Google Play and App Store provide the In-App Purchase (IAP) services. IAP can be used to sell a variety of content, including subscriptions, new features, and services. The purchase event and the payment process occurs on and handled by the mobile application (iOS and Android), then your backend needs to be informed about this purchase event to deliver the purchased product or update the user's subscription state.

Laravel In-App purchase comes to help you to parse and validate the purchased products and handle the different states of a subscription, like New subscription , auto-renew, cancellation, expiration and etc.

Installation

Install the package via composer:

composer require imdhemy/laravel-purchases

Publish the config file:

php artisan vendor:publish --provider="Imdhemy\Purchases\PurchaseServiceProvider" --tag="config"

Configuration

The published config file config/purchase.php looks like:

return [
    'routing' => [],

    'google_play_package_name' => env('GOOGLE_PLAY_PACKAGE_NAME', 'com.example.name'),

    'appstore_sandbox' => env('APPSTORE_SANDBOX', true),

    'appstore_password' => env('APPSTORE_PASSWORD', ''),

    'eventListeners' => [
        /**
         * --------------------------------------------------------
         * Google Play Events
         * --------------------------------------------------------
         */
        SubscriptionPurchased::class => [],
        SubscriptionRenewed::class => [],
        SubscriptionInGracePeriod::class => [],
        SubscriptionExpired::class => [],
        SubscriptionCanceled::class => [],
        SubscriptionPaused::class => [],
        SubscriptionRestarted::class => [],
        SubscriptionDeferred::class => [],
        SubscriptionRevoked::class => [],
        SubscriptionOnHold::class => [],
        SubscriptionRecovered::class => [],
        SubscriptionPauseScheduleChanged::class => [],
        SubscriptionPriceChangeConfirmed::class => [],

        /**
         * --------------------------------------------------------
         * Appstore Events
         * --------------------------------------------------------
         */
        Cancel::class => [],
        DidChangeRenewalPref::class => [],
        DidChangeRenewalStatus::class => [],
        DidFailToRenew::class => [],
        DidRecover::class => [],
        DidRenew::class => [],
        InitialBuy::class => [],
        InteractiveRenewal::class => [],
        PriceIncreaseConsent::class => [],
        Refund::class => [],
    ],
];

Each configuration option is illustrated in the configuration section.

i. Generic Configurations:

The generic configurations are not specific to a particular provider of the two supported providers (Google and Apple).

i.1 Routing

This package adds two POST endpoints to receive the Real-Time Developer Notifications, and the The App Store Server Notifications.

These routes can be configured through the routing key in the config file. For example:

[
    // ..
   'routing' => [
        'middleware' => 'api',
        'prefix' => 'my_prefix'
    ],
    // ..
];

i.2 Event Listeners

Your application should handle the different states of a subscription life. Each state update triggers a specified event. You can create an event listener to update your backend on each case.

use Imdhemy\Purchases\Events\GooglePlay\SubscriptionRenewed;

class AutoRenewSubscription 
{   
    /**
    * @param SubscriptionRenewed $event
    */
    public function handle(SubscriptionRenewed $event)
    {
        // do some stuff
    }   
}

Add the created listener to the associated event key.

    // ..
        SubscriptionRenewed::class => [AutoRenewSubscription::class],
    // ..

All events extend the \Imdhemy\Purchases\Events\PurchaseEvent abstract class, which implements the \Imdhemy\Purchases\Contracts\PurchaseEventContract interface. Check the Purchase Events section for more information.

ii. Google Play Configurations:

The following set of configurations are specific to google play:

ii.1 Google Application Credentials

Requests to the Google Play Developer API, requires authentication and scopes. To authenticate your machine create a service account, then upload the downloaded JSON file google-app-credentials.json to your server, and finally add GOOGLE_APPLICATION_CREDENTIALS key to your .env file and set it to the path of JSON file.

In the Cloud Console, go to the Create service account key page.
From the Service account list, select New service account.
In the Service account name field, enter a name.
From the Role list, select Project > Owner.
Click Create. A JSON file that contains your key downloads to your computer.
Upload the JSON file to your storage directory, or any other protected directory.
Set the .env key GOOGLE_APPLICATION_CREDENTIALS to the JSON file path.

ii.2 Google Play Package Name

The package name of the application for which this subscription was purchased (for example, 'com.some.thing').

iii. App Store Configurations

The following set of configurations are specific to the App Store.

iii.1 App Store Sandbox

The configuration key appstore_sandbox is a boolean value that determines whether the requests sent to the App Store are in the sandbox or not.

iii.2 App Store Password

Request to the App Store requires the key appstore_password to be set. Your app’s shared secret, which is a hexadecimal string.

