Step by step implementation of PayPal Pay-Flow-Pro Advance

Implementation of paypal pay-flow-pro payment gateway is very easy in php. First of all you will have to be need two thing to implement payflow pro advance -

1-Pay-flow pro advance sdk
2-A testing account on paypal manager (

1- Pay-flow pro advance sdk -  To implement pay-flow-pro .You need two file. PayflowNVPAPI.php and index.php . You just need to create a folder with name "PayFlowTest" and save both of file PayflowNVPAPI.php and index.php togeather into the "PayFlowTest" folder .After that locate your folder in you local host directory or on your server.You can simply test it by entering test credit card number 4111111111111111 and expiry date .Expiry date much be greter than current date.

Note:  After testing successfully don't forgot to change my test account paypal credential with your own.

Now get set and go to implement payflow pro. Just copy the entire below code and  paste in your PayflowNVPAPI.php file.After that you need to create another file index.php


//// Helper functions
if (!function_exists('pre')) {
function pre($arr, $heading = NULL) {  
if (!empty($heading)) {    
echo "<p><b>$heading</b></p>";  
echo "<pre><code>\n" . print_r($arr,true) . "\n</pre></code>";
if (!function_exists('script_url')) {
function script_url() {
 return (@$_SERVER['HTTPS'] ? 'https://' : 'http://') . $_SERVER['HTTP_HOST'] . $_SERVER['PHP_SELF'];
// Set this to "live" for the live server, "pilot" for the test server, or "sandbox"
// for Payflow accounts created through a Website Payments Pro account on the Sandbox. global $environment;
if (!isset($environment)) $environment = 'pilot';
// parse_payflow_string: Parses a response string from Payflow and returns an
// associative array of response parameters.
function parse_payflow_string($str) {    
$workstr = $str;    
$out = array();         
while(strlen($workstr) > 0) {        
$loc = strpos($workstr, '=');        
if($loc === FALSE) {            
// Truncate the rest of the string, it's not valid            
$workstr = "";            
$substr = substr($workstr, 0, $loc);        
$workstr = substr($workstr, $loc + 1);
// "+1" because we need to get rid of the "="                 
if(preg_match('/^(\w+)\[(\d+)]$/', $substr, $matches)) {            
// This one has a length tag with it.  Read the number of characters            
// specified by $matches[2].            
$count = intval($matches[2]);                         
$out[$matches[1]] = substr($workstr, 0, $count);            
$workstr = substr($workstr, $count + 1);
// "+1" because we need to get rid of the "&"        
} else {            
// Read up to the next "&"            
$count = strpos($workstr, '&');            
if($count === FALSE) {
// No more "&"'s, read up to the end of the string                
$out[$substr] = $workstr;                
$workstr = "";            
} else {
$out[$substr] = substr($workstr, 0, $count);                
$workstr = substr($workstr, $count + 1);
// "+1" because we need to get rid of the "&"            
return $out;
// run_payflow_call: Runs a Payflow API call.$params is an associative array of
// Payflow API parameters.  Returns FALSE on failure, or an associative array of response
// parameters on success.
function run_payflow_call($params) {    
global $environment;         
$paramList = array();   
foreach($params as $index => $value) {        
$paramList[] = $index . "[" . strlen($value) . "]=" . $value;    
$apiStr = implode("&", $paramList);         
// Which endpoint will we be using?    
if($environment == "pilot" || $environment == "sandbox")     
$endpoint = "";   
else $endpoint = "";     
// Initialize our cURL handle.    
$curl = curl_init($endpoint);         
curl_setopt($curl, CURLOPT_RETURNTRANSFER, TRUE);         
// If you get connection errors, it may be necessary to uncomment    
// the following two lines:    
curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, FALSE);   
curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, 0);         
curl_setopt($curl, CURLOPT_POST, TRUE);    
curl_setopt($curl, CURLOPT_POSTFIELDS, $apiStr);         
$result = curl_exec($curl);    
if($result === FALSE) {      
echo curl_error($curl);      
return FALSE;    
return parse_payflow_string($result);

Now create an index.php file and just copy the entire below code and paste it into your index.php file .

Note : Dont forget to change you test account credential after successfully testing payflow pro.


global $environment;
$environment = "sandbox";
//Change it live if you are going for live transaction  require_once('PayflowNVPAPI.php');
//////// //// ////  First, handle any return/responses ////
/*Check if we just returned inside the iframe.  If so, store payflow response and redirect parent window with javascript.Purpose for adding this script is to get responce where ever you want on your php file otherwise paypal return response in iframe*/
if (isset($_POST['RESULT']) || isset($_GET['RESULT']) ) {   $_SESSION['payflowresponse'] = array_merge($_GET, $_POST);   echo '<script type="text/javascript"> = "' . script_url() .  '";</script>';   exit(0); }  echo "<span style='font-family:sans-serif;font-size:160%;font-weight:bold;'>PayPal Payments Advanced - Demo On</span> <p style='margin-left:1em;font-family:monospace;'>

if($success) echo "<span style='font-family:sans-serif;font-weight:bold;'>Transaction approved! Thank you for your order.</span>";
else echo "<span style='font-family:sans-serif;'>Transaction failed! Please try again with another payment method.</span>";

Hey bro,It helps me out but I'm getting an error which says "User Authentication failed".
USER_DEBUG [8]|DEBUG|RESULT=1&RESPMSG=User authentication failed.

Can you suggest me please where I'm going wrong.

Admin said...

Hi @Vimshi Krishan P - Thanks for your comment. Its looking you are missing something in configuration of payflow pro. Please checkout this link and let us know ... User-authentication-failed-Reason

Vamshi Krishna P said...

I checked them out.I'm doing it from Salesforce.
I have IP addresses included on the Pay flow white list. Besides this, I have "!!" special characters in password. If I consider this issue,there are other developers who went ahead and successful with the integration. This is confusing but still finding ways to solve this.
