Abort check-in for a tournament

Deprecated

POST

/tournaments/{tournament}/abort_check_in.json

When your tournament is in a 'checking_in' or 'checked_in' state, there's no way to edit the tournament's start time (start_at) or check-in duration (check_in_duration). You must first abort check-in, then you may edit those attributes.

Makes all participants active and clears their checked_in_at times.
Transitions the tournament state from 'checking_in' or 'checked_in' to 'pending'
