Missing OAuth2 Callback URL for Google Credentials on n8n.cloud

When using n8n.cloud, the Google OAuth credentials are handled in a managed way. This means you don’t see or need to manually configure the OAuth2 callback URL as you would with a self-hosted instance. When you click “Sign in with Google” on n8n.cloud, the underlying infrastructure takes care of the OAuth flow and the callback URL internally, so it isn’t displayed to you.

If you need to set up Google API credentials manually (for example, in a self-hosted instance), you would get the OAuth Redirect URL from your n8n credential’s details and paste it into the Authorized redirect URIs in the Google Cloud Console. On n8n.cloud, since the OAuth handling is built-in and managed, you don’t have to worry about this step.

In summary, on n8n.cloud you simply use the “Sign in with Google” option, and the OAuth callback is automatically managed by the platform. If your use case requires manually specifying or copying the callback URL, you’d need to deploy a self-hosted instance where that information is exposed in the credential configuration.
