Table Of Content

This Module is Built for

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

Adding The Connector To Your Project via Cocoapods:

Add to your Podfile and run pod install:

pod 'PurchaseConnector'

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 {
    [[PurchaseConnector shared] startObservingTransactions];
    [[AppsFlyerLib shared] start];
}

- (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.

  • 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! *
