AppsFlyer Meta Quest 2 Unreal SDK integration

Integrate your Meta Quest Unreal app or game with AppsFlyer to measure the performance of campaigns marketing these apps.

Game attribution and user measurement require the game to integrate an AppsFlyer SDK that records first opens, sessions, and in-app events. For example, purchase events.

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 в папке appsflyer-meta-quest2-unreal-sample-app/Quest2_Sample/AppsflyerQuest2Module содержит необходимый код и логику для подключения к серверам AppsFlyer и передачи отчетов по событиям.

Init

Данный метод содержит ваш ключ API и идентификатор приложения и инициализирует модуль AppsFlyer.

Сигнатура метода

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

Usage:

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

Arguments:

• DEV_KEY: получите у маркетолога или 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

Данный метод передает запросы «first open/session» в AppsFlyer.

Сигнатура метода

void Start(bool skipFirst = false)

Аргументы

• bool skipFirst: Determines whether or not to skip first open events and send session events. The value is false by default. If true , first open events are skipped and session events are sent. See example

Usage:

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

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

Stop

This method stops the SDK from functioning and communicating with AppsFlyer servers. It's used when implementing user opt-in/opt-out.

Сигнатура метода

void Stop()

Usage:

// Starting the SDK
AppsflyerQuest2Module()->Start();
// ...
// Stopping the SDK, preventing further communication with AppsFlyer
AppsflyerQuest2Module()->Stop();

LogEvent

Этот метод получает имя события и объект JSON и отправляет внутренние события приложения в AppsFlyer.

Сигнатура метода

void LogEvent(std::string event_name, std::string event_values, std::string custom_event_values = "")

Аргументы

• std::string event_name: The name of the event.
• std::string event_parameters: String which contains the predefined event parameters.
• std::string event_custom_parameters [Optional]: String which contains the any custom event parameters. For non-English values, please use UTF-8 encoding.

Usage:

// Setting the event parameters json string and event name
std::string event_name = "af_purchase";
std::string event_parameters = "{\"af_currency\":\"USD\",\"af_revenue\":24.12}";
// Send the InApp event request
AppsflyerQuest2Module()->LogEvent(event_name, event_parameters);

// Set non-English values for testing UTF-8 support
std::wstring ws = L"車B1234 こんにちは";
std::wstring ws2 = L"新人邀约购物日";
std::string event_custom_parameters = "{\"goodsName\":\"" + AppsflyerQuest2Module()->to_utf8(ws) + "\",\"goodsName2\":\"" + AppsflyerQuest2Module()->to_utf8(ws2) + "\"}";
// Send inapp event with custom params
AppsflyerQuest2Module()->LogEvent(event_name, event_parameters, event_custom_parameters);

GetAppsFlyerUID

Get the AppsFlyer unique device ID. The SDK generates an AppsFlyer unique device ID upon app installation. When the SDK is started, this ID is recorded as the ID of the first app install.

Сигнатура метода

std::string GetAppsFlyerUID()

Usage:

AppsflyerQuest2Module()->GetAppsFlyerUID();

SetCustomerUserId

This method sets a customer ID that enables you to cross-reference your unique ID with the AppsFlyer unique ID and other device IDs. Note: You can only use this method before calling Start().
The customer ID is available in raw data reports and in the postbacks sent via API.

Сигнатура метода

void SetCustomerUserId(std::string cuid)

Arguments:

• std::string cuid: Custom user id.

Usage:

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

To_utf8

This method receives a reference of a std::wstring and returns UTF-8 encoded std::string

Сигнатура метода

std::string to_utf8(std::wstring& wide_string);

Usage:

// Set non-English values for testing UTF-8 support
std::wstring ws = L"車B1234 こんにちは";
std::wstring ws2 = L"新人邀约购物日";
std::string event_custom_parameters = "{\"goodsName\":\"" + AppsflyerQuest2Module()->to_utf8(ws) + "\",\"goodsName2\":\"" + AppsflyerQuest2Module()->to_utf8(ws2) + "\"}";

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".

Сигнатура метода

bool IsInstallOlderThanDate(std::string datestring)

Arguments:

• std::string datestring: Date string in yyyy-mm-ddThh:mm:ss+hh:mm format.

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);

Запуск примера приложения

1. Откройте UE4 Engine.
2. Choose New Project > Games > Virtual Reality.
3. Дайте проекту имя Quest2_Sample и нажмите Create project (Создать проект).
4. Follow the instructions to implement AppsFlyer in your game.
5. Запустите пример приложения из редактора UE4 Engine.
6. Через 24 часа дэшборд обновляется и отображает органические и неорганические установки и внутренние события приложения.

Implementing AppsFlyer in your Unreal game

Setup

1. Откройте проект в предпочтительном редакторе C++, затем в файле [YOUR-APP-NAME].Build.cs добавьте OpenSSL в свои зависимости и 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. Скопируйте следующие файлы из appsflyer-meta-quest2-unreal-sample-app/AppsflyerQuest2Module в новую папку:

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

4. Сгенерируйте файлы проекта и добавьте OpenSSL. Узнать больше

5. В GameMode.h добавьте StartPlay() :

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. Добавьте следующую функцию, заменив 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();
	// af module init
	AppsflyerQuest2Module()->Init(<< DEV_KEY >> , << PACKAGE_NAME >> );


	// 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_revenue\":24.12}";
	// af send inapp event
	AppsflyerQuest2Module()->LogEvent(event_name, event_parameters);

	// set non-English values for testing UTF-8 support
	std::wstring ws = L"車B1234 こんにちは";
	std::wstring ws2 = L"新人邀约购物日";
	std::string event_custom_parameters = "{\"goodsName\":\"" + AppsflyerQuest2Module()->to_utf8(ws) + "\",\"goodsName2\":\"" + AppsflyerQuest2Module()->to_utf8(ws2) + "\"}";
	// af send inapp event with custom params
	AppsflyerQuest2Module()->LogEvent(event_name, event_parameters, event_custom_parameters);

	// stop the SDK
	AppsflyerQuest2Module()->Stop();
}

Resetting the attribtion

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