Authorize Payment

This sample code demonstrates how you can authorize a payment. API used: /v1/payments/authorization https://developer.paypal.com/webapps/developer/docs/integration/direct/capture-payment/#authorize-the-payment

require __DIR__ . '/../bootstrap.php'; use PayPal\Api\Address; use PayPal\Api\Amount; use PayPal\Api\CreditCard; use PayPal\Api\FundingInstrument; use PayPal\Api\Payer; use PayPal\Api\Payment; use PayPal\Api\Transaction;

The biggest difference between creating a payment, and authorizing a payment is to set the intent of payment to correct setting. In this case, it would be 'authorize'

$addr = new Address(); $addr->setLine1("3909 Witmer Road") ->setLine2("Niagara Falls") ->setCity("Niagara Falls") ->setState("NY") ->setPostalCode("14305") ->setCountryCode("US") ->setPhone("716-298-1822"); $card = new CreditCard(); $card->setType("visa") ->setNumber("4417119669820331") ->setExpireMonth("11") ->setExpireYear("2019") ->setCvv2("012") ->setFirstName("Joe") ->setLastName("Shopper") ->setBillingAddress($addr); $fi = new FundingInstrument(); $fi->setCreditCard($card); $payer = new Payer(); $payer->setPaymentMethod("credit_card") ->setFundingInstruments(array($fi)); $amount = new Amount(); $amount->setCurrency("USD") ->setTotal(1); $transaction = new Transaction(); $transaction->setAmount($amount) ->setDescription("Payment description."); $payment = new Payment();

Setting intent to authorize creates a payment authorization. Setting it to sale creates actual payment

$payment->setIntent("authorize") ->setPayer($payer) ->setTransactions(array($transaction));

For Sample Purposes Only.

$request = clone $payment;

Create Payment

Create a payment by calling the payment->create() method with a valid ApiContext (See bootstrap.php for more on ApiContext) The return object contains the state.

try { $payment->create($apiContext); } catch (Exception $ex) {
