API (error Authentication Failed)

[elijahpaul]

I've been trying to access WHMCS using the External API.

 

I've seen a few threads on the forum regarding this, and as far as I can see I'm doing everything right. But if someone can point out what I may be missing I'd be grateful.

 

My PHP (from the WHMCS example) is as follows:

 

<?php
/* *** WHMCS XML API Sample Code *** */

$url = "https://mydomain.com/includes/api.php"; # URL to WHMCS API file goes here
$username = "adminusername"; # Admin username goes here
$password = "adminpassword"; # Admin password goes here

$postfields = array();
$postfields["username"] = $username;
$postfields["password"] = md5( $password );
$postfields["accesskey"] = "random_string"; <-- Have tried both with and without an access key.
$postfields["action"] = "getproducts";
$postfields["pid"] = "2";
$postfields["responsetype"] = "xml";

$query_string = "";
foreach ($postfields AS $k=>$v) $query_string .= "$k=".urlencode($v)."&";

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_TIMEOUT, 30);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $query_string);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
$xml = curl_exec($ch);
if (curl_error($ch) || !$xml) $xml = '<whmcsapi><result>error</result>'.
'<message>Connection Error</message><curlerror>'.
curl_errno($ch).' - '.curl_error($ch).'</curlerror></whmcsapi>';
curl_close($ch);

$arr = whmcsapi_xml_parser($xml); # Parse XML

print_r($arr); # Output XML Response as Array

/*
Debug Output - Uncomment if needed to troubleshoot problems
echo "<textarea rows=50 cols=100>Request: ".print_r($postfields,true);
echo "\nResponse: ".htmlentities($xml)."\n\nArray: ".print_r($arr,true);
echo "</textarea>";
*/

function whmcsapi_xml_parser($rawxml) {
	$xml_parser = xml_parser_create();
	xml_parse_into_struct($xml_parser, $rawxml, $vals, $index);
	xml_parser_free($xml_parser);
	$params = array();
	$level = array();
	$alreadyused = array();
	$x=0;
	foreach ($vals as $xml_elem) {
	  if ($xml_elem['type'] == 'open') {
		 if (in_array($xml_elem['tag'],$alreadyused)) {
		 	$x++;
		 	$xml_elem['tag'] = $xml_elem['tag'].$x;
		 }
		 $level[$xml_elem['level']] = $xml_elem['tag'];
		 $alreadyused[] = $xml_elem['tag'];
	  }
	  if ($xml_elem['type'] == 'complete') {
	   $start_level = 1;
	   $php_stmt = '$params';
	   while($start_level < $xml_elem['level']) {
		 $php_stmt .= '[$level['.$start_level.']]';
		 $start_level++;
	   }
	   $php_stmt .= '[$xml_elem[\'tag\']] = $xml_elem[\'value\'];';
	   @eval($php_stmt);
	  }
	}
	return($params);
}

?>

 

I've ensured that my IP is listed in the API IP Access Restriction section of the Security tab in General Settings.

 

And I've also double checked that my admin user has API access set in the Administrator Roles settings.

 

I've tried accessing the API via the access key method as well, but this didn't wok either.

 

So I cannot think of anything else that may causing the `error Authentication Failed` error.

 

Checking the Admin & Activity Logs show nothing, plus I've also checked the webserver error logs, but no joy.

 

Anyone got any ideas on what I'm missing, or where I can find a log of what error is happening?

Well that's embarrassing.

 

SOLVED!

 

My external webserver was rewriting URLs in an awkward manner.

 

All works fine now!
