# Execute Payment Sample

This is the second step required to complete PayPal checkout. Once user completes the payment, paypal redirects the browser to "redirectUrl" provided in the request. This sample will show you how to execute the payment that has been approved by the buyer by logging into paypal site. You can optionally update transaction information by passing in one or more transactions. API used: POST '/v1/payments/payment//execute'.

require __DIR__ . '/../bootstrap.php'; use PayPal\Api\Amount; use PayPal\Api\Details; use PayPal\Api\ExecutePayment; use PayPal\Api\Payment; use PayPal\Api\PaymentExecution; use PayPal\Api\Transaction;

### Approval Status

Determine if the user approved the payment or not

if (isset($_GET['success']) && $_GET['success'] == 'true') {

Get the payment Object by passing paymentId payment id was previously stored in session in CreatePaymentUsingPayPal.php

$paymentId = $_GET['paymentId']; $payment = Payment::get($paymentId, $apiContext);

### Payment Execute

PaymentExecution object includes information necessary to execute a PayPal account payment. The payer_id is added to the request query parameters when the user is redirected from paypal back to your site

$execution = new PaymentExecution(); $execution->setPayerId($_GET['PayerID']);

### Optional Changes to Amount

If you wish to update the amount that you wish to charge the customer, based on the shipping address or any other reason, you could do that by passing the transaction object with just `amount` field in it. Here is the example on how we changed the shipping to $1 more than before.

$transaction = new Transaction(); $amount = new Amount(); $details = new Details(); $details->setShipping(2.2) ->setTax(1.3) ->setSubtotal(17.50); $amount->setCurrency('USD'); $amount->setTotal(21); $amount->setDetails($details); $transaction->setAmount($amount);

Add the above transaction object inside our Execution object.

$execution->addTransaction($transaction); try {

Execute the payment (See bootstrap.php for more on `ApiContext`)

$result = $payment->execute($execution, $apiContext);
