AppsFlyer Native PC C++ SDK integration
AppsFlyer empowers gaming marketers to make better decisions by providing powerful tools that solve real pain points, including cross-platform attribution, mobile and web analytics, deep linking, fraud detection, privacy management and preservation, and more.
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 packages:
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
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:
AppsflyerLauncherModule()->Init(<< DEV_KEY >>, << APP_ID >>);
Arguments:
APP_ID
: Your app id (excluding thenativepc-
tiền tố).DEV_KEY
: Get from the marketer or AppsFlyer HQ.
Start
This method sends first open/session requests to AppsFlyer.
Chữ ký phương thức
void Start(bool skipFirst = false)
Đối số
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
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.
Chữ ký phương thức
void Stop()
Usage:
// Starting the SDK
AppsflyerLauncherModule()->Start();
// ...
// Stopping the SDK, preventing further communication with AppsFlyer
AppsflyerLauncherModule()->Stop();
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_values, json custom_event_values = {})
Đối số
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.
Usage:
// 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);
Note: To use the JSON, make sure to use the following imports:
#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.
Chữ ký phương thức
void SetCustomerUserId(std::string cuid)
Arguments:
std::string cuid
: Custom user id.
Usage:
AppsflyerLauncherModule()->Init(DEV_KEY, APP_ID);
AppsflyerLauncherModule()->SetCustomerUserId("Test-18-9-23");
AppsflyerLauncherModule()->Start();
OnCallbackSuccess, OnCallbackFailure
The above methods are placeholders for the desired actions upon success/failure.
It is possible to handle different types of events with the switch case of the context within each function (“FIRST_OPEN_REQUEST”, ”SESSION_REQUEST”, ”INAPP_EVENT_REQUEST”).
Chữ ký phương thức
void OnCallbackSuccess(long responseCode, uint64 context)
void OnCallbackFailure(long responseCode, uint64 context)
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:
AppsflyerLauncherModule()->GetAppsFlyerUID();
To_utf8
This method receives a reference of a std::wstring
and returns UTF-8 encoded std::string
Chữ ký phương thức
std::string to_utf8(std::wstring& wide_string);
Usage:
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"
Chữ ký phương thức
bool IsInstallOlderThanDate(std::string datestring)
Arguments:
std::string datestring
: Date string inyyyy-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 = 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);
Running the sample app
- Install Visual Studio.
- Open the solution.
- Open the
AppsflyerSampleApp.cpp
file. - On line 110, replace
DEV_KEY
andAPP_ID
with your app details. - Run the app by clicking Play on the top toolbar (Local Windows Debugger). Make sure that the mode is set to Debug.
- After 24 hours, the dashboard updates and shows organic and non-organic installs and in-app events.
Implementing AppsFlyer in your C++ app
Setup
- Copy the files from the

folder into your C++ project under Header Files > AppsFlyer. - Import the Module:
#include "AppsflyerLauncherModule.h"
- Nhập
nlohmann-json
:
#include <nlohmann/json.hpp>
using json = nlohmann::json;
- Initialize and start the AppsFlyer integration.
- Report in-app events.
