Ejemplo de PHP para PayPal Adaptive Payments ConvertCurrency API

Question

Estoy tratando de entender la nueva API de PayPal Adaptive Payments, específicamente la funcionalidad ConvertCurrency. ¿Alguien ha tenido algo de suerte con esto en PHP?

Documentación: https://www.x.com/docs/DOC-1400

Answer 1

Es muy fácil de convertir a dif. monedas usando Paypal's Adaptive Payments SDK. Suponiendo que tienes la información necesaria. (API nombre de usuario/password, etc) para realizar solicitudes a la API, se puede hacer de la siguiente manera:

<?php 

//First we need to include the class file of the Adaptive Payments 
include 'AdaptivePayments.php'; 

// Create an instance, you'll make all the necessary requests through this 
// object, if you digged through the code, you'll notice an AdaptivePaymentsProxy class 
// wich has in it all of the classes corresponding to every object mentioned on the 
// documentation of the API 
$ap = new AdaptivePayments(); 

// Our request envelope 
$requestEnvelope = new RequestEnvelope(); 
$requestEnvelope->detailLevel = 0; 
$requestEnvelope->errorLanguage = 'en_US'; 

// Our base amount, in other words the currency we want to convert to 
// other currency type. It's very straighforward, just have a public 
// prop. to hold de amount and the current code. 
$baseAmountList = new CurrencyList(); 
$baseAmountList->currency = array('amount' => 15, 'code' => 'USD'); 

// Our target currency type. Given that I'm from Mexico I would like to 
// see it in mexican pesos. Again, just need to provide the code of the 
// currency. On the docs you'll have access to the complete list of codes 
$convertToCurrencyList = new CurrencyCodeList(); 
$convertToCurrencyList->currencyCode = 'MXN'; 

// Now create a instance of the ConvertCurrencyRequest object, which is 
// the one necessary to handle this request. 
// This object takes as parameters the ones we previously created, which 
// are our base currency, our target currency, and the req. envelop 
$ccReq = new ConvertCurrencyRequest(); 
$ccReq->baseAmountList = $baseAmountList; 
$ccReq->convertToCurrencyList = $convertToCurrencyList; 
$ccReq->requestEnvelope = $requestEnvelope; 

// And finally we call the ConvertCurrency method on our AdaptivePayment object, 
// and assign whatever result we get to our variable 
$result = $ap->ConvertCurrency($ccReq); 

// Given that our result should be a ConvertCurrencyResponse object, we can 
// look into its properties for further display/processing purposes 
$resultingCurrencyList = $result->estimatedAmountTable->currencyConversionList; 
$baseAmount = $resultingCurrencyList->baseAmount->amount; 
$baseAmountCode = $resultingCurrencyList->baseAmount->code; 
$convertedAmount = $resultingCurrencyList->currencyList->currency->amount; 
$convertedAmountCode = $resultingCurrencyList->currencyList->currency->code; 

echo '<br /> $' . $baseAmount . ' ' . $baseAmountCode . ' is $' . $convertedAmount . ' ' . $convertedAmountCode; 

// And here just for the sake of knowing how we get the result from Paypal's API 
echo '<pre>'; 
print_r($result); 
echo '</pre>'; 

La salida debe ser algo como:

$15 USD is $159.75 MXN 

ConvertCurrencyResponse Object 
(
    [responseEnvelope] => ResponseEnvelope Object 
     (
      [timestamp] => 2010-04-20T13:27:40.278-07:00 
      [ack] => Success 
      [correlationId] => b940006680f6a 
      [build] => 1238639 
     ) 

    [estimatedAmountTable] => stdClass Object 
     (
      [currencyConversionList] => CurrencyConversionList Object 
       (
        [baseAmount] => stdClass Object 
         (
          [code] => USD 
          [amount] => 15 
         ) 

        [currencyList] => CurrencyList Object 
         (
          [currency] => currency Object 
           (
            [code] => MXN 
            [amount] => 159.75 
           ) 

         ) 

       ) 

     ) 

) 

Como se puede ver, es muy simple de usar ConvertCurrency API, simplemente descargue el SDK y comience a jugar con él;)
