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](https://workspace.google.com/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](https://developers.google.com/workspace/meet/add-ons/guides/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](https://workspace.google.com/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](https://developers.google.com/workspace/meet/add-ons/guides/overview#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](https://developers.google.com/workspace/meet/add-ons/guides/overview#side-panel). The main stage is rendered by its own page in your
    add-on (for example,
    `https://example.com/mainStage.html`), which must call `createAddonSession`
    in JavaScript. For more information, see
    [Create a main stage page](https://developers.google.com/workspace/meet/add-ons/guides/use-SDK#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/` and `http://example.com/` don't share the same origin
    (because they use different schemes). For more information, see [Add-on
    security](https://developers.google.com/workspace/meet/add-ons/guides/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.
