Tranzila payment gateway : Not Authorized error message in response - php

Question

Trying to integrate tranzila payment gateway in my php project and testing with dummy credit card numbers on localhost before go live.I get php code from tranzila official document.
code given below
`
$tranzila_api_host = 'secure5.tranzila.com';
$tranzila_api_path = '/cgi-bin/tranzila71u.cgi';
// Prepare transaction parameters
$query_parameters['supplier'] = 'TERMINAL_NAME'; // 'TERMINAL_NAME' should be replaced by actual terminal name
$query_parameters['sum'] = '45'; // Transaction sum
$query_parameters['currency'] = '1'; // Type of currency 1 NIS, 2 USD, 978 EUR, 826 GBP, 392 JPY
$query_parameters['ccno'] = '12312312'; // Test card number
$query_parameters['expdate']= '0820'; // Card expiry date: mmyy
$query_parameters['myid'] = '12312312'; // ID number if required
$query_parameters['mycvv'] = '123'; // number if required
$query_parameters['cred_type'] = '1'; // This field specifies the type of transaction, 1 - normal transaction, 6 - credit, 8 - payments
// $query_parameters['TranzilaPW'] = 'TranzilaPW' ;
$query_string = '' ;
foreach($query_parameters as $name => $value) {
$query_string .= $name.'='.$value.'&' ;
}
$query_string = substr($query_string , 0 , - 1 ) ; // Remove trailing '&'
// Initiate CURL
$cr = curl_init();
curl_setopt($cr,CURLOPT_URL ,"https://$tranzila_api_host$tranzila_api_path");
curl_setopt($cr,CURLOPT_POST,1);
curl_setopt($cr,CURLOPT_FAILONERROR,true);
curl_setopt($cr,CURLOPT_POSTFIELDS,$query_string) ;
curl_setopt($cr,CURLOPT_RETURNTRANSFER,1);
curl_setopt($cr,CURLOPT_SSL_VERIFYPEER,0);
// Execute request
$result = curl_exec($cr);
$error = curl_error($cr);
if(!empty($error)){
die( $error );
}
curl_close ($cr);
// Preparing associative array with response data
$response_array = explode('&',$result);
$response_assoc = array();
if(count($response_array) > 1){
foreach($response_array as $value){
$tmp = explode('=',$value);
if (count($tmp) > 1 ){
$response_assoc [$tmp[0]] = $tmp[1];
}
}
}
// Analyze the result string
if(!isset($response_assoc['Response'])){
die($result."\n");
/**
* When there is no 'Response' parameter it either means
* that some pre-transaction error happened (like authentication
* problems), in which case the result string will be in HTML format,
* explaining the error, or the request was made for generate token only
* (in this case the response string will only contain 'TranzilaTK'
* parameter)
*/
}else if($response_assoc['Response'] !== '000'){
die($response_assoc['Response']."\n");
// Any other than '000' code means transaction failure
// (bad card, expiry, etc ..)
}else{
die("Success \n");
}

Here i replaced supplier with my original supplier name which i can't show here for security reasons.When run this code with actual supplier i got 'Not Authorized' error.
