## Return Value

The resulting ticket object.

## Remarks

The library automatically, and asynchronously, will submit a server backfill ticket to the matchmaking service. Each time the ticket status changes, a [`OnMatchmakingTicketStatusChanged`](/services/playfab/multiplayer/lobby/unity-multiplayer-api-reference/PlayFab.Multiplayer/PlayFabMultiplayer/OnMatchmakingTicketStatusChanged) will be provided. The ticket status can be queried at any time via [`Status`](/services/playfab/multiplayer/lobby/unity-multiplayer-api-reference/PlayFab.Multiplayer/MatchmakingTicket/Status). The ticket immediately starts in the `MatchmakingTicketStatus.Creating` state.

When the ticket has completed, a [`OnMatchmakingTicketStatusChanged`](/services/playfab/multiplayer/lobby/unity-multiplayer-api-reference/PlayFab.Multiplayer/PlayFabMultiplayer/OnMatchmakingTicketStatusChanged) will be provided. At that point, a match for the backfill ticket will have been found or the ticket stopped due to failure. On success, the match that was found can be queried via [`GetMatchDetails`](/services/playfab/multiplayer/lobby/unity-multiplayer-api-reference/PlayFab.Multiplayer/MatchmakingTicket/GetMatchDetails). The `regionPreferences` in regionPreferences will only contain the region that the server is located in.

This function requires that a previous call to [`SetEntityToken`](/services/playfab/multiplayer/lobby/unity-multiplayer-api-reference/PlayFab.Multiplayer/PlayFabMultiplayer/SetEntityToken) was made to set the game server entity token.

While this method is present in the unified, cross-platform header, it is only implemented for Windows and, XBOX. The method will return errors on other platforms.
