Google Sign-In manages the OAuth 2.0 flow and token lifecycle, simplifying your integration with Google APIs. A user always has the option to revoke access to an application at any time.
Before you can integrate Google 3P Authorization library into your website, you must create a client ID, which you need to call the 3P Authorization API.
When you configure the project, select the Web browser client type and specify the origin URI of your app. When you perform tests, both http://localhost and http://localhost:<port_number> must be added to the Authorized JavaScript origins field.
After configuration is complete, take note of the client ID that was created. You will need the client ID to complete the next steps. (A client secret is also created, but you need it only for server-side operations.)
