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 theGoogle 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, seeConcepts.
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
TheMarketplaceoffers 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 theside panelor 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 theside
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, seeCreate 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, seeAdd-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.
