Map Google drive to Owncloud
Using the Google Drive external storage in ownCloud, you can mount all or a subfolder of Google Drive.
This requires configuration through Google to get an app ID and app secret, as ownCloud registers itself as an app. All applications that access a Google API must be registered through the Google Cloud Console.
1. You can use your existing Google account such as Groups, Drive, or Mail, or create a new one and log into the Google Cloud Console. After logging in click the Create Project button on the top right side.
2. Add a new project by clicking the + button on the top right side.
3. Give your project a name, and either accept the default Project ID or create your own, then click the Create button.
4. After your project is created, click on the notifications bell and select your project.
5. Go to Api overview to select google’s API.

Configure Authorisations
These authorisations are necessary to tell Google which source URI requests are allowed. You can configure multiple Authorized URIs if you wish to enable admin and personal access at the same time for different purposes.
Authorized Redirect URIs
To configure Authorized Redirect URIs, select one of the two possible URI Schemes.
https://<your domain>/index.php/settings/admin?sectionid=storage

https://<your domain>/index.php/settings/personal?sectionid=storage
Authorized JavaScript Origins
This is just https://<your domain> which represents how you access your ownCloud server, where you see the login screen.
