expedia hotel booking process for onsite booking without using any deep linking concept

I am using this GitHub code for hotel listing and hotel details section https://github.com/dyatlov/Expedia-PHP-API

for the booking process i am using this code:

$info = $expedia->getHotelInfo( $_REQUEST['hotelid'] );

echo '<pre>';
var_export( $info );

// book hotel
$expedia->set_method('POST');
$expedia->set_protocol('https://book.');
$result = $expedia->res( array(
    'hotelId' => $_REQUEST['hotelid'],
    'arrivalDate' => '7/27/2015',
    'departureDate' => '7/29/2015',
    'supplierType' => 'E',
    'rateKey' => '234be234234afd',
    'roomTypeCode' => 12345,
    'rateCode' => '123123',
    'chargeableRate' => '150.0',

    'room1' => 1,
    'room1FirstName' => 'John',
    'room1LastName' => 'Guest',
    'room1BedTypeId' => 1234,
    'room1SmokingPreference' => 'no',

    'email' => 'test@test.com',
    'firstName' => 'Tester',
    'lastName' => 'Tester',
    'homePhone' => '1234567',
    'workPhone' => '1234567',
    'creditCardType' => 'VI',
    'creditCardNumber' => '41111111111111111',
    'creditCardIdentifier' => '123',
    'creditCardExpirationMonth' => '05',
    'creditCardExpirationYear' => '2017',

    'address1' => 'travelnow',
    'city' => 'Moscow',
    'stateProvinceCode' => null,
