Pre-Login Screen

[m1if]

I need to implement a Advisory on a screen prior to Authentication being presented. This screen would post the advisory and a click to accept button. Upon acceptance a thrid-party rest call would need to be initiated which would either return a 403 status code to terminate the attempt, or a 200 indicating that would allow EspoCRM to proceed to normal logon screen. I realize this is a special optional entry path into EspoCRM, so not looking for a feature request. But any implementation guidance or examples would be welcome.

You can define a 'login' handler. It will be processed when the login page is rendered. You can render some custom DOM from the handler.

Thank you very much. This guidance worked for me.

would you be so kind to post, how you solved it. Here are lots of not so experienced people (like me), who would appreciate an example, how to achieve something like this.
Thanks in advance.
