Install & Configure the SDK

Installing and configuring the LootLocker SDK in your Unreal project only takes a few minutes.
Install the SDK
Installing the LootLocker SDK in your project is very straightforward and flexible with different ways to set it up depending on engine version and personal preferences. Once you have downloaded the SDK, follow these steps to install the LootLocker SDK into your Unreal Engine project.
Install from Unreal Marketplace
In the Epic Games Launcher, search for LootLocker SDK, click on the LootLockerSDK and click Install to Engine.
If you were previously using the plugin as a project plugin, delete the LootLockerSDK folder under Plugins directory in your existing Unreal project.
Open your Unreal project in the Unreal Editor, navigate to Edit/Plugins in the menu and search for LootLockerSDK.
Tick Enabled, and the editor should prompt you to restart Unreal.
Once restarted, click on File->Refresh Visual Studio Project in the menu.
If you don't see "Refresh Visual Studio Project" in the File menu, click File->New C++ Class, select None, click Next, click Create Class, when compilation has finished you should see Refresh Visual Studio Project in the File menu.
Click on File->Open Visual Studio.
Once the solution opens in Visual Studio, navigate to your projects Build.cs file located in;
Games ->”ProjectName” -> Source -> “ProjectName” -> Source -> ProjectName.Build.cs
Add {“LootLockerSDK”} to the PublicDependencyModuleNames list (see example below).
PublicDependencyModuleNames.AddRange(new string[] { “Core”, “CoreUObject”, “Engine”, “InputCore”, “LootLockerSDK” });
Add {“Http”, “Json”, “JsonUtilities”} to the PrivateDependencyModuleNames list (see example below).
PrivateDependencyModuleNames.AddRange(new string[] { “Http”, “Json”, “JsonUtilities” });
Continue to the next step of the tutorial to configure the SDK in your project.
Install from Github Repository
Download or clone the repository so that you have it on disk.
Copy the LootLockerSDK folder to the Plugins folder at the root of your Unreal Project. If the Plugins folder does not exist yet, create it.
Right click the Unreal Engine Project Launch file in the root of the project and click Generate Visual Studio Project Files.
Open your project's .sln file. 
Open your project's Build.cs file and add the following.
Add {“LootLockerSDK”} to the PublicDependencyModuleNames list (see example below).
PublicDependencyModuleNames.AddRange(new string[] { “Core”, “CoreUObject”, “Engine”, “InputCore”, “LootLockerSDK” });
Add {“HTTP”, “Json”, “JsonUtilities”} to the PrivateDependencyModuleNames list (see example below).
PrivateDependencyModuleNames.AddRange(new string[] { “HTTP”, “Json”, “JsonUtilities” });
Continue to the next step of the tutorial to configure the SDK in your project.
Configure the SDK
Now that you have installed the SDK into your Unreal project, you will want to connect the Unreal project to your game in the LootLocker Web Console. The following steps walk you through configuring the LootLocker Unreal Engine SDK to work with a game that has already been created in the LootLocker Web Console. If you haven’t created a game or account yet, please visit console.lootlocker.com or follow this guide.
Configure the SDK in Project Settings
1.Login to the LootLocker Web Console by visiting console.lootlocker.com and navigate to the Settings menu and the API Keys section in order to copy the Domain and API Keys.
2.In Unreal Engine, navigate to Edit/Project Settings and scroll down the left panel until you reach the Plugins section of the Project Settings. Click on LootLockerSDK.
3.Modify the following information:
API Key is found in Game Settings in the LootLocker Web Console. Make sure to use the API key matching the environment you want to connect to. You can read more about that here. The API Key will be blurred out in the web console, so to copy it you need to press reveal <environment> key.
Domain Key is found in Game Settings in the LootLocker Web Console. 
Game Version refers to the current version of your game in the format 1.2.3.4 (the 3 and 4 being optional but recommended). LootLocker uses the SemVer standard for version numbers.
Allow Token Refresh can be selected so that the SDK automatically attempts to refresh the session token if it expires. Otherwise the session token needs to be renewed manually.
Deprecated Properties
Platform is the name of the platform the game will be built for (e.g Steam, PSN, Android, iOS). This property has been deprecated and instead of using this, you should call the StartSession method for the platform you want to use.
On Development Mode lets you test your unpublished changes in the LootLocker Management Console Stage environment (instead of Live). Checking this box will make the SDK target the Stage environment. If you want to understand this in more detail, check out the page Stage & Live Environments. This property has been deprecated, instead use the corresponding api key. Stage keys begin with dev_ and Live keys begin with prod_.
If you update the plugin in the future you might need to repeat some of these steps.
You should now have access to the SDK in both your C++ and Blueprint projects.
