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"; }
    
?>
