In APIs & Services, go to Credentials on the left sidebar.
Click the Create credentials dropdown button and select OAuth client ID.
Select Web application as the Application type.
Fill in all required fields, such as the Name of the client.
Add your Authorized JavaScript origins (your web app’s domain) and Authorized redirect URIs (where users will be redirected to after successful authentication).
Click Create to generate the client credentials. Save the Client ID and Client Secret as you’ll need these in your frontend and backend configurations.
Follow the steps below to configure the login in the Publisher Dashboard:
Go to Settings -> Authentication.
Toggle on Google App, and enter your Google ID in the Google App ID field.
The button for logging in with Google will appear in the web store login page.
Once a player selects this method, Google generates a token. Apppcharge sends this token along with other login information to your Authenticate Player API for verification.
Once verified, the player is logged into the web store.
