Signs the user in using an iOS Game Center player identifier, returning a session identifier that can subsequently be used for API calls which require an authenticated user

Request Details

The Game Center player identifier ( is a generated string which is stored on the local device. As with device identifiers, care must be taken to never expose a player's Game Center identifier to end users, as that could result in a user's account being compromised. If this is the first time a user has signed in with Game Center and CreateAccount is set to true, a new PlayFab account will be created and linked to the Game Center identifier. In this case, no email or username will be associated with the PlayFab account. Otherwise, if no PlayFab account is linked to the Game Center account, an error indicating this will be returned, so that the title can guide the user through creation of a PlayFab account.
