I get an error approving Android in-app subscriptions

[Serkan-Karacelikler]

My php code:

$packageName = "some packageName";
$productId = "some productId ";
$token = "some token here";

require 'vendor/autoload.php';
$client = new \Google_Client();
$client->setAuthConfig('ts.json');
$client->addScope('https://www.googleapis.com/auth/androidpublisher');
$service = new \Google_Service_AndroidPublisher($client);

$postBody = "test";
$para = "test";

$purchase = $service->purchases_subscriptions->acknowledge($packageName, $productId, $token,$postBody,$para);

//echo json_encode($purchase);

Error:

Fatal error: Uncaught TypeError: Argument 4 passed to Google_Service_AndroidPublisher_Resource_PurchasesSubscriptions::acknowledge() must be an instance of Google_Service_AndroidPublisher_SubscriptionPurchasesAcknowledgeRequest, string given, called in /home/serkanka/public_html/dgr/onayla.php on line 17 and defined in /home/serkanka/public_html/dgr/vendor/google/apiclient-services/src/Google/Service/AndroidPublisher/Resource/PurchasesSubscriptions.php:40 Stack trace: #0 /home/serkanka/public_html/dgr/onayla.php(17): Google_Service_AndroidPublisher_Resource_PurchasesSubscriptions->acknowledge('com.text.spec.s...', 'com.text.spec.s...', 'jlkehndmfjoaenc...', 'test', 'test') #1 {main} thrown in /home/serkanka/public_html/dgr/vendor/google/apiclient-services/src/Google/Service/AndroidPublisher/Resource/PurchasesSubscriptions.php on line 40

Hi @Serkan-Karacelikler,

As the error indicates, the 4th parameter must be an instance of Google_Service_AndroidPublisher_SubscriptionPurchasesAcknowledgeRequest. You've provided a string. It looks like you need to wrap your $body in the request instance:

$postBody = new Google_Service_AndroidPublisher_SubscriptionPurchasesAcknowledgeRequest();
$postBody->setDeveloperPayload("test");

$purchase = $service->purchases_subscriptions->acknowledge(
    $packageName,
    $productId,
    $token,
    $postBody
);

Additionally, I'm not sure what your $para variable is intended to represent, as the 5th argument to that method should be an array, and looking at the API reference, I do not see something that obviously corresponds to your variable. For this reason, I omitted it from my example.

I've been trying for days because I have little php knowledge and thank you very much. :)
