Help me

Hi. I am building the betfair project in php.
I consider the lots of examples in the forum, so I use some examples.
Here are examples that I have used.

function getACookie($username, $password){
    
    $loginEndpoint= "https://identitysso.betfair.com/api/login";
    
    $cookie = "";
    
    $login = "true";
    $redirectmethod = "POST";
    $product = "home.betfair.int";
    $url = "https://www.betfair.com/";

    $fields = array
        (
            'username' => urlencode($username),
            'password' => urlencode($password),
            'login' => urlencode($login),
            'redirectmethod' => urlencode($redirectmethod),
            'product' => urlencode($product),
            'url' => urlencode($url)
        );

    //open connection
    $ch = curl_init($loginEndpoint);


    //url-ify the data for the POST
    $counter = 0;
    $fields_string = "&";
    
    foreach($fields as $key=>$value) 
        { 
            if ($counter > 0) 
                {
                    $fields_string .= '&';
                }
            $fields_string .= $key.'='.$value; 
            $counter++;
        }

    rtrim($fields_string,'&');

    curl_setopt($ch, CURLOPT_URL, $loginEndpoint);
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
    curl_setopt($ch, CURLOPT_POST, true);
    curl_setopt($ch, CURLOPT_POSTFIELDS,$fields_string);
    curl_setopt($ch, CURLOPT_HEADER, true);  // DO  RETURN HTTP HEADERS
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);  // DO RETURN THE CONTENTS OF THE CALL

    //execute post

    $result = curl_exec($ch);


//  echo $result;

    if($result == false) 
        {
                echo 'Curl error: ' . curl_error($ch);
        } 
    
    else 
        {
            $temp = explode(";", $result);
            $result = $temp[0];
            
            $end = strlen($result);
            $start = strpos($result, 'ssoid=');
            $start = $start + 6;
        
            $result = substr($result, $start, $end);
        }
    curl_close($ch);
    
    return $result;
}


//SPORTSAPI

function getAllEventTypes($appKey, $sessionToken)
{
 
    $jsonResponse = sportsApingRequest($appKey, $sessionToken, 'listEventTypes/', '{"filter":{}}');
    
    return $jsonResponse;
}
 
function extractHorseRacingEventTypeId($allEventTypes)
{
    foreach ($allEventTypes as $eventType) {
        if ($eventType->eventType->name == 'Horse Racing') {
            return $eventType->eventType->id;
        }
    }
}

function sportsApingRequest($appKey, $sessionToken, $operation, $params)
{
    $endpoint = "https://api.betfair.com/exchange/betting/json-rpc/v1";
    $url = $endpoint.$operation;
    //echo "URL: ".$url."\r\n";
    
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_POST, 1);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
    curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
    curl_setopt($ch, CURLOPT_HTTPHEADER, array(
        'X-Application: ' . $appKey,
        'X-Authentication: ' . $sessionToken,
        'Accept: application/json',
        'Content-Type: application/json'
    ));
     
    if($params != "")
        {
            curl_setopt($ch, CURLOPT_POSTFIELDS, $params);
        }
 
    $response = json_decode(curl_exec($ch));
 
    $http_status = curl_getinfo($ch, CURLINFO_HTTP_CODE);
    curl_close($ch);
 
    if ($http_status == 200) {
        return $response;
    } else {
        echo 'Call to api-ng failed: ' . "\n";
       
        echo  'Response: ' . json_encode($response);
        
    }
}

function getNextUkHorseRacingMarket($appKey, $sessionToken, $horseRacingEventTypeId)
{
    
     //$jsonResponse = sportsApingRequest($appKey, $sessionToken, 'listEventTypes', '{"filter":{}}');
      $params = '{"filter":{}}';
   /*
    $params = '{"filter":{"eventTypeIds":["' . $horseRacingEventTypeId . '"],
              "marketCountries":["GB"],
              "marketTypeCodes":["WIN"],
              "marketStartTime":{"from":"' . date('c') . '"}},
              "sort":"FIRST_TO_START",
              "maxResults":"1",
              "marketProjection":["RUNNER_DESCRIPTION"]}';
    */
    $jsonResponse = sportsApingRequest($appKey, $sessionToken, 'listMarketCatalogue/', $params);
    
    return $jsonResponse[0]->result[0];
} 

And here is the call instruction that I have used.

$allEventTypes = getAllEventTypes($appKey, $sessionToken); // Get all Event Types
                        
$horseRacingEventTypeId = extractHorseRacingEventTypeId($allEventTypes); //
                        
                                               
$nextHorseRacingMarket = getNextUkHorseRacingMarket($appKey, $sessionToken, $horseRacingEventTypeId); 

But the result is not good.

$nextHorseRacingMarket = getNextUkHorseRacingMarket($appKey, $sessionToken, $horseRacingEventTypeId); 

The response of this function is following.

Call to api-ng failed: Response: {"detail":{},"faultcode":"Client","faultstring":"D SC-0018"}

why? Please help me.
Thanks.

DSC018 and other common error codes are listed on page 257 of the manual. Help yourself to a copy if you haven't got one. Link below.

DSC018 indicates that a mandatory parameter has been omitted.

Which is odd, because there aren't any for ListEventTypes.

It's been a while since I've done any PHP, alas, so I've not spotted anything wrong with what you've coded.

Have you actually logged in and stored the session token for the calls to the API ?
Do you have a valid AppKey ?

I think you have not app key.
