Exchange a Google ID token (obtained via the native/mobile SDK) for Auth0 accessToken, idToken, and refreshToken. The backend also syncs the user record into MongoDB on first login.

​
Testing with the Token Generator Tool

We provide a simple HTML tool to generate Google ID tokens for testing your API locally.

​
Prerequisites

  • A Google OAuth Client ID from Google Cloud Console
  • Make sure http://localhost:3000 is added to the Authorized JavaScript origins in your OAuth client configuration

​
Running the Token Generator

1

Start the local server

From the project root, run:
npx serve -l 3000
This starts a static file server on http://localhost:3000.
2

Open the token generator

Navigate to http://localhost:3000/test-google-token.html in your browser.
3

Enter your Client ID

Paste your Google OAuth Client ID into the input field and press Enter or click the “Sign in with Google” button.
4

Sign in with Google

Complete the Google sign-in flow. Once authenticated, your ID token will be displayed.
5

Use the token

Copy the token and use it to test the /api/v1/auth/google endpoint:
curl -X POST http://localhost:8080/api/v1/auth/google \
  -H "Content-Type: application/json" \
  -d '{"idToken": "YOUR_COPIED_TOKEN"}'
