I’m trying to implement a single page application and an API

My single page application has google as an authentication method.

My frontend makes a request to [https://blah.eu.auth0.com/oauth/token](https://blah.eu.auth0.com/oauth/token) and gives me back

an access\_token which is a 32 char token and an id\_token which seems to be a jwt token that contains my google information.

Which of these should I send to my backend. Should I send the access token and then use that to get the user id? Or the jwt token and decode it to get the userId

Hi @patrickcorrigan7,

If you are looking to send your backend API an access token you should register it and add the identifier as the token audience. Here is an FAQ about it:
