I'm using fackbook JS API in order to get the user's friends. The user choose one of his friends in a website and send him a greeting. The server gets a source facebook ID of the user and a destination facebook ID (from his friends list)
how can I be sure that the user didn't "touch" the source user and destination user facebook ID ?
I want to save it in my database. is there any solution for that?
