PHP Paypal RESTで支払いが失敗しましたJSONレスポンス

Question

ごめんなさい（最後の手段、頭の中で自分自身を撮っていない;-);それは明らかにどこかで私のせいだが、私はここや他の場所で検索したり、ドキュメントを読んだり、様々なことを試したりして過ごした。

いくつかのいずれかここで間違って何私をポイントしてください：

<?php 

$data = array(
    "intent" => "sale", 
    "redirect_urls" => array(
      "return_url" => "http://.../ok.html", 
      "cancel_url" => "http://.../cancel.html" 
     ), 
    "payer" => array(
      "payment_method" => "paypal" 
     ), 
    "transactions" => array(
      "amount" => array(
        "total" => "1.23", 
        "currency" => "GBP" 
       ) 
     ) 
); 

$ch = curl_init("https://api.sandbox.paypal.com/v1/payments/payment"); 

curl_setopt($ch, CURLOPT_VERBOSE, true); 
$logfile = fopen("curl_log.txt", "w"); 
curl_setopt($ch, CURLOPT_STDERR, $logfile); 

curl_setopt($ch, CURLOPT_HTTPHEADER, array(
    'Content-Type: application/json', 
    'Authorization: Bearer <long token returned from REST call', 
)); 
curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($data)); 
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE); 

$res = curl_exec($ch); 

curl_close($ch); 
fclose($logfile); 

?>

更新エラーメッセージまたはカール結果何があなたの$ data配列のような、

$data = array(
    "intent" => "sale", 
    "payer" => array(
      "payment_method" => "paypal" 
     ), 
    "transactions" =>array( 
      array(
       "amount" => array(
         "total" => "1.23", 
         "currency" => "GBP") 
      ) 
     ), 
    "redirect_urls" => array(
      "return_url" => "http://.../ok.html", 
      "cancel_url" => "http://.../cancel.html" 
    ) 
);
