Using one of the Google API Client Libraries (e.g. Java, Node.js, PHP, Python) is the recommended way to validate Google ID tokens in a production environment.

npm install google-auth-library --save

Node.js

const { OAuth2Client } = require('google-auth-library');
const client = new OAuth2Client(CLIENT_ID);
async function verify() {
	const ticket = await client.verifyIdToken({
		idToken: token,
		audience: CLIENT_ID, // Specify the CLIENT_ID of the app that accesses the backend
		// Or, if multiple clients access the backend:
		//[CLIENT_ID_1, CLIENT_ID_2, CLIENT_ID_3]
	});
	const payload = ticket.getPayload();
	const userid = payload['sub'];
	// If request specified a G Suite domain:
	// const domain = payload['hd'];
}
verify().catch(console.error);
