Set up OAuth client on Google Cloud Platform

To configure Google OAuth client for Authgear, you will need to create an OAuth client on Google Cloud Platform first.

Create a new project

Create a project on Google Cloud Platform through console. If you are adding Authgear to your existing Google Cloud Platform projects, you may skip to the next step to create the OAuth client.
After creating a new project, you will need to configure the OAuth consent screen. Press the
button on the top-left and go to APIs & Services -> OAuth consent screen and follow the instruction to create the consent screen.

Create OAuth client ID

  1. 1.
    Go to
    -> APIs & services -> Credentials

    Choose Web application in Application type and assign a name as reference. You should always choose Web application here regardless of the platform of the app you are creating. It is because this OAuth Client ID is used by your Authgear services, which is a web application in Google’s classification.
  4. 4.
    Add https://<YOUR_AUTHGEAR_ENDPOINT>/sso/oauth2/callback/google to redirect URIs.
  5. 5.
    After creating a client ID, you will see the client ID under the OAuth 2.0 Client IDs section of the Credentials page.

Redirect URI has the form of /sso/oauth2/callback/:alias. The alias is used as the identifier of OAuth provider. You can configure the alias in Authgear Portal.
