# Players & arenas API

Match Play APIs will generally only respond with the player id or the arena id for performance reasons. Separate API requests are necessary to receive the underlying player and arena objects.

When [fetching a tournament](/tournaments-api.md#get-tournament) set `includePlayers=true` and `includeArenas=true` to receive the initial set of players and arenas for the tournament. If you subsequently are exposed to unknown player or arena ids you can use the APIs on this page to resolve them.

## Resolve unknown arenas

```http
GET /api/arenas/resolve-unknown
```

Provide a comma-separated list of arena ids and receive the arena objects.

| ----------------- | ----------------------------------------------------------------- |
| `arenas` (string) | Comma-separated list of arena ids. Provide no more than `25` ids. |
