Cómo enviar dinero a paypal usando php

Question

He almacenado la dirección de correo electrónico de PayPal de los clientes en la base de datos y quiero enviarles dinero usando esa dirección de correo electrónico. Estoy usando PHP.

Cualquiera por favor sugiera cómo hacerlo.

Answer 1

Estaba buscando el mismo problema, esto es lo que funciona para mí. Probado en modo 'sandbox' y usando NVP (en lugar de SOAP). Su servidor debe ser compatible con CURL, con el fin de verificar que utilice:

<?php 
echo 'curl extension/module loaded/installed: '; 
echo (!extension_loaded('curl')) ? 'no' : 'yes'; 
echo "<br />\n"; 
phpinfo(INFO_MODULES); // just to be sure 
?> 

Si no está cargado o instalado pedir que su hostmaster o get it here, de lo contrario seguir adelante:

// sample code: https://cms.paypal.com/us/cgi-bin/?cmd=_render-content&content_ID=developer/library_code 

// eMail subject to receivers 
$vEmailSubject = 'PayPal payment'; 

/** 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'.

Buena suerte!
