PHP Code

Prerequisite

Required necessary certificate key for the Payment Action Request and Response. Please refer Certificate Generation Guide.

Set account credentials

//Merchant's account information
	$merchantID = "JT01";		//Get MerchantID when opening account with 2C2P
	$secretKey = "7jYcp4FxFdf0";	//Get SecretKey from 2C2P PGW Dashboard

Set Inquiry Parameter

//Request Information  
	$version = "2.3";

Set payment action request information

//Construct signature string
	$stringToHash = $version . $merchantID;
	$hash = strtoupper(hash_hmac('sha256', $stringToHash ,$secretKey, false));	//Compute hash value

Construct payment action request message

//Construct request message
	$xml = "<IppOptionRequest>
			<version>$version</version> 
			<merchantID>$merchantID</merchantID>
			<hashValue>$hash</hashValue>
			</IppOptionRequest>";  

	include_once('pkcs7.php');
	
	$pkcs7 = new pkcs7();
	$payload = $pkcs7->encrypt($xml,"./keys/demo2.crt"); //Encrypt payload

Submit payment action request message

include_once('HTTP.php');
	
	//Send request to 2C2P PGW and get back response
	$http = new HTTP();
 	$response = $http->post("https://demo2.2c2p.com/2C2PFrontend/PaymentActionV2/PaymentAction.aspx","paymentRequest=".$payload);

Read payment response and Validate Hash

//Decrypt response message and display  
	$response = $pkcs7->decrypt($response,"./keys/demo2.crt","./keys/demo2.pem","2c2p");   
	echo "Response:<br/><textarea style='width:100%;height:80px'>". $response."</textarea>"; 
 
	//Validate response Hash
	$resXml=simplexml_load_string($response); 
	$res_version = $resXml->version;
	$res_timeStamp = $resXml->timeStamp;
	$res_respCode = $resXml->respCode; 
	
	
	//Compute response hash
	$res_stringToHash = $res_version . $res_respCode;
	
	$res_responseHash = strtoupper(hash_hmac('sha256',$res_stringToHash,$secretKey, false));	//Compute hash value
	echo "<br/>hash: ".$res_responseHash."<br/>"; 
	if(strtolower($resXml->hashValue) == strtolower($res_responseHash)){ echo "valid response"; } 
	else{ echo "invalid response"; }
	
?>
