Mikrotik Facebook social media login/checkin for hotspot

Hi I want my clients to login via a Facebook/social media login through our Mikrotik router. To give customers free wifi, however they have to use facebook like or checkin to be able to use wifi. [login to view URL] - I have used the routers Facebook recommends but want to use a Mikrotik device. I'd like to keep config on the Mikrotik router, i don't want to use an external server. If you have already designed something for someone else and is working - please contact me, i'd like to use what you have.
