API Reference (API Version 2015-10-01)

AcceptMatch

Registers a player's acceptance or rejection of a proposed FlexMatch match. A matchmaking configuration may require player acceptance; if so, then matches built with that configuration cannot be completed unless all players accept the proposed match within a specified time limit.

When FlexMatch builds a match, all the matchmaking tickets involved in the proposed match are placed into status REQUIRES_ACCEPTANCE. This is a trigger for your game to get acceptance from all players in the ticket. Acceptances are only valid for tickets when they are in this status; all other acceptances result in an error.

To register acceptance, specify the ticket ID, a response, and one or more players. Once all players have registered acceptance, the matchmaking tickets advance to status PLACING, where a new game session is created for the match.

If any player rejects the match, or if acceptances are not received before a specified timeout, the proposed match is dropped. The matchmaking tickets are then handled in one of two ways: For tickets where all players accepted the match, the ticket status is returned to SEARCHING to find a new match. For tickets where one or more players failed to accept the match, the ticket status is set to FAILED, and processing is terminated. A new matchmaking request for these players can be submitted as needed.
