Как отменить подписку PayPal без учетной записи PayPal?

Вот что я в итоге сделал.

<?php
require 'core/init.php';
require 'core/conn.php';
/*The paypal_transactions table is a table I'm using to store the IPN data.  This is necessary to capture the Profile_ID/Subscr_ID.  The Custom parameter is being used to pass the username.*/

$profileid_sql = "select subscr_id from paypal_transactions where custom ='". escape($user->data()->username)."'";
$result=mysql_query($profileid_sql); 

      while($row=mysql_fetch_array($result)){ 
      $profileid = $row['subscr_id'];
      }


include 'functions/change_subscription_status.php';
change_subscription_status( $profileid, 'Cancel' );
header('Location: Cancelled.php');
?>

Функция change_subscription_status здесь ...

<?php

/**
 * Performs an Express Checkout NVP API operation as passed in $action.
 *
 * Although the PayPal Standard API provides no facility for cancelling a subscription, the PayPal
 * Express Checkout  NVP API can be used.
 */
function change_subscription_status( $profile_id, $action ) {

    $api_request = 'USER=' . urlencode( 'API_username' )
                .  '&PWD=' . urlencode( 'API_Password' )
                .  '&SIGNATURE=' . urlencode( 'API_Signature' )
                .  '&VERSION=76.0'
                .  '&METHOD=ManageRecurringPaymentsProfileStatus'
                .  '&PROFILEID=' . urlencode( $profile_id )
                .  '&ACTION=' . urlencode( $action )
                .  '&NOTE=' . urlencode( 'Profile cancelled at store' );

    $ch = curl_init();
    curl_setopt( $ch, CURLOPT_URL, 'https://api-3t.sandbox.paypal.com/nvp' ); // For live transactions, change to 'https://api-3t.paypal.com/nvp'
    curl_setopt( $ch, CURLOPT_VERBOSE, 1 );

    // Uncomment these to turn off server and peer verification
    // curl_setopt( $ch, CURLOPT_SSL_VERIFYPEER, FALSE );
    // curl_setopt( $ch, CURLOPT_SSL_VERIFYHOST, FALSE );
    curl_setopt( $ch, CURLOPT_RETURNTRANSFER, 1 );
    curl_setopt( $ch, CURLOPT_POST, 1 );

    // Set the API parameters for this transaction
    curl_setopt( $ch, CURLOPT_POSTFIELDS, $api_request );

    // Request response from PayPal
    $response = curl_exec( $ch );

    // If no response was received from PayPal there is no point parsing the response
    if( ! $response )
        die( 'Calling PayPal to change_subscription_status failed: ' . curl_error( $ch ) . '(' . curl_errno( $ch ) . ')' );

    curl_close( $ch );

    // An associative array is more usable than a parameter string
    parse_str( $response, $parsed_response );

    return $parsed_response;
}
?>

Используйте метод API PayPal ManageRecurringPaymentsProfileStatus (API Operation NVP), используя параметр ACTION, вы можете:

• Отмена - можно отменить только профили в активном или приостановленном состоянии.
• Приостановить - приостановить можно только профили в активном состоянии.
• Активировать - повторно активировать можно только профили в приостановленном состоянии.

Чтобы создать повторяющийся профиль, следуйте этому примеру (PHP):

// Parameters for SetExpressCheckout, which will be sent to PayPal

$padata['L_BILLINGAGREEMENTDESCRIPTION0']   = 'Product description';
$padata['L_BILLINGAGREEMENTDESCRIPTION0']   = $padata['L_BILLINGAGREEMENTDESCRIPTION0'] . 
' $'.$product->price.'/month';
$padata['L_PAYMENTREQUEST_0_DESC0']         = $padata['L_BILLINGAGREEMENTDESCRIPTION0'] . 
' $'.$product->price.'/month';
$padata['PAYMENTREQUEST_0_NOTIFYURL']        = 'http://site_url/paypal/ipn';
$padata['PAYMENTREQUEST_0_DESC']            = $product->name;
$padata['RETURNURL']                        = 'http://site_url/paypal/returnurl';
$padata['CANCELURL']                        = 'http://site_url/paypal/cancelurl';

$padata['PAYMENTREQUEST_0_ITEMAMT'] = $product->price;
$padata['PAYMENTREQUEST_0_AMT']      = $product->price;
$padata['L_BILLINGTYPE0']            = 'RecurringPayments';
$padata['L_PAYMENTREQUEST_0_NAME0']  = $product->name;
$padata['L_PAYMENTREQUEST_0_NUMBER0']= '322';
$padata['L_PAYMENTREQUEST_0_QTY0']  = '1';
$padata['L_PAYMENTREQUEST_0_AMT0']   = $product->price;


$paypal_data            = http_build_query($padata);
$httpParsedResponseAr   = $this->PPHttpPost('SetExpressCheckout', $paypal_data);

//Respond according to message we receive from Paypal
if("SUCCESS" == strtoupper($httpParsedResponseAr["ACK"]) || "SUCCESSWITHWARNING" == strtoupper($httpParsedResponseAr["ACK"])){

    //Redirect user to PayPal store with Token received.
    $paypalurl ='https://www.paypal.com/cgi-bin/webscr?cmd=_express-checkout&token='.$httpParsedResponseAr["TOKEN"].'';
    header('Location: '.$paypalurl);

}else{
    echo 'Error : '.urldecode($httpParsedResponseAr["L_LONGMESSAGE0"]).'';


}

Returnurl страницы:

Я использовал отдельный метод для публикации параметров в PayPal

private function PPHttpPost( $methodName_, $nvpStr_ ) {

$api_username   = '[email protected]';
$api_password   = 'QWEQWEWQEQWEQEQWE';
$api_signature   = 'WQEQWEQWEQWEWQEQWEQWEQWEQWEQWE.cT';
$api_endpoint    = "https://api-3t.paypal.com/nvp";
$version     = '124.0';

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $api_endpoint);
   curl_setopt($ch, CURLOPT_VERBOSE, 1);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, FALSE);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);

curl_setopt($ch, CURLOPT_POST, 1);
 
$nvpreq = "METHOD=$methodName_&VERSION=$version&PWD=$api_password&USER=$api_username&SIGNATURE=$api_signature&$nvpStr_";

curl_setopt($ch, CURLOPT_POSTFIELDS, $nvpreq);
$httpResponse = curl_exec($ch);

    if(!$httpResponse) {
        exit("$methodName_ failed: ".curl_error($ch).'('.curl_errno($ch).')');
}

    // Extract the response details.
    $httpResponseAr = explode("&", $httpResponse);

    $httpParsedResponseAr = array();
    foreach ($httpResponseAr as $i => $value) {
        $tmpAr = explode("=", $value);
        if(sizeof($tmpAr) > 1) {
            $httpParsedResponseAr[$tmpAr[0]] = $tmpAr[1];
         }
    }

    if((0 == sizeof($httpParsedResponseAr)) || !array_key_exists('ACK', $httpParsedResponseAr)) {

        exit("Invalid HTTP Response for POST request($nvpreq) to $api_endpoint.");

    }

    return $httpParsedResponseAr;

}

Другой способ отменить - внутри учетной записи пользователя:

1. Войдите в свою учетную запись PayPal.
2. Щелкните Профиль вверху страницы.
3. Щелкните Мои деньги.
4. Нажмите «Обновить» в разделе «Мои предварительно утвержденные платежи».
5. Нажмите «Отмена», «Отменить автоматическое выставление счетов» или «Отменить подписку» и следуйте инструкциям.