Sell Products

Google Products

You can use the \Imdhemy\Purchases\Facades\Product facade to acknowledge or to get the receipt data from Google Play as follows:

use \Imdhemy\Purchases\Facades\Product;
use \Imdhemy\GooglePlay\Products\ProductPurchase;

$itemId = 'product_id';
$token = 'purchase_token';

Product::googlePlay()->id($itemId)->token($token)->acknowledge();
// You can optionally submit a developer payload
Product::googlePlay()->id($itemId)->token($token)->acknowledge("your_developer_payload");

/** @var ProductPurchase $productReceipt */
$productReceipt = Product::googlePlay()->id($itemId)->token($token)->get();

Each key has a getter method prefixed with get, for example: getKind() to get the kind value. For more information check:

App Store Products

You can use the \Imdhemy\Purchases\Facades\Product to send a verifyReceipt request to the App Store. as follows:

use Imdhemy\AppStore\Receipts\ReceiptResponse;
use \Imdhemy\Purchases\Facades\Product;

$receiptData = 'the_base64_encoded_receipt_data';
/** @var ReceiptResponse $receiptResponse */
$receiptResponse = Product::appStore()->receiptData($receiptData)->verifyReceipt();

As usual each key has a getter method.

Sell Subscriptions

Google Play Subscriptions

You can use the \Imdhemy\Purchases\Facades\Subscription facade to acknowledge or to get the receipt data from Google Play as follows:

use Imdhemy\GooglePlay\Subscriptions\SubscriptionPurchase;
use Imdhemy\Purchases\Facades\Subscription;

$itemId = 'product_id';
$token = 'purchase_token';

Subscription::googlePlay()->id($itemId)->token($token)->acknowledge();
// You can optionally submit a developer payload
Subscription::googlePlay()->id($itemId)->token($token)->acknowledge("your_developer_payload");

/** @var SubscriptionPurchase $subscriptionReceipt */
$subscriptionReceipt = Subscription::googlePlay()->id($itemId)->token($token)->get();
// You can optionally override the package name
Subscription::googlePlay()->packageName('com.example.name')->id($itemId)->token($token)->get();

The SubscriptionPurchase resource indicates the status of a user's inapp product purchase. This is its JSON Representation:

For more information check:

App Store Subscriptions

You can use the \Imdhemy\Purchases\Facades\Subscription to send a verifyReceipt request to the App Store. as follows:

use Imdhemy\Purchases\Facades\Subscription;
// To verify a subscription receipt
$receiptData = 'the_base64_encoded_receipt_data';
$receiptResponse = Subscription::appStore()->receiptData($receiptData)->verifyReceipt();

// If the subscription is an auto-renewable one, 
//call the renewable() method before the trigger method verifyReceipt()
$receiptResponse = Subscription::appStore()->receiptData($receiptData)->renewable()->verifyReceipt();

// or you can omit the renewable() method and use the verifyRenewable() method instead
$receiptResponse = Subscription::appStore()->receiptData($receiptData)->verifyRenewable();

Purchase Events

As mentioned the configuration section, Your application should handle the different states of a subscription life. Each state update triggers a specified event. You can create an event listener to update your backend on each case.

All triggered events implement Imdhemy\Purchases\Contracts\PurchaseEventContract interface, which allows you to get a standard representation of the received notification through the getServerNotification() method.

The retrieved notification is of type \Imdhemy\Purchases\Contracts\ServerNotificationContract which allows you to get a standard representation of the subscription using the getSubscription() method.

The subscription object provides the following methods:

getExpiryTime() returns a Time object that tells the expiration time of the subscription.
getItemId() returns the purchased subscription id.
getProvider() returns the provider of this subscription, either google_play or app_store.
getUniqueIdentifier() returns a unique identifier for this subscription.
getProviderRepresentation() returns either SubscriptionPurchase or ReceiptResponse based on the provider.

Here is an example of an auto-renewed subscription:

use Imdhemy\Purchases\Events\GooglePlay\SubscriptionRenewed;

class AutoRenewSubscription 
{   
    /**
    * @param SubscriptionRenewed $event
    */
    public function handle(SubscriptionRenewed $event)
    {   
       // The following data can be retrieved from the event
       $notification = $event->getServerNotification();
       $subscription = $notification->getSubscription();
       $uniqueIdentifier = $subscription->getUniqueIdentifier();
       $expirationTime = $subscription->getExpiryTime();
        
       // The following steps are up to you, this is only an imagined scenario.
       $user = $this->findUserBySubscriptionId($uniqueIdentifier);
       $user->getSubscription()->setExpirationTime($expirationTime);
       $user->save();        
        
       $this->notifyUserAboutUpdate($user);
    }   
}
