AppsFlyer Meta Quest 2 Unreal SDK integration

AppsFlyer empowers gaming marketers to make better decisions by providing powerful tools to perform cross-platform attribution.

Game attribution requires the game to integrate the AppsFlyer SDK that records first opens, consecutive sessions, and in-app events. For example, purchase events.
We recommend you use this sample app as a reference for integrating the AppsFlyer SDK into your Unreal game. Note: The sample code that follows is currently only supported in a Windows environment.

Prerequisites

• Unreal Engine 4.2x.
• Follow the Quest Integration guide for Quest 2 and Unreal Engine.
• Follow the Quest 2 & Unreal 4.27 integration guide.

AppsflyerQuest2Module - Interface

AppsflyerQuest2Module.h, included in the appsflyer-meta-quest2-unreal-sample-app/Quest2_Sample/AppsflyerQuest2Module folder, contains the required code and logic to connect to AppsFlyer servers and report events.

Init

This method receives your API key and app ID and initializes the AppsFlyer Module.

Chữ ký phương thức

void Init(const char* devkey, const char* appID)

Usage:

AppsflyerQuest2Module()->Init(<< DEV_KEY >>, << QUEST_APP_ID >>);

Arguments:

• DEV_KEY: Get from the marketer or AppsFlyer HQ.
• QUEST_APP_ID: Your Quest Store app ID (For Quest 2, it's the number in the store URL - for example: https://www.oculus.com/experiences/quest/XXXXXXXXXXXXXXXX/).

Start

This method sends first open/session requests to AppsFlyer.

Chữ ký phương thức

void Start(bool skipFirst = false)

Usage:

// without the flag
AppsflyerQuest2Module()->Start();

// with the flag
bool skipFirst = [SOME_CONDITION];
AppsflyerQuest2Module()->Start(skipFirst);

LogEvent

This method receives an event name and JSON object and sends in-app events to AppsFlyer.

Chữ ký phương thức

void LogEvent(std::string event_name, json event_parameters)

Usage:

//set event name
std::string event_name = "af_purchase";
//set json string
std::string event_parameters = "{\"af_currency\":\"USD\",\"af_price\":6.66,\"af_revenue\":24.12}";
AppsflyerQuest2Module()->LogEvent(event_name, event_parameters);

GetAppsFlyerUID

Nhận ID thiết bị duy nhất của AppsFlyer. SDK sẽ tạo ra một ID thiết bị duy nhất của AppsFlyer khi cài đặt ứng dụng. Khi SDK khởi động, ID này sẽ được ghi nhận là ID của lượt cài đặt ứng dụng đầu tiên.

Chữ ký phương thức

std::string GetAppsFlyerUID()

Usage:

AppsflyerQuest2Module()->GetAppsFlyerUID();

SetCustomerUserId

Setting your own customer ID enables you to cross-reference your own unique ID with AppsFlyer’s unique ID and other devices’ IDs.
This ID is available in raw-data reports and in the Postback APIs for cross-referencing with your internal IDs.
Can be used only before calling Start().

Chữ ký phương thức

void SetCustomerUserId(std::string cuid)

Usage:

AppsflyerQuest2Module()->Init(DEV_KEY, APP_ID);
AppsflyerQuest2Module()->SetCustomerUserId("Test-18-9-23");
AppsflyerQuest2Module()->Start();

IsInstallOlderThanDate

This method receives a date string and returns true if the game folder modification date is older than the date string. The date string format is: "2023-January-01 23:12:34"

Chữ ký phương thức

bool IsInstallOlderThanDate(std::string datestring)

Usage:

// the modification date in this example is "2023-July-23 08:30:00"

// will return false
bool dateBefore = AppsflyerQuest2Module()->IsInstallOlderThanDate("2023-January-01 23:12:34");

// will return true
bool dateAfter = AppsflyerQuest2Module()->IsInstallOlderThanDate("2023-September-10 23:12:34");

// example usage with skipFirst:
bool isInstallOlderThanDate = AppsflyerLauncherModule()->IsInstallOlderThanDate("2023-April-10 23:12:34");
AppsflyerLauncherModule()->Start(isInstallOlderThanDate);

Running the sample app

1. Open the UE4 engine.
2. Choose New Project > Games > Virtual Reality.
3. Name the project Quest2_Sample and click Create project.
4. Follow the instructions to implement AppsFlyer in your game.
5. Launch the sample app from the UE4 engine editor.
6. After 24 hours, the dashboard updates and shows organic and non-organic installs and in-app events.

Implementing AppsFlyer in your Unreal game

Setup

1. Open the project in your preferred C++ editor and in the [YOUR-APP-NAME].Build.cs file, add OpenSSL to your dependencies and HTTP as a private dependency:
   (example can be found in /Quest2_Sample/Quest2_Sample.Build)

PublicDependencyModuleNames.AddRange(new string[] { "Core", "CoreUObject", "Engine", "InputCore", "HeadMountedDisplay", "OpenSSL" });
PrivateDependencyModuleNames.Add("HTTP");

2. In your Unreal Project files, under the Source/[YOUR-APP-NAME] directory, create a new directory named AppsflyerQuest2Module.

3. Copy the following files from appsflyer-meta-quest2-unreal-sample-app/AppsflyerQuest2Module to the new folder:

   • AppsflyerQuest2Module.cpp
   • AppsflyerQuest2Module.cpp
   • AppsflyerQuest2Module.h
   • DeviceID.h
   • RequestData.h

4. Generate project files in order to add OpenSSL. Learn more

5. Trong mục GameMode.h file, add the StartPlay() function:

UCLASS(minimalapi)
class AAppsFlyerSampleGameMode : public AGameModeBase
{
 GENERATED_BODY()

public:
 AAppsFlyerSampleGameMode();
 virtual void StartPlay() override;
};

6. Create a C++ Actor Component, attach it to a object of your choice, and add the following lines:
   (Alternatively you may use the example component: Quest2_Sample/Private/AF_ActorComponent.cpp)

#include "../AppsflyerQuest2Module/AppsflyerQuest2Module.h"

7. Add the following function, making sure to replace DEV_KEY and QUEST_APP_ID in the init function with your app details, and report in-app events

void UAF_ActorComponent::BeginPlay()
{
	Super::BeginPlay();
	AppsflyerQuest2Module()->Init(<< DEV_KEY >>, << QUEST_APP_ID >>);
	// af send firstopen/session
	AppsflyerQuest2Module()->Start();
	//set event name
	std::string event_name = "af_purchase";
	//set json string
	std::string event_parameters = "{\"af_currency\":\"USD\",\"af_price\":6.66,\"af_revenue\":24.12}";
	// af send inapp event
	AppsflyerQuest2Module()->LogEvent(event_name, event_parameters);
	// ...	
}

Resetting the attribtion

Delete the APK from your Oculus Device and then Re-deploy (a new AppsFlyerUID will be created).
