Having photon and node JS in Unity

We would like to have voice chat in game, so we prefer to use photon voice and photon self hosted server for handling rooms and running the authoritative game logic, all other modules in the app like authentication, wallet, IAP and socialization are planned to build using Node JS. We do need to store in-room game logs(anything happening inside the game) which should be shared to user whenever he request after the game. Is there a way to have communication between photon server and NodeJs application to validate the game moves and log them separatly. And also the amount deduction from wallet should happen in every round of game and it should be validated in the photon server. Can you let me know how does this communication will work between Photon custom server and NodeJS app.
