This Module is Built for

• StoreKit SDK v1.
• iOS version 9 and higher.
• iOS AppsFlyer SDK 6.8.0 and higher.

*IMPORTNANT NOTE: Please, be sure to check Purchase Connector and AppsFlyerFramework version compatability table and use corresponding versions to avoid unexpected behaviour *

PurchaseConnector	AppsFlyerSDK
6.8.0	6.8.0 - 6.9.2
6.8.1	6.8.0 - 6.9.2
6.10.0	6.10.0
6.10.1	6.10.1
6.12.2	6.12.2
6.12.3	6.12.2

Adding The Connector To Your Project via Cocoapods:

Add to your Podfile and run pod install:

// for statically linked dependency
pod 'PurchaseConnector'

// for dynamically linked dependency
pod 'PurchaseConnector/Dynamic'

// for statically linked Strict dependency (disabled IDFA collection)
pod 'PurchaseConnector/Strict'

Adding The Connector To Your Project via Carthage:

Go to the Carthage folder in the root of the repository. Open purchase-connector-dynamic.json or purchase-connector-static.json, click raw, copy and paste the URL of the file to your Cartfile:

binary "https://raw.githubusercontent.com/AppsFlyerSDK/appsflyer-apple-purchase-connector/main/Carthage/purchase-connector-dynamic.json" == BIINARY_VERSION
binary "https://raw.githubusercontent.com/AppsFlyerSDK/AppsFlyerFramework/master/Carthage/appsflyer-ios.json" ~> 6.10.0

Then open project folder in the terminal and use command carthage update --use-xcframeworks, then, drag and drop PurchaseConnector.xcframework binary and AppsFlyerLib.framework (from Carthage/Build/iOS folder).

More reference on Carthage binary artifacts integration here.

Adding The Connector To Your Project via SPM:

Please, follow standard SPM dependency manager instructions.

Note: This repository contains statically linked PurchaseConnector.xcframework. If you want to use dynamic .xcframework, please integrate it for SPM from this repository: https://github.com/AppsFlyerSDK/PurchaseConnector-Dynamic

Note: as PurchaseConnector has a dependency on AppsFlyerLib framework, please, make sure to integrate it as well for Carthage and SPM.

Basic Integration Of The Connector

Note: before the implementation of the Purchase connector, please make sure to set up AppsFlyer appId and devKey

Set up Purchase Connector

• Swift

// Import the library
    import AppsFlyerLib
    import StoreKit
    import PurchaseConnector

// Default SDK Implementation
    AppsFlyerLib.shared().appsFlyerDevKey = "DEV_KEY"
    AppsFlyerLib.shared().appleAppID = "APPLE_APP_ID"
    //AppsFlyerLib.shared().isDebug = true

// Purchase connector implementation 
    PurchaseConnector.shared().purchaseRevenueDelegate = self
    PurchaseConnector.shared().purchaseRevenueDataSource = self

• Objective-C

// Import the library
    #import "AppDelegate.h"
    #import <AppsFlyerLib/AppsFLyerLib.h>
    #import <PurchaseConnector/PurchaseConnector.h>

// Default SDK implementation
    [[AppsFlyerLib shared] setAppleAppID:@"APPLE_APP_ID"];
    [[AppsFlyerLib shared] setAppsFlyerDevKey:@"DEV_KEY"];
    //[[AppsFlyerLib shared] setIsDebug:YES];

// Purchase Connecor implementation
    [[PurchaseConnector shared] setPurchaseRevenueDelegate:self];
    [[PurchaseConnector shared] setPurchaseRevenueDataSource:self];

Log Auto-Renewable Subscriptions and In-App Purchases

Enables automatic logging of In-App purchases and Auto-renewable subscriptions.

• Swift

PurchaseConnector.shared().autoLogPurchaseRevenue = [.autoRenewableSubscriptions, .inAppPurchases]

• Objective-C

[[PurchaseConnector shared] setAutoLogPurchaseRevenue:AFSDKAutoLogPurchaseRevenueOptionsRenewable | AFSDKAutoLogPurchaseRevenueOptionsInAppPurchases];

Note: if autoLogPurchaseRevenue has not been set, it is disabled by default. The value is an option set, so you can choose what kind of user purchases you want to observe.

Conform to Purchase Connector Data Source and Delegate protocols

• In order to receive purchase validation event callbacks, you should conform to and implement PurchaseRevenueDelegate(Swift) or AppsFlyerPurchaseRevenueDelegate(Objc-C) protocol.
• To be able to add your custom parameters to the purchase event, that Connector sends, please conform to and implement PurchaseRevenueDataSource(Swift) or AppsFlyerPurchaseRevenueDataSource(Obj-C) protocol.

• Swift

extension AppDelegate: PurchaseRevenueDataSource, PurchaseRevenueDelegate {
    // PurchaseRevenueDelegate method implementation
    func didReceivePurchaseRevenueValidationInfo(_ validationInfo: [AnyHashable : Any]?, error: Error?) {
        print("PurchaseRevenueDelegate: \(validationInfo)")
        print("PurchaseRevenueDelegate: \(error)")
      // process validationInfo here 
}
    // PurchaseRevenueDataSource method implementation
    func purchaseRevenueAdditionalParameters(for products: Set<SKProduct>, transactions: Set<SKPaymentTransaction>?) -> [AnyHashable : Any]? {
        // Add additional parameters for SKTransactions here.
        return ["additionalParameters":["param1":"value1", "param2":"value2"]];
    }
}

• Objective-C

@interface AppDelegate () <AppsFlyerPurchaseRevenueDelegate, AppsFlyerPurchaseRevenueDataSource>
@end

@implementation AppDelegate

- (void)applicationDidBecomeActive:(UIApplication *)application {
    [[AppsFlyerLib shared] start];
    [[PurchaseConnector shared] startObservingTransactions];
}

- (void)didReceivePurchaseRevenueValidationInfo:(NSDictionary *)validationInfo error:(NSError *)error {
    NSLog(@"Validation info: %@", validationInfo);
    NSLog(@"Error: %@", error);
    
    // Process validation info
}

- (NSDictionary *)purchaseRevenueAdditionalParametersForProducts:(NSSet<SKProduct *> *)products transactions:(NSSet<SKPaymentTransaction *> *)transactions {
    return @{@"key1" : @"param1"};
}

@end

Start Observing Transactions

startObservingTransactions should be called to start observing transactions.

Note: This should be called right after the AppsFlyer iOS SDK's start method..

• Swift

    PurchaseConnector.shared().startObservingTransactions()

• Objective-C

    [[PurchaseConnector shared] startObservingTransactions];

Stop Observing Transactions

To stop observing transactions, you need to call stopObservingTransactions.

• Swift

    PurchaseConnector.shared().stopObservingTransactions()

• Objective-C

    [[PurchaseConnector shared] stopObservingTransactions];

Note: if you called stopObservingTransactions API, you should set autoLogPurchaseRevenue value before you call startObservingTransactions next time.

Testing the implementation in Sandbox

In order to test purchases in Xcode environment on a real device with TestFlight sandbox account, you need to set isSandbox to true.

• Swift

    PurchaseConnector.shared().isSandbox = true

• Objective-C

    [[PurchaseConnector shared] setIsSandbox:YES];

*IMPORTANT NOTE: Before releasing your app to production please be sure to remove isSandbox or set it to false. If the production purchase event will be sent in sandbox mode, your event will not be validated properly! *
