FileMaker NFC Reader,

Greeting. I’m looking for someone is expert with FileMaker application that can work with FileMaker Cloud and FileMaker Web Direct. I will be giving tasks that it will take time from me or I can’t finish. My first Task is I have FileMaker hosted on FileMaker cloud. I’m trying to use FileMaker to capture a serial number from NFC tags (that I already pre-input the serial number on tags). I am using the Open URL call back from an app called (Simply NFC). I contact the NFC APP company and they provide me their url scheme.   ("simplynfc://reader?callback=YOUR_URI_ADDRESS”).    I managed to call back the app from FileMaker  by doing | Open URL [ with dialog off; “simplynfc://reader?callback= (here where not sure what to input) |. Right now I can call the app from FileMaker & get the Simply NFC app to read the NFC tags, however I can not manage to bring back that serial number back to FileMaker.
