The *Google Workspace Marketplace SDK* is a toolkit that lets you create and
control your *app listing* on the *Google Workspace Marketplace*, or for
Chat apps, in Google Chat.

The
*[Google Workspace Marketplace](https://workspace.google.com/marketplace/)* is
a website that lists Google Workspace add-ons, Editor add-ons,
Drive apps, and Web apps that are integrated with
Google Workspace, such as security, CRM, document management, and project
management tools.

An *app listing* is the collection of text, graphics, and *app integrations*
that describe your application and determine how it surfaces within
Google Workspace. Google doesn't charge a listing fee to distribute apps
through the Marketplace.

## App integrations

App integrations determine how and where users interact with your app in
Google Workspace. For example, a Google Sheets add-on is accessible from
Sheets and extends the functionality of Sheets.
Your app must support an integration with one or more [Google Workspace
Services](https://workspace.google.com/intl/en/terms/user_features/).

You can publish an app listing on Marketplace for the
following app integrations:

- Google Workspace add-ons
- Editor add-ons
- Google Drive apps
- Google Chat apps
- Google Classroom add-ons
- Web apps

To learn more about the types of apps you can build and publish, see
[Extend the Google Workspace UI](https://developers.google.com/workspace/extend).

### List app integrations together

Some app integrations can be combined in your app listing. For example, if your
app enhances the functionality of Sheets and is also accessible
as a web app, you can publish an app listing that includes a
Sheets add-on and a web app that's added to the Google apps menu
across Google Workspace
products.
