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.
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.

​
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

To get started with the PlayFlow Unity SDK, please follow our complete installation guide.

Installation Guide

Follow the steps to install the SDK using the Unity Package Manager.

​
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.
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.

Game Servers
