AppsFlyer Epic C++ SDK実装

AppsFlyerは、クロスプラットフォームアトリビューション、モバイルおよびウェブ分析、ディープリンク、不正検出、プライバシー管理と保全など、実際のペインポイントを解決する強力なツールを提供することで、ゲームマーケティング担当者がより良い意思決定を行えるように支援します。

Game attribution requires the game to communicate with AppsFlyer APIs over HTTPS and report user activities like 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 code that reports user activities in your C++.

Note: The sample code that follows is currently only supported in a Windows environment.

Prerequisites

vcpkg openssl & nlohmann-jsonパッケージ：

vcpkg install curl:x86-windows
vcpkg install nlohmann-json:x86-windows
vcpkg install openssl:x86-windows

AppsflyerLauncherModule - Interface

AppsflyerLauncherModule.h, included in the appsflyer-module folder, contains the required code and logic to connect to AppsFlyer servers and report events.

Init

このメソッドは、お客様のAPIキーとアプリIDを受け取り、AppsFlyer Moduleを初期化します。

メソッドのシグネチャ

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

例：

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

Arguments:

  • EPIC_APP_ID: Your Epic app id.
  • DEV_KEY: Get from the marketer or AppsFlyer HQ.

Start

このメソッドは、first open / session（初回起動 / セッション）リクエストをAppsFlyerに送信します。

メソッドのシグネチャ

void Start(bool skipFirst = false)

引数

  • 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

例：

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

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

メソッドのシグネチャ

void Stop()

例：

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

LogEvent

このメソッドは、イベント名とJSONオブジェクトを受け取り、アプリ内イベントをAppsFlyerに送信します。

メソッドのシグネチャ

void LogEvent(std::string event_name, json event_values, json custom_event_values = {})

引数

  • std::string event_name-
  • json event_parameters: dictionary object which contains the predefined event parameters.
  • json event_custom_parameters (non-mandatory): dictionary object which contains the any custom event parameters. For non-English values, please use UTF-8 encoding.

例：

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

// Send LogEvent request with custom event params and UTF8 encoding (for non-English characters)
std::wstring ws = L"車B1234 こんにちは";
std::wstring ws2 = L"新人邀约购物日";
json custom_event_parameters = { 
    {"goodsName", AppsflyerLauncherModule()->to_utf8(ws)}, 
    {"goodsName2", AppsflyerLauncherModule()->to_utf8(ws2)} 
};
AppsflyerLauncherModule()->LogEvent(event_name, event_parameters, custom_event_parameters);

注意：JSONを使用するためには、必ず以下のインポートを使用してください：

#include <nlohmann/json.hpp>
using json = nlohmann::json;

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.

メソッドのシグネチャ

void SetCustomerUserId(std::string cuid)

Arguments:

  • std::string cuid: Custom user id.

例：

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

SetSharingFilterForPartners

This method lets you configure which partners should the SDK exclude from data-sharing. Partners that are excluded with this method will not receive data through postbacks, APIs, raw data reports, or any other means.

メソッドのシグネチャ

void SetSharingFilterForPartners(std::string sharingFilter)

Arguments:

  • std::string sharingFilter: a list of partners to filter. For example: std::string list = "[\"partner1\",\"partner2\"]".
    Please use [\"all\"] in order to not send the event to any source.

例：

AppsflyerLauncherModule()->Init(DEV_KEY, APP_ID);

// set the sharing filter for partners a, b & c. please use ["all"] in order to not send the event to any source.
AppsflyerLauncherModule()->SetCustomerUserId("[\"a\",\"b\",\"c\"]");

// start the SDK (send firstopen/session request)
AppsflyerLauncherModule()->Start();

OnCallbackSuccess, OnCallbackFailure

上記のメソッドは、成功/失敗時に必要なアクションのプレースホルダーです。
各機能内 (“FIRST_OPEN_REQUEST”, ”SESSION_REQUEST”, ”INAPP_EVENT_REQUEST”) のコンテキストのスイッチケースで、異なる種類のイベントを処理することが可能です。

メソッドのシグネチャ

void OnCallbackSuccess(long responseCode, uint64 context)
void OnCallbackFailure(long responseCode, uint64 context)

GetAppsFlyerUID

AppsFlyerのユニークデバイスIDを取得します。SDKはアプリのインストール時にAppsFlyerのユニークなデバイスIDを生成します。SDKを起動すると、このIDが最初のアプリインストール時のIDとして記録されます。

メソッドのシグネチャ

std::string GetAppsFlyerUID()

例：

AppsflyerLauncherModule()->GetAppsFlyerUID();

To_utf8

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

メソッドのシグネチャ

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

例：

std::wstring ws = L"車B1234 こんにちは";
std::wstring ws2 = L"新人邀约购物日";
custom_event_parameters = { 
    {"goodsName", AppsflyerLauncherModule()->to_utf8(ws)}, 
    {"goodsName2", AppsflyerLauncherModule()->to_utf8(ws2)} 
};

IsInstallOlderThanDate

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

メソッドのシグネチャ

bool IsInstallOlderThanDate(std::string datestring)

Arguments:

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

例：

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

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

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

// example usage with skipFirst -
// skipping if the install date is NOT older than the given date
bool isInstallOlderThanDate = AppsflyerLauncherModule()->IsInstallOlderThanDate("2023-January-10 23:12:34");
AppsflyerLauncherModule()->Start(!isInstallOlderThanDate);
