# Submit or update player stats for a map

`POST /game/matches/{matchId}/player-stats`

Sets per-player stats on an existing map score for the given mapIndex. Requires the game.scores:write permission. Supports an optional `Idempotency-Key` request header: a retry with the same key and body replays the original response, while the same key with a different body returns 409 error_idempotency_key_conflict. The idempotency identity is scoped per match.

  - `mapIndex` integer, required — Zero-based index of the map whose stats are being updated.
  - `playerStats` object, required — Per-player stats keyed by user ID. The map score must already exist.

## Response `200`

The player stats were updated.

- GamePlayerStatsResponse — Result of a successful player-stats update.
  - `success` true, required
  - `mapIndex` integer, required — Index of the map whose stats were updated.
  - `action` string, required — Operation performed, always "updated" on success.
