PHP postback url google wallet IAP

Question

My postback php for google wallet in-app payments looks like this:

 $sellerIdentifier,
  \"aud\" => \"Google\",
         


        

Answer 1

to make a hotdog additionally do this:

 $sellerIdentifier,
  "aud" => "Google",
  "typ" => "google/payments/inapp/item/v1",
  "exp" => time() + 3600,
  "iat" => time(),
  "request" => array (
    "name" => "cake",
    "description" => "yum yum",
    "price" => "10.50",
    "currencyCode" => "USD",
    "sellerData" => "",
  )
);
$hotdog_payload = array(
  "iss" => $sellerIdentifier,
  "aud" => "Google",
  "typ" => "google/payments/inapp/item/v1",
  "exp" => time() + 3600,
  "iat" => time(),
  "request" => array (
    "name" => "hotdog",
    "description" => "yum yum",
    "price" => "5.99",
    "currencyCode" => "USD",
    "sellerData" => "",
  )
);

$cake_token = JWT::encode($cake_payload, $sellerSecret);
$hotdog_token = JWT::encode($hotdog_payload, $sellerSecret);
?>

pass both to a separate purchase() function in javascript (so purchase_hotdog() and purchase_cake()
