PayPal PayFlow API錯誤

Question

我們使用PayFlow PayPal API進行定期付款，它給了我們一個問題。

我們向API發送金額爲29美元，但在PayPal日誌中僅顯示1美元。當我們詢問PayPal對此的支持時，他們表示您將發送$ 1。

請幫助我們。下面是代碼我們已經建立：

<?php 

$payflow_partner = 'PayPal'; 
$payflow_vender  = 'xxxxxxxxxxxxx'; 
$payflow_user  = 'xxxxxxxxxxxx'; 
$payflow_pwd  = 'XXXXXXXXX';

$first_name  = 'First Name'; 
$last_name  = 'Last Name'; 
$profile_name = $first_name.$last_name; 
$plan_amount = 29.00; 
$card_number = '4111111111111111'; 
$expiry_month = '05'; 
$expiry_year = '21'; 
$expiry   = $expiry_month.$expiry_year; 
$user_email  = 'test@example.com'; 
$start_date  = '01202017';

$ch = curl_init(); 
curl_setopt($ch, CURLOPT_URL, $payflow_url); 
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers); 
curl_setopt($ch, CURLOPT_HEADER, 1); // tells curl to include headers in response 
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); // return into a variable 
curl_setopt($ch, CURLOPT_TIMEOUT, 45); // times out after 45 secs 
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 0); 
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0); // this line makes it work under https 
curl_setopt($ch, CURLOPT_POSTFIELDS, $post_list); //adding POST data 
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 2); //verifies ssl certificate 
curl_setopt($ch, CURLOPT_FORBID_REUSE, TRUE); //forces closure of connection when done 
curl_setopt($ch, CURLOPT_POST, 1); //data sent as POST 
$result = curl_exec($ch); 
$headers = curl_getinfo($ch); 
curl_close($ch); 

echo $result; 

Answer 1

在您的文章數據要發送這兩個值：

AMT='.$plan_amount 
OPTIONALTRXAMT='.$plan_amount 

PayPal的documentation狀態，當OPTIONALTRX=S，它是不是在OPTIONALTRXAMT，才應使用你的情況。

該文檔還指出在您正在做的事情時被忽略。

注意：請勿在OPTIONALTRX = A時指定金額。金額被忽略。

因此，刪除可選參數。
