Has anyone implemented the PayPal PHP SDK with an openssl certificate? - php

Question

I read the documentation about security and concerns, but I can see any example with how use a .pem file to autenticate to PayPal API V2, the classic version has this feature. I want to send payments but using this method.
Has anyone share some code to see?
this is my code
require __DIR__ . '/PayPal-PHP-SDK/autoload.php';
class PaymentPayPal
{
public static function SendPayment($member)
{
$apiContext = new \PayPal\Rest\ApiContext(
new \PayPal\Auth\OAuthTokenCredential(
'ClientID','ClientSecret'
)
);
$apiContext->setConfig(
array(
'log.LogEnabled' => true,
'log.FileName' => 'PayPal.log',
'log.LogLevel' => 'FINE'
)
);
$payouts = new \PayPal\Api\Payout();
$senderBatchHeader = new \PayPal\Api\PayoutSenderBatchHeader();
$senderBatchHeader->setSenderBatchId(uniqid())
->setEmailSubject("You have a payment");
$payouts->setSenderBatchHeader($senderBatchHeader);
$senderItem1 = new \PayPal\Api\PayoutItem();
$senderItem1->setRecipientType('Email')
->setNote('Thanks you.')
->setReceiver($member['email'])
->setSenderItemId(uniqid())
->setAmount(new \PayPal\Api\Currency('{
"value":"'.$member['amount'].'",
"currency":"USD"
}'));
$payouts->addItem($senderItem1);
try {
$output = $payouts->create(null, $apiContext);
var_dump($output);
$status = \PayPal\Api\Payout::get($output->batch_header->payout_batch_id, $apiContext);
var_dump($status);
} catch (Exception $ex) {
}
}
}
