I'm trying to access the Zoho API via Curl and PHP using the code below. It's able to get records, but when trying to insert some sample XML it's throwing a 4500 error code.

(I'm generating the tickets ok, which is being inserted into the URL below)

Where am i going wrong? I'm going bonkers - i've been banging my head against this brick wall for 2 evenings now!!

   

    
$api_key = 'hiddenfromview';
$zoho_url = 'http://crm.zoho.com/crm/private/xml/'; 
 
$xml ='<?xml version="1.0" encoding="UTF-8"?><Leads><row no="1"><FL val="Lead Source">paris hotels</FL><FL val="First Name">contacto 1</FL><FL val="Last Name">apellido</FL><FL val="Email">testing@testing.com</FL><FL val="Phone">1234567890</FL><FL val="Home Phone">0987654321</FL><FL val="Other Phone">1212211212</FL><FL val="Fax">02927272626</FL><FL val="Mobile">292827622</FL></row></Leads>';
 
// Create headers
$header[] = "Host: ".$zoho_url.'Leads/insertRecords';
$header[] = "Content-type: text/xml";
$header[] = "Content-length: ".strlen($xml) . "\r\n";
$header[] = $xml; 
 
$ch = curl_init();
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_URL, $zoho_url.'Leads/insertRecords?apikey='.$api_key.'&ticket='.$ticket);
curl_setopt($ch, CURLOPT_HEADER, $header);
 
//make the request
$result = curl_exec($ch);
