Note: There's a new Google Apps Marketplace experience! Beginning November 19, 2013, new listings may only be created using the new version: existing developers may need to create a new Chrome Web Store account to publish new listings. Refer to the new documentation for more information.
This tutorial will walk you through launching your first application on the Google Apps Marketplace. It assumes you already can create a basic "Hello World" web application and builds on top of such an application to demonstrate several key pieces of functionality -- a link in the Google universal navigation, Single Sign On using OpenID and OAuth-enabled access to Google Apps data. Instead of saying "Hello World", the application will greet the Google Apps user by name and shows them their next Google Calendar appointment.
The tutorial assumes that you are a developer with a high level understanding of web technologies such as XML and HTTP.
