Can you put a form action tag in SharePoint online page to post to aspx file that is on prem? Or maybe would be better to re-do the target application in PowerApps instead -

Hi @Richard Lukasik ,

According to my research and testing, unfortunately, there is currently no way to put a form action tag in SharePoint online page to post to the .aspx file on prem. Thanks for your understanding.

Answer 2

you can do this with a Sharepoint add-in:

Sharepoint add-ins are written in javascript. the add-in would would just render a form with the desired action. you could use ajax to do the post.
