Start the SDK

The start must be done as soon as possible to catch every purchase / renewal. On iOS, initialise the SDK in your AppDelegate method didFinishLaunchingWithOptions to allow promoted In-App Purchase and support PSD2. This initialisation will allow tyou to access products prices instantly later in the app.

You will need an API Key that you can find in your App settings in the Purchasely Console.

Swift

import Purchasely

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
    Purchasely.start(withAPIKey: "API_KEY", appUserId: "USER_ID")
	return true
}

Objective-C

#import <Purchasely/Purchasely-Swift.h>

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
	// Override point for customization after application launch.

	[Purchasely startWithAPIKey:@"API_KEY"
			  appUserId:@"USER_ID"
			runningMode: PLYRunningModeFull
	              eventDelegate:nil
			 uiDelegate:nil
	  paywallActionsInterceptor:nil
		           logLevel: LogLevelInfo
			initialized: nil];
	return YES;
}

Kotlin

import io.purchasely.ext.Purchasely

Purchasely.Builder(applicationContext)
    .apiKey("API_KEY")
    .logLevel(LogLevel.DEBUG) // set to warning or error for release
    .userId("USER_ID")
    .runningMode(PLYRunningMode.Full)
    .stores(listOf(GoogleStore(), HuaweiStore()))
    .build()

// When you are ready for Purchasely to initialize,
// you must call start() method that will grab configuration and products
// from the selected stores.
Purchasely.start { isConfigured ->
}

Java

List<Store> stores = new ArrayList();
stores.add(new GoogleStore(), new HuaweiStore());

new Purchasely.Builder(getApplicationContext())
    .apiKey("API_KEY")
    .logLevel(LogLevel.DEBUG) // set to warning or error for release
    .userId("USER_ID")
    .eventListener(this)
    .runningMode(PLYRunningMode.Full.INSTANCE)
    .stores(stores)
    .build();

// When you are ready for Purchasely to initialize,
// you must call start() method that will grab configuration and products
// from the selected stores.
Purchasely.start(isConfigured -> {
    null;
});

React Native

import Purchasely from 'react-native-purchasely';

/**
* @params String apiKey
* @params StringArray stores : may be Google, Amazon and Huawei
* @params String userId
* @params Purchasley.LogLevel logLevel
* @params RunningMode runningMode
**/
Purchasely.startWithAPIKey(
  'API_KEY',
  ['Google'],
  'USER_ID',
  Purchasely.logLevelDebug,
  RunningMode.FULL
);

Cordova

/**
* @params String apiKey
* @params StringArray stores : may be Google, Amazon and Huawei
* @params String userId
* @params Purchasley.LogLevel logLevel
* @params Purchasely.RunningMode runningMode
**/
Purchasely.startWithAPIKey(
    'API_KEY', 
    ['Google'], 
    null, 
    Purchasely.LogLevel.DEBUG, 
    Purchasely.RunningMode.full
);

Flutter

/**
* @params String apiKey
* @params StringArray stores : may be Google, Amazon and Huawei
* @params String userId
* @params PLYLogLevel logLevel
* @params PLYRunningMode runningMode
**/
bool configured = await Purchasely.startWithApiKey(
        'API_KEY',
        ['Google'],
        null,
        PLYLogLevel.debug,
        PLYRunningMode.full
    );
    
if (!configured) {
        print('Purchasely SDK not configured');
        return;
}

Unity

...
private PurchaselyRuntime.Purchasely _purchasely;

_purchasely = new PurchaselyRuntime.Purchasely("userId",
			false,
			LogLevel.Debug,
			RunningMode.Full,
			OnPurchaselyStart,
			OnPurchaselyEvent);

The userID parameter is optional and allows you to associate the purchase to a user instead of a device.

The eventDelegate/eventListener parameter is optional and allows you to listen to all purchases events. You should implement it at least to know when the purchase is successfull.

The uiDelegate / uiListener parameter is optional and allows you to override UI dialog presented to user in case of error or success.

The logLevel parameter is optional and will display logs from the SDK according to the level set. We advise you to set it to warning or error for production

The stores parameter (for Android apps) is optional but purchase won't work without it. You need to pass a list of stores that are enabled for your application. The first store available in the user device will be the store used to make a purchase. In this sample, Google Play Billing will be used if available in user device, Huawei Mobile Services will be used otherwise.

The runningMode parameter is optional and allows you to use Purchasely with another In-App purchase system to prepare a migration. More details in our dedicated section.
