Multiplayer API

Multiplayer Games Support

Start Multiplayer Tournament:

  1. We need to start the tournament by calling the start tournament API with each and every individual who participates in the multiplier tournament

  2. The backend will validate the player’s identity, tournament pass, number of attempts left, etc.. before letting them join the tournament.

End Multiplier Tournament With Score Posting:

  1. The multiplayer tournament can be ended with a single API call that sends all the players-score along with the rank.

  2. These scores will be validated and the score posting will happen on the tournament leaderboard, guild leaderboard, and persistent leaderboard based on the game
