README

A PHP Library for consuming Dragonpay's Payment Switch API.

Quick start

Required setup

The easiest way to install this library is via Composer.

Create a composer.json file and enter the following:

{
    "require": {
        "coreproc/dragonpay-sdk": "dev-master"
    }
}

If you haven't yet downloaded your composer file, you can do so by executing the following in your command line:

curl -sS https://getcomposer.org/installer | php

Once you've downloaded the composer.phar file, continue with your installation by running the following:

php composer.phar install

Usage (TODO: update)

Setting up the Dragonpay Client

Require the autoloader and import the DragonpayClient:

require '../vendor/autoload.php';

use Coreproc\Dragonpay\DragonpayClient;

Set the merchant credentials:

$credentials = [
    'merchantId'        => 'merchant-id',
    'merchantPassword'  => 'merchant-password',
];

Logging is optional. It's set to false by default and can omitted when instantiating the client like so:

$client = new DragonpayClient($credentials);

When set to true, a third parameter is required for the logging directory.

$logging = true;
$logDirectory = 'logs';

Instantiate the client:

$client = new DragonpayClient($credentials, $logging, $logDirectory);

Checkout

Import the Checkout class:

use Coreproc\Dragonpay\Checkout;

Instantiate the Checkout class like so:

$checkout = new Checkout($client);

REST is the default web service used by the Checkout class. For using the SOAP web service, you can set the second parameter to SOAP:

$checkout = new Checkout($client, 'SOAP');

Transaction parameters from the merchant site:

REST service specific required parameters:

$params = [
    'transactionId' => 'transaction-id',
    'amount'        => '20000.00',
    'currency'      => 'PHP',
    'description'   => 'Playstation 4',
    'email'         => 'john@example.com',
];

SOAP service specific required parameters:

$params = [
    'transactionId' => 'transaction-id',
    'amount'        => '20000.99',
    'currency'      => 'PHP',
    'description'   => 'Playstation 4',
];

For getting the URL to Payment Switch:

The getUrl method returns a URL for redirecting to the Payment Switch manually.

$url = $checkout->getUrl($params);

Now $url is equal to:

Using the REST web service:

http://gw.dragonpay.ph/Pay.aspx?merchantid=merchant-id&txnid=transaction-id&amount=20000.00&ccy=PHP&description=Playstation+4&email=john%40example.com&digest=5ed24e0697800b569707542cff867eb2e9c681aa

Using the SOAP web service:

http://gw.dragonpay.ph/Pay.aspx?tokenid=8ca5a73275d5f54cz06219a09f935c26

Use the redirect method for redirecting to the generated URL:

$checkout->redirect($params);

Filtering Payment Channels

There may be instances wherein the merchant would want to filter the payment channels that they want to appear in Dragonpay’s payment selection page, or they may want to skip the Dragonpay page altogether and go straight to the payment details for a specific channel.

The merchant can implement this by providing a second parameter to the getUrl and redirect methods of the class Checkout respectively.

For a showing only a specific payment channel:

Online Banking: online_banking
Over-the-Counter Banking and ATM: otc_banking_atm
Over-the-Counter non-Bank: otc_non_bank
PayPal: paypal
Credit Cards: credit_card 
Mobile (Gcash): mobile
International OTC: international_otc

For redirecting directly to a payment channel:

Globe Gcash: gcash_direct
Credit Cards: credit_card_direct
PayPal: paypal_direct

Pass on the filter like so:

$filter = 'online_banking';

$checkout = new Checkout($client);

$checkout->getUrl($params, $filter);

$checkout->redirect($params, $filter);

Handling the Response

Import the Transaction class:

use Coreproc\Dragonpay\Transaction;

Pass in the client instance:

$transaction = new Transaction($client);

Required request data from Dragonpay Payment Switch:

$params = [
    'transactionId'   => $_GET['txnid'],
    'referenceNumber' => $_GET['refNo'],
    'status'          => $_GET['status'],
    'message'         => $_GET['message'],
    'digest'          => $_GET['digest']
];

Checking if the transaction is successful:

The isSuccessful method returns a boolean (true or false)

$status = $transaction->isSuccessful($params); // returns true/false

Support functions

The Payment Switch provides some supplementary functions allowing merchants to more tightly integrate and automate their systems. These functions are available using the REST or SOAP web service.

Transaction Inquiry

The merchant can inquire the status of a transaction by using this function.

Import the Transaction class:

use Coreproc\Dragonpay\Transaction;

Instantiate the Transaction class like so:

$transaction = new Transaction($client);

REST is the default web service used by the Transaction class. For using the SOAP web service, you can set the second parameter to SOAP:

$transaction = new Transaction($client, 'SOAP');

The inquire method returns the status of the transaction (string)

$transactionId = 'transaction-id';

// Returns one of the following:
// Success
// Failure
// Pending
// Unknown
// Refund
// Chargeback
// Void
// Authorized 
// Error
$status = $transaction->inquire($transactionId);

Cancellation of Transaction

The merchant can cancel a pending transaction by using this function.

The cancel method returns the status of the transaction cancellation (string)

use Coreproc\Dragonpay\Transaction;

$transaction = new Transaction($client); // OR $transaction = new Transaction($client, 'SOAP');

$transactionId = 'transaction-id';

$status = $transaction->cancel($transactionId); // returns Success or Failed

Sending of Billing Information

For additional fraud checking, the merchant can send the customer’s billing address by using this function.

The SOAP web service is required for this function.

use Coreproc\Dragonpay\Transaction;

$transaction = new Transaction($client, 'SOAP');

Required parameters to be sent to Payment Switch:

$params = [
    'transactionId' => '12345',
    'firstName'     => 'John',
    'lastName'      => 'Doe',
    'address1'      => 'Address 1',
    'address2'      => 'Address 2',
    'city'          => 'Quezon City',
    'state'         => 'State',
    'country'       => 'PH', // 2-char ISO country code (ex. PH, US, CA)
    'zipCode'       => '1116', // OPTIONAL
    'telNo'         => '(02)9123456',
    'email'         => 'john@example.com'
];

The sendBillingInformation method returns the status of sending of billing information. (string)

$status = $transaction->sendBillingInformation($params); // returns Success or Failed
