Create Payment using PayPal as payment method

This sample code demonstrates how you can process a PayPal Account based Payment. API used: /v1/payments/payment

require __DIR__ . '/../bootstrap.php'; use PayPal\Api\Address; use PayPal\Api\Amount; use PayPal\Api\Payer; use PayPal\Api\Payment; use PayPal\Api\FundingInstrument; use PayPal\Api\RedirectUrls; use PayPal\Api\Transaction; session_start();

Payer

A resource representing a Payer that funds a payment Use the List of FundingInstrument and the Payment Method as 'credit_card'

$payer = new Payer(); $payer->setPayment_method("paypal");

Amount

Let's you specify a payment amount.

$amount = new Amount(); $amount->setCurrency("USD"); $amount->setTotal("1.00");

Transaction

A transaction defines the contract of a payment - what is the payment for and who is fulfilling it. Transaction is created with a Payee and Amount types

$transaction = new Transaction(); $transaction->setAmount($amount); $transaction->setDescription("This is the payment description.");

Redirect urls

Set the urls that the buyer must be redirected to after payment approval/ cancellation.

$baseUrl = getBaseUrl(); $redirectUrls = new RedirectUrls(); $redirectUrls->setReturn_url("$baseUrl/ExecutePayment.php?success=true"); $redirectUrls->setCancel_url("$baseUrl/ExecutePayment.php?success=false");

Payment

A Payment Resource; create one using the above types and intent as 'sale'

$payment = new Payment(); $payment->setIntent("sale"); $payment->setPayer($payer); $payment->setRedirect_urls($redirectUrls); $payment->setTransactions(array($transaction));

Create Payment

Create a payment by posting to the APIService using a valid apiContext. (See bootstrap.php for more on ApiContext) The return object contains the status and the url to which the buyer must be redirected to for payment approval

try { $payment->create($apiContext); } catch (\PPConnectionException $ex) { echo "Exception: " . $ex->getMessage() . PHP_EOL; var_dump($ex->getData()); exit(1); }

Redirect buyer to paypal

Retrieve buyer approval url from the payment object.

foreach($payment->getLinks() as $link) { if($link->getRel() == 'approval_url') { $redirectUrl = $link->getHref(); } }

It is not really a great idea to store the payment id in the session. In a real world app, please store the payment id in a database.

$_SESSION['paymentId'] = $payment->getId(); if(isset($redirectUrl)) { header("Location: $redirectUrl"); exit; }
