Регулярная оплата Paypal Express Checkout

Для успешной публикации вашего кода необходимо установить некоторые дополнительные параметры. Также я убрал некоторые дополнительные ошибки, которые вы обнаружите, если сравните два примера. Главное:

1. $returnURL и $cancelURL должны быть реальным URL и без метода urlencode()

2. $version должен быть установлен в urlencode('124.0');

3. Параметры для SetExpressCheckout должны быть установлены, как в примере.

4. Рекомендую протестировать вживую, просто выставьте цену в $0.01

   Следуйте примеру ниже:

 


/** SetExpressCheckout NVP example; last modified 08MAY23.
 *
 *  Initiate an Express Checkout transaction. 
*/

$environment = 'live';   // or 'beta-sandbox' or 'live'


/**
 * Send HTTP POST Request
 *
 * @param   string  The API method name
 * @param   string  The POST Message fields in &name=value pair format
 * @return  array   Parsed HTTP Response body
 */


function PPHttpPost($methodName_, $nvpStr_) {

    global $environment;



    // Set up your API credentials, PayPal end point, and API version.

    $API_UserName = urlencode('super_secret_username');

    $API_Password = urlencode('super_secret_password');

    $API_Endpoint = "https://api-3t.paypal.com/nvp";

    if("sandbox" === $environment || "beta-sandbox" === $environment) {

    }

    $version = urlencode('124.0');

    curl_setopt($ch, CURLOPT_POSTFIELDS, $nvpreq);



    // Get response from the server.

    $httpResponse = curl_exec($ch);


    if(!$httpResponse) {

    }
