I have an web application which allows login to the WiFi network after authorization. The application uses a platform Pimpcore. You can login to the WiFi network after the acceptation of the Rules, passed email address, or log in to social media for example: Instagram, Twitter, Google+, or Facebook. Additionaly, the application collects information about users. In August 2016 years, Facebook has disabled REST API, which the application used. I'm looking for person who could change the old Facebook REST API to new Facebook GRAPH API, enabling login to the Wifi network using this portal.
