Handle Auth0 User Login Events via Webhook

## 1. First, go to {{ $env.WEBHOOK_URL }} and create a Single Page Application. From Dashboard/Applications, click on your new app settings. The first step is to add the following to allowed callback URLs:
{{ $env.WEBHOOK_URL }} {{ $env.WEBHOOK_URL }} 

### (If you do not run n8n locally, replace localhost with your server where you run n8n. You must also replace it in **Set Application Details** 'my_server' field)

## From the same settings page,  retrieve the Domain, Client_ID, and Client_Secret of your application.
