# Unity SDK Overview

> Integrate PlayFlow multiplayer services directly into your Unity projects with our native SDK.

The PlayFlow Unity SDK provides a powerful and convenient way to manage your game servers, lobbies, and matchmaking directly within the Unity Editor and your game's C# scripts.

<Info>
  **Prerequisites**

  * A PlayFlow account with a project (new organizations start on the **Free** plan).
  * A project **API key**. You can create both server keys (`pf_...`) and client keys (`pfclient_...`) from the **API Keys** section of your project.
  * Unity 2021.3 LTS or newer.
</Info>

## Key Features

* **In-Editor Management**: A user-friendly editor window to manage your PlayFlow account, server builds, and deployments without leaving Unity.
* **C# API Clients**: High-level C# APIs for interacting with PlayFlow's services, including Game Servers, Lobbies, and Matchmaking.
* **Simplified Workflow**: Designed to streamline the development process for multiplayer games, from prototyping to production.
* **Example Scenes**: Comes with clear examples to help you get started quickly.

## Installation

## Initial Setup

Once imported, the SDK needs to be configured with your PlayFlow API Key.

1. Find the `PlayFlowLobbyManagerV2` component in your scene, or add it to a new GameObject.
2. In the Inspector for `PlayFlowLobbyManagerV2`, enter your **API Key**. You can find this in the **API Keys** section of your PlayFlow project.
3. That's it! The manager will now be able to authenticate with PlayFlow services.

<Warning>
  Because the SDK ships inside your game client, use a **client key** (`pfclient_...`), which is safe to distribute in game builds. Keep **server keys** (`pf_...`) server-side only — they have full access and can delete builds and change project settings.
