AppsFlyer Native PC Unreal SDK integration

A AppsFlyer capacita os profissionais de marketing de jogos a tomar melhores decisões, fornecendo ferramentas poderosas para executar a atribuição entre plataformas.

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.

AppsflyerPCModule - Interface

AppsflyerPCModule.h, incluído na pasta appsflyer-native-pc-unreal-sample-app/AppsflyerPCModule , contém o código e a lógica necessários para se conectar aos servidores da AppsFlyer e relatar eventos.

Init

Este método recebe sua chave de API e ID do aplicativo e inicializa o módulo da AppsFlyer.

Assinatura do método

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

Arguments:

  • DEV_KEY: obtenha do profissional de marketing ou do QG da AppsFlyer.
  • APP_ID: Your Appsflyer app id (excluding the nativepc- ).

Usage:

AppsflyerPCModule()->Init(<< DEV_KEY >>, << APP_ID >>);

Start

Este método envia as primeiras solicitações de abertura/sessão para a AppsFlyer.

Assinatura do método

void Start(bool skipFirst = false)

Argumentos

  • 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
AppsflyerPCModule()->Start();

// with the flag
bool skipFirst = [SOME_CONDITION];
AppsflyerPCModule()->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.

Assinatura do método

void Stop()

Usage:

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

LogEvent

Esse método recebe um nome de evento e um objeto JSON e envia eventos in-app para a AppsFlyer.

Assinatura do método

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

Argumentos

  • std::string event_name-
  • std::string event_parameters: dictionary object which contains the predefined event parameters.
  • std::string event_custom_parameters (non-mandatory): dictionary object 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
AppsflyerPCModule()->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\":\"" + AppsflyerPCModule()->to_utf8(ws) + "\",\"goodsName2\":\"" + AppsflyerPCModule()->to_utf8(ws2) + "\"}";
// Send inapp event with custom params
AppsflyerPCModule()->LogEvent(event_name, event_parameters, event_custom_parameters);

GetAppsFlyerUID

Obter o ID do dispositivo exclusivo da AppsFlyer. O SDK gera um ID de dispositivo exclusivo da AppsFlyer na instalação do aplicativo. Quando o SDK é iniciado, esse ID é registrado como o ID da primeira instalação do aplicativo.

Assinatura do método

std::string GetAppsFlyerUID()

Usage:

AppsflyerPCModule()->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.

Assinatura do método

void SetCustomerUserId(std::string cuid)

Arguments:

  • std::string cuid: Custom user id.

Usage:

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

To_utf8

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

Assinatura do método

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\":\"" + AppsflyerPCModule()->to_utf8(ws) + "\",\"goodsName2\":\"" + AppsflyerPCModule()->to_utf8(ws2) + "\"}";

IsInstallOlderThanDate

Este método recebe uma string de data e retorna true se a data de modificação da pasta do jogo for mais antiga que a string de data. O formato da string de data é: "2023-janeiro-01 23:12:34"

Assinatura do método

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-January-23 08:30:00"

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

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

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

Executando o aplicativo de exemplo

  1. Abra o motor UE4.
  2. Escolha Novo projeto > Jogos > Primeira pessoa.
  3. Escolha C++ (em vez de Blueprints).
  4. Dê um nome ao projeto AppsFlyerSample e clique em Criar projeto.
  5. Follow the instructions to implement AppsFlyer in your game.
  6. Inicie o aplicativo de amostra do editor do mecanismo UE4.
  7. Após 24 horas, o painel é atualizado e mostra instalações orgânicas e não orgânicas e eventos in-app.

Implementing AppsFlyer in your Unreal game

Setup

  1. Abra o projeto em seu editor C++ preferido e no [YOUR-APP-NAME].Build.cs arquivo, adicione OpenSSL às suas dependências e HTTP como uma dependência privada:
PublicDependencyModuleNames.AddRange(new string[] { "Core", "CoreUObject", "Engine", "InputCore", "HeadMountedDisplay", "OpenSSL" });
PrivateDependencyModuleNames.Add("HTTP");

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

  2. Copie os seguintes arquivos de appsflyer-native-pc-unreal-sample-app/AppsflyerPCModule para a nova pasta:

    • AppsflyerPCModule.cpp
    • AppsflyerPCModule.cpp
    • AppsflyerPCModule.h
    • DeviceID.h
    • RequestData.h

  3. Gere arquivos de projeto para adicionar o OpenSSL. Saiba mais

  4. No GameMode.h arquivo, adicione o StartPlay() :

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

public:
 AAppsFlyerSampleGameMode();
 virtual void StartPlay() override;
};
  1. Abra a pasta Source/[YOUR-APP-NAME]/AppsFlyerSampleGameMode.cpp e adicione o seguinte include ao seu arquivo GameMode.cpp.
#include "AppsflyerPCModule/AppsflyerPCModule.h"
using Super = AGameModeBase;
  1. Adicione a seguinte função, certificando-se de substituir DEV_KEY and APP_ID in the init function with your app details, and report in-app events
void AAppsFlyerSampleGameMode::StartPlay()
{
   Super::StartPlay();
   // af module init
   AppsflyerPCModule()->Init(<< DevKey >>, << AppID >>);

   // af send firstopen/session
   AppsflyerPCModule()->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
   AppsflyerPCModule()->LogEvent(event_name, event_parameters);
   if (AppsflyerPCModule()->IsInstallOlderThanDate("2025-January-01 23:12:34")) {
      UE_LOG(LogTemp, Warning, TEXT("2025-January-01 23:12:34: true"));
   }
   else {
      UE_LOG(LogTemp, Warning, TEXT("2025-January-01 23:12:34: false"));
   }
   if (AppsflyerPCModule()->IsInstallOlderThanDate("2023-January-01 23:12:34")) {
      UE_LOG(LogTemp, Warning, TEXT("2023-January-01 23:12:34: true"));
   }
   else {
      UE_LOG(LogTemp, Warning, TEXT("2023-January-01 23:12:34: false"));
   }

   // 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\":\"" + AppsflyerPCModule()->to_utf8(ws) + "\",\"goodsName2\":\"" + AppsflyerPCModule()->to_utf8(ws2) + "\"}";
   // af send inapp event with custom params
   AppsflyerPCModule()->LogEvent(event_name, event_parameters, event_custom_parameters);

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