The Google Meet add-ons SDK lets you embed your app into Google Meet as an add-on where users can discover, share, and collaborate in the app without leaving Meet.
Developers can register their app in the Google Workspace Marketplace , through which users and administrators can search for, discover, and install add-ons. Users can also discover and install apps directly from the Meet UI.
For more information about add-ons and the Marketplace, see Concepts .
The following is a list of common terms used in this SDK:
- Add-ons
- Customized apps that integrate with Google Workspace apps.
- Available add-ons
- Add-on that's available in the Marketplace but not installed by users.
- Google Workspace Marketplace
- The Marketplace offers users and administrators a way to find and install third-party enterprise apps that are integrated with Google Workspace. It's the central place for managing published Google Workspace add-ons.
- Installable add-ons
- An add-on that users can install through the side panel or through the Marketplace.
- Installed add-ons
- Add-ons that are installed and ready for use. These are listed in a user's add-ons side panel. User's cannot uninstall admin-installed apps.
- Main stage
- The central focus area where the meeting is held. An
add-on can open on the main stage to display
content that needs more space than what's available in the side
panel 
. The main stage is rendered by its own page in your
add-on (for example, https://example.com/mainStage.html), which must callcreateAddonSessionin JavaScript. For more information, see Create a main stage page .
- Origin
- A URL with a scheme (protocol), host (domain), and port. Two URLs have the
same origin when they share the same scheme, host, and port. For example, https://example.com/andhttp://example.com/don't share the same origin (because they use different schemes). For more information, see Add-on security .
- Region Capture screen sharing
- Allows Meet to crop the video track and remove some content from it before sharing it remotely.
- Screen sharing
- The act of showing a screen, window, or browser tab to others in a call or the contents of screen sharing.
- Side panel
- The vertical panel on the right side of the meeting space. This initially displays the installed add-ons for selection. Once an add-on is selected, the side panel displays the entry point page for your add-on app.
