# Rollback the ticket

The request is used in case Bet Engine made a ticket’s rollback. 

Rollback happens when the ticket is originally set one way, but later (can be minutes or sometimes even days after) the results are changed and the ticket is set differently. A ticket’s rollback means that ticket status changes to the previous ticket status (open) and then it can be set to the opposite. After successful response Bet Engine should make a `ticket_win` / `ticket_lost` / `ticket_void` request.

Request fields:
