How to send firebase auth tokens to backend server?

I want to identify currently signed-in user on my nodejs server. To do so securely, after a successful sign-in, I have to send the user's ID token to your server using HTTPS.

As in firebase docs

firebase.auth().currentUser.getIdToken(/* forceRefresh */ true).then(function(idToken) {
  // Send token to your backend via HTTPS
  // ...
}).catch(function(error) {
  // Handle error
});

If the token is sent to the backend server using AJAX post request then what should be the URL in xhr request var xhr = new XMLHttpRequest(); xhr.open('POST', url , true); and how to recieve it on nodejs backend server app.js file.

Or there is any other method to do it?

You can add an authorization header in request and parse the header value in your nodejs app. xhr.setRequestHeader('Authorization', firebaseTokenId);

In your nodejs application you can do:

 function abc(req, res) {
     authHeader = req.get('authorization');
 }
