Enabling 3rd Party Apps for Google Drive
To use Pear Deck with a Google Apps for Education domain, we require that the domain allow 3rd party apps to be installed on Google Drive (enabled by default in the Google Admin Console) OR that the administrator install Pear Deck from the Google Apps Marketplace.
If your domain currently disallows 3rd party apps, your Google Apps IT Administrator must perform the following steps to re-enable apps:
To enable third-party Google Drive apps:
- Sign in to the Google Admin console
- Click Apps > Google Apps > Drive > Data Access.
- If you have the Google Apps Unlimited, Education, or Nonprofits edition, select the desired organizational unit. (Learn about Google Apps editions.)
Otherwise, your settings apply to your entire organization.
- Check Allow users to install Google Drive apps.
This setting affects only third-party apps from the Chrome web store. If you don't check this option, apps from Google (such as Docs, Drive, Slides, Forms, and Drawings) are still available.
- Click Save Changes.
In addition, Google Apps Marketplace applications can still be installed by administrators. You can therefore whitelist Pear Deck for your organization by disabling the option above for your users and deploying specific Marketplace apps (like Pear Deck) as the administrator.
