I have a splash page to show users before they connect to my wifi. I want them to take a little survey before granting access, the survey is on a third party server (questionpro.com) and loads on my page by an iframe.
The problem is that I have no way to know if the user actually answered, because it all happens inside the iframe, I can't interact with the iframe because same-origin policy, I tried to use iframeTracker to detect when the user clicks the iframe, but I don't think this is ideal.
I realized the only thing that changes is the number of request on my developer tools, so, is there a way to keep track of these ones? If not, do you have any idea to make it work?
