Payment integration in Payfort - php

Question

I'm working on Payfort API integration, and facing a problem with integrating using PHP. The link which I have followed mistake is in merchant reference. Where to get this reference?
<?php
$merchant_reference = 'TEST81003';
$redirectUrl = 'https://sbpaymentservices.payfort.com/FortAPI/paymentApi';
$return_url = 'https://love.ae/admin/public/login';
$requestParams = array(
'command' => 'PURCHASE',
'access_code' => 'bSCrsxniHsJqWtQ9ki15',
'merchant_identifier' => 'xPzUtIjC',
'merchant_reference' => 'TEST81003',
'amount' => 1050*100,
'currency' => 'AED',
'language' => 'en',
'customer_email' => 'alraqbani#gmail.com',
'token_name' => 'ali',
'return_url' => 'https://love.ae/admin/public/login',
'card_security_code' => '123',
);
// calculating signature
$shaString = '';
ksort($requestParams);
$SHARequestPhrase = '$2y$10$IGSCjOlk9';
$SHAResponsePhrase = '$2y$10$Ll6DBCeeH';
$SHAType = 'sha256';
foreach ($requestParams as $k => $v) {
$shaString .= "$k=$v";
}
if (1 == 1)
$shaString = $SHARequestPhrase . $shaString . $SHARequestPhrase;
else
$shaString = $SHAResponsePhrase . $shaString . $SHAResponsePhrase;
$signature = hash($SHAType, $shaString);
$requestParams['signature'] = hash($SHAType, $shaString);

//open connection
$ch = curl_init();

print_r($response);
curl_close($ch);
return $response;
?>

Answer 1

merchant_reference is a unique order number for each payment request.
It could be Primary key of the table or can be generated uniquely.
e.g.
$merchant_reference = '5000-'.time();
merchant_reference
Alphanumeric
Max: 40
