You can use the Google Authentication Management to create and manage configurations for Google projects.

You can configure the Client Id and Client Secret for a Google project. Add the scopes you need for your integration and associate this configuration to the OutSystems modules where you're going to use them. This way, when using those modules, you don't need to specify scopes or project information when implementing the google login. Usually, the APIs that you are going to use refer the needed scopes. 

Scopes are permissions that you might need to request to access Google APIs, depending on the level of access you need.

It serves has a unique place to manage all your google projects configurations for your environment. 

This component will install the Google Authentication Core component and it should be used after the Google Authentication Core configuration.
