/**
 * Stripe Payment Intents Authorize Request.
 *
 * An authorize request is similar to a purchase request but the
 * charge issues an authorization (or pre-authorization), and no money
 * is transferred.  The transaction will need to be captured later
 * in order to effect payment. Uncaptured charges expire in 7 days.
 *
 * A payment method is required. It can be set using the `paymentMethod`, `source`,
 * `cardReference` or `token` parameters.
 *
 * *Important*: Please note, that this gateway is a hybrid between credit card and
 * off-site gateway. It acts as a normal credit card gateway, unless the payment method
 * requires 3DS authentication, in which case it also performs a redirect to an
 * off-site authentication form.
 *
 * Example:
 *
 * <code>
 *   // Create a gateway for the Stripe Gateway
 *   // (routes to GatewayFactory::create)
 *   $gateway = Omnipay::create('Stripe\PaymentIntents');
 *
 *   // Initialise the gateway
 *   $gateway->initialize(array(
 *       'apiKey' => 'MyApiKey',
 *   ));
 *
 *   // Create a payment method using a credit card object.
 *   // This card can be used for testing.
 *   $card = new CreditCard(array(
 *               'firstName'    => 'Example',
 *               'lastName'     => 'Customer',
 *               'number'       => '4242424242424242',
 *               'expiryMonth'  => '01',
 *               'expiryYear'   => '2020',
 *               'cvv'          => '123',
 *               'email'                 => 'customer@example.com',
 *               'billingAddress1'       => '1 Scrubby Creek Road',
 *               'billingCountry'        => 'AU',
 *               'billingCity'           => 'Scrubby Creek',
 *               'billingPostcode'       => '4999',
 *               'billingState'          => 'QLD',
 *   ));
 *
 *   $paymentMethod = $gateway->createCard(['card' => $card])->send()->getCardReference();
 *
 *   // Code above can be skipped if you use Stripe.js and have a payment method reference
 *   // in the $paymentMethod variable already.
 *
 *   // For backwards compatibility, it's also possible to use card and source references
 *   // as well as tokens. However, a data dictionary containing card data  cannot
 *   // be used at this stage.
 *
 *   // Also note the setting of a return url. This is needed for cards that require
 *   // the 3DS 2.0 authentication. If you do not set a return url, payment with such
 *   // cards will fail.
 *
 *  // Do a purchase transaction on the gateway
 *  $paymentIntent = $gateway->authorize(array(
 *      'amount'                   => '10.00',
 *      'currency'                 => 'USD',
 *      'description'              => 'This is a test purchase transaction.',
 *      'paymentMethod'            => $paymentMethod,
 *      'returnUrl'                => $completePaymentUrl,
 *      'confirm'                  => true,
 *  ));
 *
 *  $paymentIntent = $paymentIntent->send();
 *
 *  // Alternatively, if you don't want to confirm it at one go for whatever reason, you
 *  // can use this code block below to confirm it. Otherwise, skip it.
 *  $paymentIntent = $gateway->confirm(array(
 *      'returnUrl'                => $completePaymentUrl
 *      'paymentIntentReference'   => $paymentIntent->getPaymentIntentReference(),
 *  ));
 *
 *  $response = $paymentIntent->send();
 *
 *  // If you set the confirm to true when performing the authorize transaction,
 *  // resume here.
 *
 *  // 3DS 2.0 time!
 *  if ($response->isRedirect()) {
 *      $response->redirect();
 *  } else if ($response->isSuccessful()) {
 *       echo "Authorize transaction was successful!\n";
 *       $sale_id = $response->getTransactionReference();
 *       echo "Transaction reference = " . $sale_id . "\n";
 *   }
