    2.Provide the Application Name, Call Back Url and upload the application logo and click on save button to add the application.
    3.Generate your Client ID by clicking on "Generate Client Id" button.
    4.Generate your Client Secret and Client Token.
    5.Click on save button to generate your Connect Config. File.
    6.Download the Connect Config. File.
    
 Generate Bridge Config. File
    1.Click on "CSC Bridge".
    2.Select "Key Manager" option.
    2.Generate keys by clicking on to the “Generate Keys” button.
    3.Download the Bridge Config. File.

Use these configuration file into your code.

The illustrated code sample below provides the understanding of using the php integration kit.

Step 1. Create an encrypted payment request as in example file. (payment.php)

		<?php
		require_once 'includes/BridgePGUtil.php';

		$bconn = new BridgePGUtil();
		$p = array(
		//  'csc_id' => $_SESSION['user']['username'],
			'csc_id' => $_SESSION['username'],
			'merchant_receipt_no' => 'Recpt#' . rand(100,999),
			'txn_amount' => $_GET['amt'],
			'return_url' => 'http://merchant.csccloud.in/pay_success.php',
			'cancel_url' => 'http://merchant.csccloud.in/pay_success.php',
			'txn_amount' => $_GET['amt'],
			'product_id' => '1112101',
			'merchant_txn' => 'MW' . rand(1000, 9999)
		);

		$bconn->set_params($p);
		$enc_text = $bconn->get_parameter_string();
		$frac = $bconn->get_fraction();
		?>


		  <form method="post" action="http://pay.csccloud.in/pay/m2b/<?php echo $frac;?>">
			   <input type="hidden" name="message" value="<?=$enc_text;?>" />
			   <input type="submit" value="Pay" />
		  </form>

• Following is the wrapper for accessing bridge. (BridgePGUtil.php)

		<?php include_once __DIR__."/BridgePG.php";
		class BridgePGUtil {
		
		private $bridgePG;
		private $bridge_parameters;
		
		public function __construct(){
			$this->bridgePG = new BridgePG();
			$this->bridge_parameters = self::get_default_parameters();
		}
		
		private static function get_default_parameters(){
			$brj_params = array(
				'merchant_id'            => '11121',
				'merchant_txn'           => 'MDM101'.time(). rand(10,99),//'2016-06-21 18:11:58',
				'merchant_txn_date_time' => date('Y-m-d H:i:s'),//'2016-06-21 18:11:58',
				'product_id'             => '1112101',
				'product_name'           => 'my product',
				'txn_amount'             => '100',
				'amount_parameter'       => 'NA',
				'txn_mode'               => 'D',
				'txn_type'               => 'D',
				'merchant_receipt_no'    => '2016-06-21 18:11:58',
				'csc_share_amount'       => '0',
				'pay_to_email'           => '[e-mail]',
				'return_url'             => '',
				'cancel_url'             => '',
				'Currency'               => 'INR',
				'Discount'               => '0',
				'param_1'                => 'NA',
				'param_2'                => 'NA',
				'param_3'                => 'NA',
				'param_4'                => 'NA'
			);
			return $brj_params;
		}
		
		public function set_params($params){
			foreach($params as $p => $v){
				$this->bridge_parameters[$p] = $v;
			}
		}

		public function get_parameter_string(){
			$message_text = '';
			foreach($this->bridge_parameters as $p => $v ){
				$message_text .= $p . '=' . $v . '|';
			}
			$message_cipher = $this->bridgePG->encrypt_message_for_wallet($message_text, FALSE);
			return $this->bridge_parameters['merchant_id'] . '|' . $message_cipher;
		}
		
		public function get_bridge_message(){
			$d = "Invalid Bridge message";
			if($_POST['bridgeResponseMessage']){
				$c = $this->bridgePG->decrypt_wallet_message($_POST['bridgeResponseMessage'], $d, FALSE);
			}
			return $d;
		}
		
		public function get_fraction($ddhhmm = ""){
			$time_format = "ymdHis";
			$algo_num    = "883";
			if(!$ddhhmm)
				$ddhhmm = date($time_format, time());
			$frac = $this->large_op1($ddhhmm, $algo_num );
			$frac = $this->large_op2($frac, "" . (1000 - $algo_num) );
			return $frac;
		}
		
		public function large_op1($n0, $x0){
			$n = '' . $n0;
			$x = '' . $x0;
			$sz = strlen('' . $n);
			$vals = array();
			$tens = 0;
			for($i = 0; $i < $sz; $i++ ){
				$d = $n[$sz - $i - 1];
				$res = $d * $x + $tens;
				$ones = $res % 10;
				$tens = (int)($res / 10);
				array_unshift($vals, $ones);
			}
			if($tens > 0)
				array_unshift($vals, $tens);
			return implode("", $vals);
		}
		
		public function large_op2($n0, $x0){
			$n = '' . $n0;
			$x = '' . $x0;
			$sz = strlen('' . $n);
			$vals = array();
			$tens = 0;
			for($i = 0; $i < $sz; $i++ ){
				$d = $n[$sz - $i - 1];
				if($i == 0)
					$res = $d + $x;
				else
					$res = $d + $tens;
				$ones = $res % 10;
				$tens = (int)($res / 10);
				array_unshift($vals, $ones);
			}
			if($tens > 0)
				array_unshift($vals, $tens);
			return implode("", $vals);
		} }   ?>

Step 2. Process pay response to get status of payment as in sample file. (payment_response.php)

		<?php
		require_once 'includes/ BridgePGUtil.php';

		$bconn = new BridgePGUtil ();
		$bridge_message = $bconn->get_bridge_message();
		?>


		Encrypted Values:  <?php echo $_POST['bridgeResponseMessage']; ?>

		Decrypted Values: <?php $bridge_message; ?>
