We have a client with a Mikrotik Hotspot onsite and a remote Mikrotik User Manager that authenticates users.
What they want is a 30 minute voucher, that if expired, brings a pop up/ or redirects their browser - this takes them to a survey. If the user completes the survey they have their time extended by another 30minutes (or possibly issue them with new login details with 30 minutes available), however this pop-up or redirected page must only be available once per voucher. (and not available to the vouchers generated after the survey – if that route is taken).
If someone has done something similar or is willing to do the programming I am willing to pay for the customization.
Please email me if you are willing to take something like this on.
