How to retrieve event.response?

[robertbrower-technologies]

I have a onPostAuthentication lambda function set up and being called on my user pool's post authentication trigger. In this function I set event.response.accessToken = accessToken;

How can I retrieve this token in my Angular 2 single page app when a user logs in?

Thank you!

Take a look at the CognitoUtil.getAccessToken function.

My question was more related to how to pass things back in event.response of a lambda to the caller via the callback method and retrieve them in the webapp via the api.
