/**
 * PayPal REST Capture Request
 *
 * Use this resource to capture and process a previously created authorization.
 * To use this resource, the original payment call must have the intent set to
 * authorize.
 *
 * To capture payment, make a call to /v1/payments/authorization/{authorization_id}/capture
 * with the authorization ID in the URI along with an amount object. For a
 * partial capture, you can provide a lower amount. Additionally, you can explicitly
 * indicate a final capture (prevent future captures) by setting the is_final_capture
 * value to true.
 *
 * ### Example
 *
 * Note this example assumes that the authorization has been successful
 * and that the authorization ID returned from the authorization is held in $auth_id.
 * See RestAuthorizeRequest for the first part of this example transaction:
 *
 * <code>
 *   // Once the transaction has been authorized, we can capture it for final payment.
 *   $transaction = $gateway->capture(array(
 *       'amount'        => '10.00',
 *       'currency'      => 'AUD',
 *   ));
 *   $transaction->setTransactionReference($auth_id);
 *   $response = $transaction->send();
 * </code>
 *
 * @see RestAuthorizeRequest
 * @link https://developer.paypal.com/docs/api/#capture-an-authorization
