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\Amount; use PayPal\Api\Payer; use PayPal\Api\Payment; use PayPal\Api\RedirectUrls; use PayPal\Api\Transaction; session_start();

Payer

A resource representing a Payer that funds a payment For paypal account payments, set payment method to 'paypal'.

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

Amount

Lets you specify a payment amount. You can also specify additional details such as shipping, tax.

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

Transaction

A transaction defines the contract of a payment - what is the payment for and who is fulfilling it.

$transaction = new Transaction(); $transaction->setAmount($amount) ->setDescription("Payment description");

Redirect urls

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

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

Payment

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

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

Create Payment

Create a payment by calling the 'create' method passing it a valid apiContext. (See bootstrap.php for more on ApiContext) The return object contains the state and the url to which the buyer must be redirected to for payment approval

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

Get redirect url

The API response provides the url that you must redirect the buyer to. Retrieve the url from the $payment->getLinks() method

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

Redirect buyer to PayPal website

Save payment id so that you can 'complete' the payment once the buyer approves the payment and is redirected bacl to your website.

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

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