Game Center API for ID verification?

Hi. Does Game Center provide an API that could be used to verify if a TeamPlayerID is a valid one?

We are developing a game that passes the TeamPlayerID of the player (who is signed into Game Center) to its backend server in order to individualize the players.

What we would like to in the backend is to verify if the passed ID is an actual and valid TeamPlayerID. But only as the Game Center is the only one to "know" if the player ID is valid, our backend would need to verify the ID with the Game Center. The main reason for this is to prevent fake team player ID:s from being used by hackers.

Is this possible? Or is there maybe a better way to achieve similar verification?
I have a similar question as well. Hope apple dev can reply
