Paypal – Effettuare i pagamenti massivi con php

Programmazione
0

In questo post andremo a vedere uno script completo che ti permetterà di inviare dei pagamenti massivi (mass payment o bulk payment) tramite php su Paypal.

Talvolta in applicazioni CRM o software che gestiscono degli utenti è necessario effettuare dei pagamenti “a catena” di questi utenti, e con Paypal tutto questo è possibile con uno script che andremo a vedere qui sotto nel dettaglio.

Ovviamente va personalizzato sostituendo le credenziali di accesso a Paypal e le cifre del pagamento.

$vEmailSubject = 'Pagamento Paypal';
/** MassPay NVP example.
*
*  Pay one or more recipients. 
*/
// For testing environment: use 'sandbox' option. Otherwise, use 'live'.
// Go to www.x.com (PayPal Integration center) for more information.
$environment = 'sandbox'; // or 'beta-sandbox' or 'live'.
/**
* Send HTTP POST Request
*
* @param string The API method name
* @param string The POST Message fields in &name=value pair format
* @return array Parsed HTTP Response body
*/
function PPHttpPost($methodName_, $nvpStr_)
