Get started with the PlayFab Client library for C# in Unity. Follow steps to install the package and try out example code for a basic task.

This quickstart helps you make your first PlayFab API call in the Unity engine.

Requirements

A PlayFab developer account.
An installed copy of the Unity Editor. To install Unity for personal use via Unity Hub, or Unity+ for professional use, see Download Unity.

Note

The PlayFab Unity SDK supports Unity Editor version 5.3 (released December 2015) and higher.
A Unity Project of any of the following types:
- A brand new project. For more information, see Starting Unity for the first time.
- A guided tutorial project. For more information, see Getting Started with Unity.
- An existing project.
The PlayFab Unity SDK.

Download and install PlayFab SDK

Use the PlayFab Editor Extensions package to install the SDK. The PlayFab Editor Extensions are a stand-alone Unity plug-in that streamlines installing the SDK and configuring the PlayFab settings for your Title. For information about installing the SDK without using the PlayFab Editor Extensions, see Installing the PlayFab SDK for Unity.

Download the PlayFab Unity Editor Extensions Asset Package.
Open your Unity Project.
Navigate to where you downloaded the file and double-click on the PlayFabEditorExtensions.UnityPackage file to open the Import Unity Package dialog in the Unity Editor.
To import the PlayFab Unity Editor Extensions into your project, select Import.
When the import completes, the PlayFab Unity Editor Extensions panel should open automatically. If you already created a PlayFab developer account, select the Log In link to log in with your PlayFab username and password.

Note

If the panel did not open, or if you close the panel and want to reopen it, you can do so by selecting Window > PlayFab > Editor Extensions
After logging in, the extension displays the SDK installation dialog.
Select Install PlayFab SDK to automatically import the SDK into your project or upgrade the version that is currently installed.

Set your title settings

Before you can make an API call, you must specify the Title to receive the call in the PlayFab Title Settings. To set the Title:

Select SET MY TITLE in the Editor Extensions.
Select the Studio entry to open the studio drop-down menu. Select the studio that contains the Title to which you would like to connect.
Select the Title ID entry to open a drop-down menu of Titles associated with the selected studio.

The Developer Secret Key is automatically set to the default secret key for the Title. For more information about secret keys, see Secret key management.

PlayFab Title Settings

[!NOTE] The extensions allow you to customize the http transport used to make requests to PlayFab. The recommended default is Unity Web Request. Other options exist to provide compatibility with older engine versions or game-specific http implementations.

Making your first API call

This part of the guide provides the minimum steps to make your first PlayFab API call. This example doesn't provide any GUI or on-screen feedback. Confirmation is displayed in the Console log.

If your Unity Project doesn't already have a Scripts folder (HDRP and LWRP/URP templates have one by default), right-click on the Assets folder in the Project panel and select Create > Folder.
In the Assets window, name the folder Scripts.
Right-click the Scripts folder and select Create > C# Script.
Name the script PlayFabLogin.
Double-click the file to open it in a code-editor.

In your code editor, replace the contents of PlayFabLogin.cs with the provided code and save the file.

using PlayFab;
using PlayFab.ClientModels;
using UnityEngine;

public class PlayFabLogin : MonoBehaviour
{
    public void Start()
    {
        if (string.IsNullOrEmpty(PlayFabSettings.staticSettings.TitleId)){
            /*
            Please change the titleId below to your own titleId from PlayFab Game Manager.
            If you have already set the value in the Editor Extensions, this can be skipped.
            */
            PlayFabSettings.staticSettings.TitleId = "42";
        }
        var request = new LoginWithCustomIDRequest { CustomId = "GettingStartedGuide", CreateAccount = true};
        PlayFabClientAPI.LoginWithCustomID(request, OnLoginSuccess, OnLoginFailure);
    }

    private void OnLoginSuccess(LoginResult result)
    {
        Debug.Log("Congratulations, you made your first successful API call!");
    }

    private void OnLoginFailure(PlayFabError error)
    {
        Debug.LogWarning("Something went wrong with your first API call.  :(");
        Debug.LogError("Here's some debug information:");
        Debug.LogError(error.GenerateErrorReport());
    }
}

Important

The provided code is not for use with mobile Titles. This is only an example, and shows how to log in with a CustomID. To implement login for a mobile Title, use either LoginWithAndroidDeviceID, LoginWithIOSDeviceID, or some form of social login such as LoginWithFacebook.

In the Hierarchy panel, right-click your scene, then select Create Empty (or Game Object > Create Empty in older versions of Unity).
Select the new Game Object and in the Inspector panel, select Add Component.
From the component drop-down menu, select Scripts > PlayFabLogin.

For more information on creating and using scripts in the Unity Editor, see Creating and Using Scripts in the Unity documentation.

Finish and execute

You're now ready to test out this sample.

Be sure to save all files and return to the Unity Editor
Press the Play button at the top of the editor

You should see the following message in your Unity Console Panel.

Console log of first API call

Tip

Alternatively, you can log into PlayFab and navigate to the title in Game Manager, and select the PlayStream Monitor tab. Each time you switch focus away from the actively running Unity Title, it passes an event which you can see and confirm in the PlayStream Monitor.

For a list of all available client API calls, see PlayFab API References.
