Want To Post From A Apps Script Form To Another App Script

I have an addon shared to all domain-users. It opens a sidebar that contains a form. I want the form to post to another Apps Script (implemented webapp) in a basic client-server fa

Solution 1:

It works with no security (anyone can access, even anonymously) on the webapp. Otherwise it will force a Google Signin.

sidebar.html (from client-script.gs)

<form id="myForm" target="_self" method="post" action="https://script.google.com/macros/s/SCRIPT_ID/exec">
  <input name="name"type="text" value=""/>   
  <input name="message"type="text" value=""/>
  <inputtype="submit" value="send" />
</form>
