Integration of Marketplace apps with Google Apps data

The third-party apps available in the Google Apps Marketplace and through your Admin console can integrate with your Google Apps data in a number of different ways.

The sections below describe each integration point, with links to get more information about each one.

Mail integration

Apps that integrate with mail have access to your Gmail data.

Two common methods of mail integration are via sidebar gadgets and contextual gadgets.

Sidebar gadgets are simple HTML and JavaScript web applications that can be embedded in the left-hand pane of Gmail. These gadgets can extend Gmail with additional functionality and content-rich data displays.

Contextual gadgets draw information from the web based on the contents of an email message. For example, contextual gadgets can display content previews based on links in a message.

Contextual gadgets make use of the following APIs:

  • Extractor APIs: Contextual gadgets use this API to detect contextual clues in email, determine which types of content trigger the gadget, and pass the triggering content to the gadget. Learn more

  • IMAP over OAuth API: Gmail supports the IMAP protocol for accessing and sending messages. This API lets the gadget have IMAP access to Gmail via OAuth. Learn more

  • GMAIL Atom Feeds API: Contextual gadgets use this API to feed updates from websites, blogs, and Gmail. Learn more

 

If you install an application that uses contextual gadgets, we recommend that you alert your users to the possibility that the gadgets can respond to the content of their email messages.

Reminder: Domain administrators should evaluate gadgets carefully before installing. Learn more

Single Sign-On

Apps that integrate with Single Sign-On allow users to securely sign in to the apps using their Google Apps credentials. This can be done in a few ways:

OAuth2 is an open protocol that allows secure authorization in a simple and standard method. All new apps available through the admin console will use Oauth2 for Single Sign-On. Learn more

SAML Single Sign-On allows secure web domains to exchange user-authentication and user-authorization data. Using SAML, an online service provider can contact a separate online identity provider to authenticate users who are trying to access secure content. Learn more

Drive

Apps that integrate with Google Drive are able to programmatically access and manipulate user data stored with Google Drive files, including Google Docs, Sheets, and Slides. For example:

  • Retrieve documents that match specific keywords, categories, or metadata
  • Modify the sharing permissions of documents and folders
  • Review, download, or publish a document’s revision history
  • Export documents
  • Create online backups of local documents, spreadsheets, presentations, and PDFs
