This tutorial explains how to enable a Newsletter registration form to be pre-filled from a pre-existing Login App user session.
As soon as the Login App is installed and your web pages are prepared for client-side usage of the Login App as described in Login App Setup client-side login form you can proceed to implement a Newsletter registration form.
Create Newsletter App instance
Go to Tools / Apps / Newsletter and create a new instance:
 | Enter an appropriate Title. Select English as the Used language. |
 | Remove the Category field from the Form wizard. |
 | Add least one Default list, create a List if necessary. |
 | Under Confirmation URL select Specify URL and enter the URL of the web page that will become your newsletter registration page. |
 | As usual, enter the publicly available URL of your REST Proxy. Copy the Copy template to your clipboard and paste it into your new newsletter registration page. |
Give it a try
Login to your website using the login form implemented in the previous tutorial step and navigate to the newsletter registration form.
The newsletter registration form should be pre-filled with you user’s firstname, lastname and email address.
Please note that this relies on a client-side mechanism that makes use of the global JavaScript variable window.pinuts.auth2 that is set by the file loaded via the <script> element implemented in Login App Setup client-side login form.
This mechanism for pre-filling Widget-based forms is not meant to be used to implement security-related logic!
