README

PHP library that can be used to validate Amazon Store, Google Play, iTunes and Windows Store in app purchase receipts.

Requirements

• PHP >= 7.1

Getting Started

The easiest way to work with this package is when it's installed as a Composer package inside your project. Composer isn't strictly required, but makes life a lot easier.

If you're not familiar with Composer, please see http://getcomposer.org/.

1. Add iap-validator to your application's composer.json.

    {
        ...
        "require": {
            "kartina-tv/store-receipt-validator": "2.*"
        },
        ...
    }
   

2. Run php composer install.

3. If you haven't already, add the Composer autoload to your project's initialization file. (example)

    require 'vendor/autoload.php';

Play Store

Create service account Service Account flow and download credentials json file

use ReceiptValidator\GooglePlay\Validator as PlayValidator;

putenv('GOOGLE_APPLICATION_CREDENTIALS=path/to/credentials.json');
$client = new \Google_Client();
$client->useApplicationDefaultCredentials();
$client->setScopes(Google_Service_AndroidPublisher::ANDROIDPUBLISHER);

$validator = new PlayValidator(new \Google_Service_AndroidPublisher($client));

try {
  $response = $validator->setPackageName('PACKAGE_NAME')
    ->setProductId('PRODUCT_ID')
    ->setPurchaseToken('PURCHASE_TOKEN')
    ->validate();
} catch (Exception $e){
  var_dump($e->getMessage());
  // example message: Error calling GET ....: (404) Product not found for this application.
