the Marketplace but not installed by\n users.\n\n*Google Workspace Marketplace*\n: The\n [Marketplace](https://workspace.google.com/marketplace/)\n offers users and administrators a way to find and install third-party\n enterprise apps that are integrated with Google Workspace. It's the\n central place for managing published Google Workspace add-ons.\n\n*Installable add-ons*\n: An add-on that\n users can install through the [side panel](#side-panel) or through the\n Marketplace.\n\n*Installed add-ons*\n: Add-ons that are installed\n and ready for use. These are listed in a user's add-ons side\n panel. User's cannot uninstall admin-installed apps.\n\n*Main stage*\n: The central focus area where the meeting is held. An\n add-on can open on the main stage to display\n content that needs more space than what's available in the [side\n panel](#side-panel). The main stage is rendered by its own page in your\n add-on (for example,\n `https://example.com/mainStage.html`), which must call `createAddonSession`\n in JavaScript. For more information, see\n [Create a main stage page](/workspace/meet/add-ons/guides/use-SDK#create_a_main_stage_page).\n\n*Origin*\n: A URL with a scheme (protocol), host (domain), and port. Two URLs have the\n same origin when they share the same scheme, host, and port. For example,\n `https://example.com/` and `http://example.com/` don't share the same origin\n (because they use different schemes). For more information, see [Add-on\n security](/workspace/meet/add-ons/guides/add-on-security).\n\n*Region Capture screen sharing*\n: Allows Meet to crop the video track and remove some content\n from it before sharing it remotely.\n\n*Screen sharing*\n: The act of showing a screen, window, or browser tab to others in a call or the\n contents of screen sharing.\n\n*Side panel*\n: The vertical panel on the right side of the meeting space. This initially\n displays the installed add-ons for selection. Once an\n add-on is selected, the side panel displays the\n entry point page for your add-on app.\n**Figure 1.** The Meet add-ons SDK main stage and side panel.\n\nRelated topics\n--------------\n\n- To learn how to create an add-on, follow the\n example in [Deploy a\n Meet add-on](/workspace/meet/add-ons/guides/deploy-add-on).\n\n- To learn how to use the Meet add-ons SDK, follow the example in\n [Use the Meet add-ons SDK](/workspace/meet/add-ons/guides/use-SDK).\n\n- To learn how to collaborate in an add-on, follow\n the example in [Collaborate using a\n Meet add-on](/workspace/meet/add-ons/guides/collaborate-in-the-add-on).\n\n- To implement either the Co-Doing API or Co-Watching API,\n see [Implement the\n Co-Doing API](/workspace/meet/add-ons/guides/use-CoDoingAPI) and [Implement\n the Co-Watching API](/workspace/meet/add-ons/guides/use-CoWatchingAPI).\n\n- To learn about deploying and sharing your\n Meet add-on with others, see [Publish your\n Meet add-on](/workspace/meet/add-ons/guides/publish).\n\n- To learn about developing with Google Workspace APIs, refer to [Get started as\n a Google Workspace\n developer](/workspace/guides/getstarted-overview)."]]
