# Integrations with other UGS services

> Connect Matchmaker with Leaderboards and Game Overrides to enhance your matching capabilities.

Matchmaker integrates with different UGS services, including [Leaderboard](/leaderboards.md) and [Game Overrides](/game-overrides.md) to provide a complete suite of features.

## Server Authoritative Data

Matchmaker integrates with [Leaderboard](/leaderboards.md) to enable you to attach a score, a rank, and a tier to a player. Leaderboard seamlessly integrates this data into a matchmaking ticket and creates [matchmaking rules](./mm-rules.md#leaderboards) based on the data.

## Game Overrides

Matchmaker integrates with [Game Overrides](/game-overrides.md) to enable [A/B testing](./ab-testing.md) of matchmaking configurations. To learn more, refer to [A/B testing](/game-overrides/ab-testing.md).

## Cloud Save

Use [Cloud Save](/cloud-save.md) as a data source for Matchmaker rules. Refer to [Rules](./mm-rules.md) for an example.
