Set up a project in the Google API Console

Visit the Google API Console and sign in with your Google account.
Click the Select a project button on the top menu bar, and click the New Project button to create a project.
In your newly created project, click the APIs & Services to enter the APIs & Services menu.

Configure your consent screen

Configure and register your application

On the left APIs & Services menu, click the OAuth consent screen button.
Choose the User Type you want, and click the Create button. (Note: If you select External as your User Type, you will need to add test users later.)

Now you will be on the Edit app registration page.

Edit app registration

Config OAuth consent screen

Follow the instructions to fill out the OAuth consent screen form.
Click SAVE AND CONTINUE to continue.

Config scopes

Click ADD OR REMOVE SCOPES and select ../auth/userinfo.email, ../auth/userinfo.profile and openid in the popup drawer, and click UPDATE to finish. It is recommended that you consider adding all the scopes you may use, otherwise some scopes you added in the configuration may not work.
Fill out the form as you need.
Click SAVE AND CONTINUE to continue.

Add test users (External user type only)

Click ADD USERS and add test users to allow these users to access your application while testing.
Click SAVE AND CONTINUE to continue.

Now you should have the Google OAuth 2.0 consent screen configured.

Obtain OAuth 2.0 credentials

On the left APIs & Services menu, click the Credentials button.
On the Credentials page, click the + CREATE CREDENTIALS button on the top menu bar, and select OAuth client ID.
On the Create OAuth client ID page, select Web application as the application type.
Fill out the basic information for your application.
Click + Add URI to add an authorized domain to the Authorized JavaScript origins section. This is the domain that your logto authorization page will be served from. In our case, this will be ${your_logto_origin}. e.g.https://logto.dev.
Click + Add URI in the **Authorized redirect URIs** section to set up the **Authorized redirect URIs**, which redirect the user to the application after logging in. In our case, this will be ${your_logto_endpoint}/callback/${connector_id}. e.g. https://logto.dev/callback/${connector_id}. The connector_id can be found on the top bar of the Logto Admin Console connector details page.
Click Create to finish and then you will get the Client ID and Client Secret.

Configure your connector

Fill out the clientId and clientSecret field with Client ID and Client Secret you've got from OAuth app detail pages mentioned in the previous section.

scope is a space-delimited list of scopes. If not provided, scope defaults to be openid profile email.
