OAuth 2 Google service
Features requiring the OAuth 2 Google service
You will need to set up an OAuth 2 Google service in order to use the following features:
- Google Drive repository
- OAuth 2 authentication for enabling users to log in to Moodle with their Google account
- Google Drive converter for converting assignment submission files to PDF for teachers to annotate
OAuth 2 Google service setup
To set up an OAuth 2 client with Google, log in to the Google Developers Console and click the arrow by 'Select a project'.
Click 'Create a new project'
Give it a name. The name is not visible to anyone so you can choose any name you like.
Click Credentials from the menu on the left.
Setup the consent screen for your application. This is where you provide the public information that is shown to users when they are asked to authorise your application. Setting a product name is the minimum information that is required, but the more information you provide here - the more confidence users will have when granting this authorisation.
Now you can create some client credentials. Click Credentials from the menu on the left again then click "+ Create credentials" and select OAuth client ID.
Select Web application as Application type and click to add an authorised redirect URI. This must be set to "your moodle site url + /admin/oauth2callback.php". If your Moodle site was accessible at https://lemon.edu/ then this callback URL should be set to https://lemon.edu/admin/oauth2callback.php. Enter the URL then click Create.
When you have saved the information on this page, Google will give you the client ID and client secret that you need to enter into Moodle.
Finally we have to enable the Drive API (if we want to use the google drive repository or file converter plugins).
Click Library from the menu on the left.
Search for drive and select Google Drive API. Click the Enable button.
NOTE: If you are just using this for document conversion you will not need to verify (as it only uses one account). You will, however, need to verify your ownership of your domain (see Verify your site ownership - Search Console Help.)
The Google Drive repository and Google Drive converter also require the app to be verified by completing the OAuth Developer Verification Form. The list of scopes that Moodle requires are:
openid profile email https://www.googleapis.com/auth/drive.
